- In this video:
My personal logic and reasoning on why I don’t need a Hambini BB.
Nothing to do with the quality or design of the product, or my opinions of the man himself. 🙂
I just think you can get something as good for a 1/3 the price that will be within 0.5w of efficiency or basically the same. 🤷🏻♂️
If you do have one I am certainly not saying that it’s a bad product, in fact it’s extremely well made according to the reviews. It’s just from my perspective that level of machining that you are paying for is somewhat wasted on an average bicycle BB shell.
As I said to the last guy who asked me about his BBs, “ if I get dropped its because I’m fat and old, not because of my BB choice.” 😆

For as far back as I can remember, Hambini had always said we don’t need his bottom bracket, but if you want them he sells them.
Good point. 👍🏻
Yes I can't see anything Hambini could find to disagree with here. In fact this is probably one of the best adverts for one of his BB he could wish for, without lies.
It might as well this be the case. The timing though is problematic. This alone casts suspicion on your intentions. If i am allowed an outside opinion on your duel with Hambini this situation serves none.
You don’t need cigarettes but Benson & Hedges will sell you them if you want them.
@@Savrotirthis has zero relevance to their “feud”. This video is fair and factual because a lot of people fall into the fallacy that if you spend top dollar compared to mid range dollar, that the advantage will be immaculate, when in reality it just doesn’t show any perceivable difference.
Agree on the technical points - if your frame is in tolerance, a plastic shimano BB WILL last years. However do you truly believe there was no emotion with the title or the thumbnail? I think a fairer representation would be 'why i wouldn't buy a one piece correcting BB shell'. Other than that a well presented vid 👍
Hello. You might not believe this (and I totally understand that) but actually yes, there was no emotion in it as a subject. (Other than my strong feelings about spending too much money. 😅)
If I had a malicious intent I wouldn’t have said all the positive things I did and I wouldn’t have encouraged people to go see your excellent review.
I could have easily made a video full of wild accusations and false/misleading information and totally trashed them as a product just to be spiteful. (But I try not to be like that as a fallible human.)
Nope, I just wanted to give a different perspective on what is a very well made product. Any failure to do that is due to my failures as a video maker.
I was always planning to make this video specifically about the Ham BB. Only recently did someone ask me the question directly and I thought, why don’t I do a video on that, I was planning to anyway, I have the notes, let’s just get it out the way. 🤷🏻♂️
Also I think it better to post this now rather than after Hambini makes his next “reaming video” of me, because I don’t want this unrelated video subject to be seen as my response to that! (I don’t even want to respond to that coming video to be honest, I’ve proved my point and any further arguments on the subject are pointless.)
There is something different you must agree about the Ham BB Vs any other BB on the market. They are quite unique. The price, the craftsmanship, the perception of them being a solution to all BB problems…
The thumbnail is what it is, it gets people to listen to the information. The title is how I title all the videos in this series. (Why I’d never buy…)
But thank you for the comment and I think you make a valid point. 👍🏻
All the best, I look forward to your next educational video.🙂
Had he not used Hambinis name in the title, I still would have no idea who this gentleman is. Because he would not have popped up in my suggested videos list-so I’m leaning with you that there was purpose to that inclusion, emotional or not😉
@@reginaldscot165 I think you make a fair point. Its no different to H being very critical about a bike frame. We're all grown ups and we can make our own choice. I've a Chris King head set on my tourer I had built and I still wonder if it was worth the cost.
@@reginaldscot165 so spending too much money is a thing then? Discussing a BB from a handmade frame.... I think you made Hambini's point: if everything would be within tolerances he wouldn't need to make and sell BB's. But, even handmade frames, are not always within the needed tolerances. He showed that on numerous occasions. So stop using his name for clickbait. And you are doing this, and if you suggest you are doing this without any emotions you are only fooling yourself.
Pointless video
The Hambini BB solves a problem that you shouldn't have with your frame. It is quite expensive but I think that that price reflects the cost of that component if you make it in a small batch. The guy saw a problem risked his own money up front to provide a solution.
BBB might have subsequently produced something similar and with their manufacturing capabilities, reduced the cost. It is no reason to knock Hambini though!
You are slightly confused.
His BB doesn’t solve any problems unless it’s one of his custom BBs. If you buy his standard BB and your frame has a problem it won’t help. That’s why he has videos of people sending him their frames after they tried to fit his BB without success!
Your timeline is backwards, BBB and all other brands have been making that type of BB longer than Hambini. Yes his are slightly different, but basically other brands make something similar. BBB did not copy or come after him.
I’m not knocking it, they are very well made. I’m saying you can achieve the same thing at less cost! I’m saying for the benefit of people who don’t understand that and think that his BB Is magic or the only option.
If I were to knock him it would be based on the way he lies to his audience and makes up fake information. But I made other videos on that subject.
@@reginaldscot165😮😮
I am so greatful for time wasting, attention grabbing hobbies like this… they allow people like me to get away with Worse than murder, while two grown men debate bicycle BB’s and thousands of similar men grab their popcorn and tune in to the so-called entertainment. Almost better than alcohol
Im glad you are entertained. 😁
@@reginaldscot165 Thanks for your concern
@@princeandrew5430 Maybe you should focus on the people behind Epstein, not those that they delivered to the media.
I remember in the 1980's bottom bracket like Mavic were made of steel and they lasted. End of story. Carry on with bikes today is bullshit
This pretty much sums up what I’ve always thought about Hambini BBs, unless you have a dodgy frame there is no need for the expense. Although I don’t doubt that they are over engineered and high quality.
I think this vid is probably poorly timed. Regardless of what you say about this not being a personal video, it’s not going to go down well.
I agree with everything you said. 🙂👍🏻
Please just let it go. I think you both have value in your vids so stop sniping at each other!
👍🏻
I watched this video out of curiosity and have to say I agree with PT regarding the title and thumbnail. Regardless of how much you say you didn’t mean the video to come across a certain way, it’s clear to see from your viewing figures that the ones with Hambini in the title produce more views than most of your other material.
It seems unfair here to comment on something that you don’t appear to have tried, so I’ll add my experience in defence of the Hambini product, disclaimer: I am a fan of Hambinis work and his channel.
I own 4 bikes and the oldest is a lightweight rim bike frame from 2016/17 which uses an alu insert in the BB30 carbon frame and was originally specced with SRAM red etap 11spd. The bike had an appetite for non drive side bearings, something that makes sense when you listen to Hambinis explanation of how the SRAM system loads the NDS bearing, I decided to move to an external cup Bb from C bear which was ok for a while but then the NDS bearing began to get rough again. At this point I swapped to a Shimano crank and another c bear external cup BB. All was well until this BB started to wear out and developed a bit of play/roughness this time both bearings wearing evenly. I decided to put in a Hambini unit for a BB30 frame as it would future proof the bike meaning in the future only bearings would need sourcing as and when required.
I know this bike very well after 6 years, so when I fitted the BB it was a surprise to feel a few things that had improved as a result, occasional rear brake rub when out of the saddle has now gone, the front mech shifting seems better than before (never a strong point of first gen etap) and there is a much nicer feel to the bike when climbing out of the saddle. I attribute these things to the increase in stiffness around the BB area that the one piece unit has added.
It’s worth adding that had I bought the Hambini sooner I would potentially have avoided purchasing 2 C bear units which are non serviceable, I also tried a Wheels MFG unit which was unimaginably shit in terms of fit and creaked like a bastard from the first ride, they also claim the fit can be loose because of the thread together design but in my experience it simply didn’t work.
So whilst in your specific case you think a Hambini unit would be not needed I think there are many many frames out there that would benefit from them and not just frames that have specific fit or alignment issues.
The cost seems high and yet people are quite happy to drop similar money or more on a pricy GPS unit, shoes, clothing etc. I think considering the engineering quality on offer it’s a reasonable price when you think about the lifespan of the bike and future servicing costs .
Finally, in the sea of “that’ll do” engineering that the bike industry seems to run by I think it’s refreshing to find a product such as the Hambini BB, where it’s clear that quality really matters.
Sorry I got bored and didn’t read all this. As your opening statements were based on assumptions and you can’t possibly know my mind or motives it was pointless to read further. But I appreciate the time it must have taken.
All the best and safe cycling. 🙂👍🏻
@@reginaldscot165Well you are the content creator, if you don’t want to read people’s opinions on your content that’s up to you, but I’m not sure that’s a great thing. It seems to me that commenting on a product that you haven’t tried could also been seen as using assumptions on your part, but it’s your channel isn’t it!
A very well done video with a good explanation. Keep up the great work and stay above the fray.
Thank you kindly! 🙏🏻
It was always presented as a solution for problematic BB Shells, as they come often with carbon frames. I get your point, if you have a good frameset, a Hambini is overkill. But i don't think anyone, even he himself, would argue that. He doesn't produce these for the mass market (except for the Time frameset option, which is supposedly unnecessary with their frameset quality).
Thanks for pointing out quality alternatives that are well worth its money.
You are very welcome. Just trying to open up a different perspective on things. 🙏🏻🙂
I liked your bike repair stand. Cold you tell me the Brand and model??
Aldi, free vernier if you order before Christmas
Hambini bottom brackets aren't cheap but there's a reason why cheap isn't always the best option in the world of products. His BBs are often a solution to a bad frame or for someone thats say touring ir racing wanting longevity.
That’s true, cheap definitely doesn’t = good by default. 👍🏻
Believe what you want... The name calling hype is real, but the quality is questionable. There are other options that functionally are better at a fraction of the price.
Using 'Hambini' keyword in the title of your video must be jacking up your views ;)
Well it’s hard not to use his name when I’m talking about his product. 🙂 But I like to think people enjoy my perspective and analysis. 😉
Just when I was starting to dig you, you had to go ahead and do this. Internet drama is so outdated and exhausting. It doesn't attract a long-term audience. And you probably just alienated a big chunk of Hambini's audience who wouldn't have minded your setting him straight with facts in the instance where he was wrong, but this one reeks of pettiness.
I was asked I thought it a good question. Also it’s all factual and I make a point of saying that there is nothing wrong with his product, I just see better options for most people for less money.
@@reginaldscot165 It's not about the content. It's about the timing. IMO, it would be prudent to wait until you are on neutral terms.
@@reginaldscot165 There must be dozens of overpriced and not necessary products in the cycling world yet you chose this one. It certainly appears to me as an observer that this is petty vindictiveness on your part, despite your protests in the introduction. You are being disingenuous at best.
You are a better person than I. I would never buy a Hambini BB BECAUSE of my emotions! I mean, I'm pretty sure it's a good product, but his ego...
Well, “if I needed one” I would put my personal feelings aside, I’m not going to cut my nose off to spite my face. But thankfully other cheaper options are available. 🙂
Hambini BB is a work of art. When has bike ownership been purely about needs. It’s about wants, and I want the best. So go to the best. AKA Hambini. PS. Keep visiting your hairdresser
“When has bike ownership been purely about needs.” Well, if you look at most of the world who only use bikes to get from A to B I’d say it’s been that way for the majority of history. It’s only recently that cycling became the new golf. And when you say you want the best how do you know Ham BBs are the best? The only data we have for that is from the guy that sells them. No independent head to head testing has been done. 🤷🏻♂️
Just a thought. 🙂
@@reginaldscot165 thats true, but the testing from peak torque and its performance with industrial bearings do give it some merit. Even bikes arent individually aero tested head to head or lubricants, chains and pretty much anything advertised to make you go faster, an unfortunate truth of the industry.
Thanks for the video. Besides the horizontal and vertical alignment, the important alignment is the edge of the land edge of both side of the frame. This is where the BB is set for its position, and here is often some slating in any frame I have seen. If its pure press fit or treaded types, the BB will accept a tilt of the installation and by this troubles start. The types of BBinfinite or Hambini or whom either produce these types, have their relevance to meet these offsets.
My experience is, when using pressfit or treaded BB, only press or screw until the collar on the BB meets the frame at the first spot. The treaded often says 30Nm, but this will allow you to tilt the BB.
Yes that’s a good point I didn’t talk about. Thank you. 🙏🏻
To be honest Hambini bottom bracket is by design more concentric than all of these designs which means less friction which for you roadies equates to more saving a few edit:(less than half a watt - but still a saving) watts of power. If that your thing. He has a go at all manufactures for thier BB frames, designs, and Quality control and so he should because engineering wise it is shockingly bad for all bike manufacturers. Also the fact that as stated his is 20 microns which is a great machined tolerance less than 1 thou rounded up to 8 tenth of a thousand of an inch. is being put into a hole wherby the tolerance are different is wrong as you stated is wrong. Outside diam doesnt mstter as long as there is enough tolerance for the fit class. Then what we are left with is the exquisite 20 microns less than a thou tolerance for your bottom bracket to run on...as a mech tech i am salivating at that. 😂 Do you need it? No .. no . Yes Yes I want it. LoL 😂 and in there is his market
Totally agree 👍🏻🙂
Standard iso pressfit tolerances for a 40-50mm dia is about 20 microns, depending on the type of fit you want. Any machinist worth his salt can make you that. What Hambini charges is a complete ripoff. And it seems strange to me that his selling point is machining tolerances when the problem he addresses is misaligned or irregular shaped bottom bracket shells. What good does a 20 micron tolerance do if the shell itself is oval by 0.5mm? Or misaligned by 2 degrees?
For what he charges he should make you a completely custom bottom bracket with tolerances that are measured to your exact bike.
@@mofomartianp what class of fit? You can machine to 1/2 a thou of an inch then your grinding for anything further. ( metric born imperial machinist trained) hambini was 8 tenths of a thousand of an inch.
Hambini is fixing poorly alligned BB. By inserting his into your bike you have a decent machined to good tolerance and the extenal, I have no idea what your on about machining tolerance v missaligned or mishapen BB. Your obviously not a tech or an engineer.
If you clamp or press fit hambinis into your bike you WILL fix poorly aligned or mishapen BB and have a sweet running crank. But you dont see the value there, thats your and others opinion, but for those with money and the inkling to have a smooth sweet running crank there you go.
GJ.
thanks for the objective information😊
I try my best! You are welcome, I feel it’s important to get a different opinion. 👍🏻
Some times its not about price, but supporting craftsmanship. Chris King is a good example of this as well.
Actually no. I agree with that concept, but it doesn’t actually apply in this situation.
It’s not craftsmanship “The quality of design and work shown in something made by hand.” For example a hand made sword or violin.
His BBs are made on digitally controlled/computer controlled CNC machines and or auto-lathe. All you need to do in put a blank block or rod of aluminium in it, plug in your numbers/program and the machine does the rest. He uses the equipment at his workplace at the oil refinery during his day job. I know this because there is literally no way he could produce this level of tolerance of part on a manual lathe at home. The sort of machine he would need would cost around $50k up to a million. So what you are paying for is his design, not really craftsmanship.
@@reginaldscot165 Do you know if he is gonna sell us some oil in the future?
It depends of your perspective, I put a Hambo' in my custom Ti endurance/light all-road road bike for the same reason I put a Chris King headset in it, I plan to keep it (or at least the frame) forever, and endurance being my chosen discipline I will ride it A LOT and a long way. So having components on it that are long lasting, reliable, user serviceable and likely never (or at least for a very long time) need total replacement makes sense and will likely save me money and time in the long run.
My light "AliExpress" carbon climbing bike gets a £30 Shimano and (so far) the cheap ass headset bearings it came with, because the bike gets far less use, the frame cost about £400 and I will likely replace it with another of similar value in a few years time when I get bored of it. 🤷♂
That all seems totally logical to me. Sounds like a lovely bike as well! 👍🏻🙂
If you like Chris King Headsets so much why not use a Chris King Bottom as they are very high quality as well. I have numerous bikes with both Chris King Headsets and Bottoms and have never had any issues and they are immaculately made. Phil Wood components are very similar as well and last for ever......
@@jaycahow4667 I don't really know how to answer that. Its the "If you like Chris King Headsets so much" part that's throwing me. I have no loyalty to CK and I didn't choose Hambini over CK, I just chose. From all account CK makes excellent BB and so does Hambini.
All this to tell us that Hambini bottom brackets are the Mercedes of bottom brackets 😊
That about sums it up. 🙂👍🏻
The Maserati you mean
The 1980’s early 90’s mercedes before the quality nosedived 😂
Good explanation and demonstration of the law of diminishing returns.
Triple B make good stuff,bought 3 rolls of bar tape in celeste,a third the price of some others.
Oh yeah their cheap cork tape is awesome. Lasts forever. 👍🏻🙂
Oh my god! 😂. This guy!
Get a hambini bb guys especially if your shell is wonky !.
the tital of this video is provocative. Just for clicks.
The bottom line is hambinis bbs are really good.
Definitely worth every penny.
Top quality bearings
Keep banging your hairdresser ❤
It’s an accurate title. It’s why I (me personally) wouldn’t buy one. I never said they weren’t good, (the opposite in fact.)
However I disagree they are “worth every penny.” You can get the same performance for less.
And the sauce thickens....yay!!!
Indeed. 😅
I totally agree: for the price of 1 Hambini BB you can have 10 Shimano ones and regular ride will not feel the difference. And you can change them 2x a year and you are done for 5 years
Good calculation 🧮 👍🏻
If you want the best, get the best. It's not just about the product but also the customer service. I have run hambini bb's, they are the best quality! Happy to pay the price for a handmade piece of kit that will last for years & years.. plus if i have any issues, i know i can speak to the boss 😎
Well I can’t disagree with that.
I was waiting for that *ZING!*, and may I say it was delivered beautifully. 🤣😂🤣
Thank you 🙏🏻
Great video. I have a Praxis Press Fit BB on my bike and certainly have no complaints about it.
Regarding Litespeed framesets, what are your thoughts on upgrading from a PF30 to T47 BB? I would assume it's probably not worth the extra cost?
That’s correct, personally I don’t see the point when the PF30 is so simple and reliable in a titanium frame. 🙂👍🏻
The PF30 is the same as the T47 only the T47 is a threaded version.
For Ti from a reputable brand like LS (and steel from an equally reputable brand) I doubt PF30 will be an issue. Given the option on any other material or more mass produced frame it might be worth the extra upfront cost just to be safe(er). The only thing you might want to consider is future proofing, if the industry moves away from Press Fit (as it seems to be) and if like many people (myself included) you are going Ti because you want a "forever" (or a least a very long term) Bike/Frame then you could find good quality PF30 BB's harder to find in the future. But on the other hand I have T47 on a carbon Gravel bike and I've come across no issues that would make me want to avoid it unlike Press Fit.
Great video with some amazing arguments. What are your views on Phil wood and Chris King Bottom brackets?
Well I have only had experience with Chris King, wasn’t overly impressed, seemed a bit unnecessarily complicated to me. As you probably know it comes with unique and custom made bearings. So a real pain to get spare parts.
It’s all basically the same as the Ham stuff really. Yes they look nice and are smooth when you buy them but a bit over priced for what you get. If you can afford them and you don’t care about the money then why not. 🤷🏻♂️
For me I will just stick to the cheaper options.
@@reginaldscot165 I’ll definitely be looking toward the BBB stuff as and when I need a replacement.
When my F8 BB went south in 2019 I had no hesitation in getting Mr H’s BB as a replacement - seamless fit and yes I had to wait as was working in Gulf at the time but we’ll worth it - when my Felt TT fails (again) it’ll have the same
Cool 👍🏻
Ive got a threaded praxxis bb in a 2014 sworks press fit shell, running a campy ultra torque crankset (slagged of by Hambini) it has not creaked once in 5 years, and their customer relations is top notch.
Fantastic 👍🏻🙂
Just a rider here. I have an older carbon cannondale lefty mtb. It has BB30. It's just 2 bearings in the BB shell. I have changed them once in 14 years of fairly extensive riding. And that was only because they had been in there for years. I have never heard any creaking or had any issues. So here is a theory. BB30, technically, is the best BB design. HOWEVER, it requires the BB shell to be within tolerance. Since BB tolerance is quite sketchy, press fit BB's are noisy and there have been tons of complains. Hence, manufacturers are going back to threaded BBs since tolerances can be controlled in the process.
Yes that’s basically correct. It’s just the problem tends to be worse with some brands and materials. Glad you didn’t have any issues.
I think thou dost protest too much. Hahaha. Why pick a Hambini BB at a time like this? Disingenuous. But your viewpoint is entirely valid. Shots fired....again.
It’s bad timing, I didn’t think ham was making a response video and this was already in production, then I pushed it forward because I thought “if I’m going to get reamed I might as well have done something to deserve it!” 😅
Hmmm yes well I guess that's my point. It's like watching Game of Thrones with all the players involved in this curious web...I'm going back to watching the cricket until it all blows over. Lol.
@@mattskalicky ha ha why not 😁
I have a BB infinite T47 bottom bracket with the ceramic bearings on my T1sl and it’s rock solid . Gary is also a really good guy with next level customer service .
Excellent 👌🏻
The 'new' Canyon Grizl 5 come with a FSA BB86 Alloy Cups BB instead of Token Ninja Lite BB4124 . I want to change the crank anyway to a 180mm XTR Deore. Is there a BB that accepts the 24mm shimano spindle and which is of the screw type in the center like the Token to ensure that there will be no cracking from the PF 86,5 bb shell standard of the Grizl ?
Yes many, if it’s PF BB86 you have a huge wealth of choices. 👍🏻
@@reginaldscot165 ok thks
15:30 Yes, but fake bearings seem to be a significant issue these days, having been found even in supposedly 'reputable' bike shop chains, who claim their bearings are direct from supplier (they obviously turn out not to be). Imagine the average rider trying to find legit replacements, when most even aren't aware of the extent of the issue to begin with. Personally, I'll happily pay extra to get them from someone I can trust, artisan BB or not.
I can see the logic that line of argument.
The Hambini BB is exquisite, it's really beautiful, like jewelry or a fine watch. But a cheap Dura Ace BB works really good too. So I went with a Kogel ;-)
I agree, well actually I don’t. I think the Ham BB Is beautifully made and fantastically accurate… but I find them a bit ugly, they tend to look chunky and blocky… other Brand’s look more attractive. However 90% of it is inside your frame so it doesn’t really matter what it looks like. 🤭
Cheap Dura Ace !
@@Biggreydog $40 or less, so yeah, cheap.
Kogal is over priced
Meh, the Wheels MFG bottom bracket is superior in many ways. It's easy to remove if need be, easier to install, and (gasp) better engineered by a company that has specialized in making weird, hard to access, parts that are well though out for the mechanic. Hambini is just the Donald Trump of the bicycle world. So easy to get sucked into a world of poor cycling engineering with entertaining name calling, but in the end, it's all just smoke and mirrors. At best a hundai part at a Mercedes price. Believe at your own risk...
I am 100% confident that my " vintage" servicable bottom brackets for my square taper cranksets are every bit as efficient and far more durable than this modern stuff.
I think you might be right about that. Some square taper BBs I’ve had in the shop spin as smooth as silk.
@reginaldscot165 All mine do🤗 I've had what I called throwaway bbs and they've never lasted more than 7000 miles. They go from from " needs to be run in" , to " run in " to "has play" and there's NOTHING you can do about it, whereas with the old stuff, you can adjust to perfection and keep them at that level, just like a cup and cone hub.
hi reginald.
an old and retired mechanical engineer here with a couple of my own observations.
before measuring and determining whether something is perfectly round you need some better measuring equipment im afraid reginald,cheap verniers will only give a ballpark eyeball measurement and cannot be used to say whether something is perfectly round especially when considering the mating tolerances of 2 parts(especially so when the said parts tolerance fit have an effect on bearing performance and longevity). and did you check whether the opposing bearing holes were aligned with each other so the bearings were aligned without having a 'cocked' effect? apart from that great video.
Perfect was just a word to describe a BB shell that isn’t as crooked as the average carbon bike! 😅 But as nothing is perfect, not even close, please don’t take it too literally.
I was just making a point, that point was “My Ti BB not totally skew-whiff, so no issues. = don’t need ham BB. And if your BB is bent as a 9 bob note a Ham BB won’t help you any!”
Hopefully that’s clear? Yes I am fully aware that i lack fancy professional engineering tools for very precise measurements of holes. But, it’s not something I need in my current situation, I probably wouldn’t be able to get one in Brunei and even if I could on my income I couldn’t justify the cost for a video that made about $5. 😂
All the best Sir and thank you for your nice intelligent comment. Much appreciated. 🙂👍🏻
Hambini is going to have so much fun completely shredding your arguments in this video if he chooses to take the time and energy to do so. I appreciate your presentation of these legitimately more affordable BBs that are more appropriate alternatives in most situations. But you make so many inaccurate statements about measurement, precision, and structural equivalencies that Hambini is going to have a heyday if he chooses to engage. Either way, I appreciate your perspective when there are other CZcams channels presenting "wisdom and authority" that seem to worship Hambini with naive awe. I agree that most of us do not need or want a Hambini BB. I also appreciate Hambini's creativity and commitment to fixing problems that much of our industry has and does ignore.
Well as long as he/you enjoyed it that’s the main thing. Im sure he can, if he takes the time, it is only my opinion after all. 🙂👍🏻
All the best!
I got really curious about the screw together BBB bottom bracket since I got a new carbon mtb with PF92 in the beginning of the summer that has started creaking after a few hits to the cranks and pedals. Would the BBB "screw together" be more durable and withstand more abuse than the standard Shimano stuff?
Possibly, but you will need to check what the problem is first. Sometimes (most of the time) it’s not even the BB causing the problem. If the BB is creaking it might just need better installation, cleaning, greasing of the shell or any number of things that could improve the situation before you buy a new BB. The world’s best BB will still make sound if not installed correctly. 🙂
Good enough for you if it started creaking. Hope you all enjoy yr carbon junk from china.
@@reginaldscot165How many different ways can y thread something into a frame. Yr not old enough to remember their was a time when bikes just worked. You built them and they just worked beautifully. Then the little yellow communists got involved with all the little greedy English, American and European men and said we will build bikes out of plastic. Shit we don't care if carbon is toxic shit and creaks and breaks if you fall over, we can sell it too dumb kids that if they ride an ultra light bike they will be the next Eddy Merkx. Sad stupid world we live in now.
Do you know the size of the BBB BottomFit BB86/92 bearing. Is it an Enduro 24z37x7mm?
Cheers!
Correct on the size. No not enduro.
Heeeeeeeeelllllooooooooo!
I am a Hambini fan but what you’re saying is correct and fair.
If my expensive bike had a misaligned BB housing I’d be taking it back to the shop.
If you are a Hambini fan you might enjoy the other videos I did on our bearing removal dispute? 🙂
Nice vid Reg, I'm getting a Hambini BB for my new Trek Domane SL. Can't wait.
Cool 😎
@@reginaldscot165 - on a serious note, the BBB does look like lovely engineering.

What good does a 20 micron tolerance do if the shell itself is oval by 0.5mm? Or misaligned by 2 degrees?
For what he charges he should make you a completely custom bottom bracket with tolerances that are measured to your exact bike.
Yes that is the point I was trying to get people to understand. They are paying considerably more than they need to for no real world benefit. Yes, unless he is making you a custom BB or fixing your BB shell it’s not worth the Money. 🤷🏻♂️
I would buy one in a heartbeat but the conversion of euro - aud is massive. Currently have a Praxis in my SL3 Tarmac, 7years and same bearings
Nice 😊 👍🏻
Yes they are not cheap.
@@reginaldscot165 have no issue buying if living in europe, not a mass produced item and him using ntn bearings the price i think is fair.
Is it worth getting a BBB threaded BSA bottom bracket over the standard Ultegra one?
No I don’t think there is any significant advantage… the BBB one is easier to service however. As the Shimano one says “do not open” on it and it’s designed to never be serviced.
@@reginaldscot165 ccol, thanks. I have had problems on my Ribble CGR Ti with the dirt getting into the bb area as its my main winter bike. I have to put in two over the winter and regularly take it off and clean it up. I was just wondering if the BBB would be better in the long run and maybe solve this issue?
Thanks for the reply..
@@reginaldscot165 I was considering Hambini, hence how I found your video
Is a custom steel frame also inmune to poor quality bb shell construction, I suppose it’ll be fine but just wonder since My next frame will be of deliciously riding steel!
I would think you have a much better chance of a good BB shell in custom steel than almost any other situation or material. 🙂👍🏻
You and Hambini might not like to hear this - you are feuding! You are both clearly very good at what you do; there are many ways of being right. Occasionally we all trip up and it is hard to reconcile that with a belief that we are infallible. Just stop the feuding; your viewers are clearly intelligent enough to make decisions from the information you present. Thank you for your passion and expertise.
Welcome 🙏🏻
I always use the Shimano SM BB72-41B bottom bracket. They run super smooth and never creak in my carbon frame. They are reasonably cheap so I replace it every year as part of routine maintenance. What’s not to like.
Sounds like it works for you. 🙂👍🏻
If it’s that good, why do you replace it every year?
@@arzemagic it’s a cheap consumable item and I’m fussy about maintaining my bikes. They do last much longer than a year I just replace my one annually because I want to not because I need to.
@@clp91009 You could get the hambini one and change it every week not because you need to you might want to. If you were that particular you’d buy the best one that money could buy , surely that’s what I would do.
Agree with most on the video except the title that says, Hambini Bottom Brackets And Why I’d Never Buy One. My own view is Hambini BBs are the best of the best, agree you dont need one if your frame is %100, but if you bought a bike that was using BBs then a Hambini BB would be a far cheaper and better solution than endless cheap BBS or a new frame set, so perhaps you may change your mind on never buying a Hambini BB if you needed one?
The title remains honest and accurate for myself. 😁 But I’m sure I bought one in a parallel Dimension! 😎
LOL just hope are BBs are all parallel in this dimension.
What brand bottom bracket do you recommend for Bb86 with DUB crank set?
That’s a difficult one. The sizing is not a good combination, you will have to compromise a lot. Better to run a 24mm spindle in an BB86.
My canyon came with SRAM. rival, which I love. Are recommended an alternative crank? If so, what? :). BBInfinite has a single-piece BB for BB86/DUB, but they are the only brand I’ve found. I was hoping to find a less expensive option.
@@michaelfox6800 One of your 24 mm-spindled alternatives is Rotor ALDHU24 in the following configuration:
Rotor ALDHU24 crankarms
Rotor ALDHU24 spindle (steel)
Rotor 4-bolt 110 BCD spider
Rotor 4-bolt 110 BCD chainrings for SRAM AXS (round and Q-ring options available)
Due to your groupset's design, your Flattop chain has slightly larger rollers than the average chain, making it only suitable with gear teeth designed for this chain. This means for an aftermarket chainring to work with your chain, it needs to be designed for use with a SRAM Flattop chain.
The reason why Reginald said there's a compromise for large-spindled cranksets in BB86 is due to the smaller size of the ball bearings that'll be used in the bottom bracket's bearings and bearings with smaller balls generally don't last as long as those with larger balls.
Yes, BBInfinite bottom brackets aren't cheap, especially if you're drooling over the hybrid ceramic version, but due to the one-piece module design that provides perfect bearing angular alignment, your crankset will spin smoothly once it's broken in.
Hi, thanks for saving me money by showing excellent reasonably priced alternatives to Hambeenies BB. Thanks also for your video exposing his Ham fisted clumsy bearing extraction and demonstration of your elegant solution. I have purchased a set of expanding pullers and now feel like a proper engineer and less of a butcher . . . and what's with all that shouting ?
I’m very glad I could help and it’s nice to hear you have got some nice new tools to play with. 😍
I bought two, for two frames and they are brilliant
Cool 👌🏻
Why do you need bikes with seperate BB shell assemblies? What’s wrong with those seperate cups that screw on each side of the frame for external bearings? Or even those direct mount press fit internal bearings? FWIU people can glue them in if they creak. Mind you my bikes are all old bikes that don’t have these issues. So I’m curious about the need for an extra assembly inside the frame.
Yes it all very much depends on frame material, BB standard and if the frame was made in a precise manner. 🙂
@@reginaldscot165 I’m starting to like you Reg. I also prefer Ti over reinforced plastic resin. I really don’t understand the appeal of these disposable bikes
Thank you for this educational video, very interesting and informative.
So nice of you to say my friend. 🙏🏻
You could argue the same for watches, you can buy a Timex for £14 or you could buy a Rolex for £28,000, one you will throw in the bin and other can be passed down through the generations and go up in value.
I have bought two Hambini BB's and they are far smoother, save more watts than anything (way better than ceramics...)....the race versions. Watts mostly based on his data but also per zwift compared to a prior unit by another company (I think it was wheels manufacturing...been a long time). On other bikes I've had real issues with BB's so it is a place I just want things to work. Back in the day I had a phil wood BB last 17 years (I only changed it because I switched from a campy square hole type record carbon 10 after a series of campy units to a shimano sized rotor 3d now aldhu...it might still be going...at the same time the campy bb's were awful..the black carbon fiber one piece things....awful)....so over time these sorts of expensive BB's can perhaps save money.
You are right in that I probably spent more than I had to spend. But I feel like I got a wonderfully well made unit each time. I think he makes a really nice BB.
Silly - just because they are so nice and the tone seems overly harsh. You are correct - if the BB is good/well aligned bearing A is bearing A.
Not really silly if it’s saving people money and educating people that alternatives are available. And I’d be interested to hear how you know your Ham BB “save more watts than anything…” VS say BBB bearing with the same bearings pressed in? 🙂
21:00 This is often called "diminishing returns", not in the original sense of the word that was related to labor vs production, but in the sense of money vs performance.
The closer you get to the top of the line, the steeper the price increases for even the smallest increases of performance.
It applies to basically any product category.
If you want something very good, but not overpriced, it's often best to get something slightly better than what's in between average (50%) and the best (100%); so at about 80~85% of what's out there.
Excellent comment 🙂👍🏻
A small technical point I know, it is possible that a 'cylinder' has a constant diameter but is not round. Lookup constant diameter lobing (CDL). Otherwise I'd agree wholeheartedly with your conclusion. Also:czcams.com/video/jKAzHnkh0jQ/video.html
Thank you 🙏🏻 🙂
So the difference is really in the bearings?
I once bought some BBB sunglasses and they were junk. Infact all the BBB stuff looks pretty average quality. So i'm a bit weary of the brand.
I have 2 sets of BBB sunglasses and they have been great! Over the last 5 years they have come on leaps and bounds in quality. In fact many people I know have switched from Oakley Sunglasses to BBB because the quality is better. 😁
PS. All my bikes use BBB bearings of different prices and they all work great. 🙂
what should I use for my caad12 bb30a issue?
That depends on your issue and what spindle you are using?
Any screw type BB system will help eliminate noise. But you must first clean the shell well and prep with thick waterproof grease or my personal favourite copper grease. Then you can press and screw in your new BB. If you want something at a good price and decent quality try the BBB BBO-89. It’s for 24mm spindles.
If however your issue is something else? Misaligned shell? Then I can really help without seeing the issue myself. Try to find a reputable bike mechanic in your location. 👍🏻
you video concept is mostly flawed , because I have bb30 so there is only one option for the sleeve style bb , thats bbinfinate....HAMBONER's BBsystem is just a well made adapter for 24mm, cuz he hates sram and thinks everyone should buy the mechanically superior shimano...So i was looking fior a BB like the token NINJA i use for a bb90 trek, I was hoping one of these styles might solve the annoying caad12 issues.... Basically cdale made the caad12 more leaning towards their own parts so the options for 3rd party parts are limited in some areas..... the 13 is even worse, main reason why I wouldn't want a another bb30 , maybe look or time have larger bbs that allow a size down to 30mm.... Point is we need options beyond pressing bearings into raw aluminum frames!
@@reginaldscot165
Even if the bearings are SKF they are not going to be expensive do you think SKF make more than 1 bearing a day.
A set of 6806 is £36 + VAT. SKF or NTN alike. Important to buy only from their approved channels as there are lots of fakes on the market.
Depends on what type you buy but about $20 USD each.
What is the manufacture of that Titanium Frame
Litespeed
I have exacly the same Praxis Works BB on my Focus Cayo (GXP Sram with horrible spindle solution), whci had issues from the very beginning, in my TIME I used Wheels, manufactiring whcih is superior quality for less money, however in recent year WheelManufacturing has double price, with basic steel bearing. WH is much smoother, but a;so the TIME's BB shell is absolutly perfect. Any treaded BB is flexy and it WILL change over time is alighment anyway. Antural Hambini BB costs fortune, but peopr spending absolutly stupid money of bike gadgets, (eg super lighweight frameset worh in realitty 1/10 of price) or wheelsets, bike computers, and so on. So his solid down to eath precise machined piece of metal, giving real reflection of quality is nothing... Hambini brand was created because of: badly designed, manufactured, and super expensive "branded" bike manufacturers. Period.
Excellent points 👍🏻
I'm curious as to how tight the machining tolerances is for the praxis BBs compared to Hambini BBs. If machining quality is higher, as hambini likes to claim, then perhaps they are worth the extra money he is charging. In a world where people are willing to shell out hundreds of dollars to save a few grams why would you be surprised they won't do the same to save half a watt?
Yes I understand, but the point Peak Torque makes is that that level of tolerance is wasted on a bike BB shell. So really you aren’t getting any more out of it than you would a cheaper BB with the same quality bearings pressed in? 🤷🏻♂️🙂
@@reginaldscot165 isn't it odd that the very place you put all your power through would be an area to skimp on? People are spending hundreds/thousands on carbon frame bikes but happy to cut back a hundred on the BB where all of their power goes through?? Kind of silly if you ask me. Money better spent than getting super light carbon bottle holders or thinking that putting in proprietary ceramic speed bearings in will help. As an engineer speaking I will take quality bearings made by SKF that I can get at any half decent hardware shop pretty much anywhere in the world over specific proprietary bearings that if they actually provided the gains they claim, would be used everywhere in the manufacturing world. Using the Hambini BB allows me to do that.
so the only question I really have is... why doesn't your frame just have recesses to press bearing directly into it without the need for a bottom bracket?
I suppose that would radically limit the options available and potentially cause sound problems that other frames that do that often suffer from. 🤔
I have an early 90s Merlin Ti mountain bike that has exactly that: two bearings, two circlips and an axle. Have changed the bearings once.
Its good to see your pen's working 😜
Joking aside, being a MTBer I've always wondered why roadies have so much trouble with BBs but maybe they don't, maybe its just 'cause I watch Hambini videos and assume this is a common problem?
Another reason might be because on an MTB you can ride through some mud and lose 5% efficiency so you'd never notice a slightly out BB. I've also never heard of a MTBer talk about balancing wheels for the same reason. I can easily believe that roadies put a very high amount of torque through a BB climbing an Alp but also an MTB has far more heavy impacts through the BB than a road bike so I'm not sure which stresses/wears the BB more...
I'm not trying to troll roadies here, I'm honestly curious. I consider myself a cyclist with an interest in engineering first, a MTBer second.
Yeah I think it’s mostly MTB guys have a different attitude, they don’t care as much and probably don’t notice. On a quiet bit of road you can start to hear everything wrong with your bike as a roadie. 😂
Bravo. Good commercial for Hambini.
Now tell me. If not Hambini. What bottom bracket to buy for a 24mm BSA track bike where accelerations and very high torque is of the essence
Normally track bikes use square taper still. You can’t beat them to be honest.
@@reginaldscot165
Actually, the dura ace 7710/7700 works!
Having a carbon rocket and a few other track bikes I was surpriced the old BBs handeled the torque much better and gave relative better accel than the crappy DA 9100.
Swapping to a mechanical better system changed that.
Would a «box bearing» or squate taper be even better?
Might be, but going from the cups only to more solid cups and alu sleeves shure gave a huge improvement. Nothing ti be dissed
Very smart person, same argument as "I'd never buy an electronic groupset because i ride fixies!" nonsense video.
But that argument would make sense if you did ride a fixie? Also, I wouldn’t buy Di2 as well. 😁
Brilliant! I've never seriously considered Hambini BBs as a solution for customers' bikes for the very same reasons and, as such, have never actually bothered to look into this. Do you know of those one piece press-in BBs he makes would void the manufacture warranty? I've always promoted wheels manufacturing thread-together BBs for solving misaligned BB shells. With all the shade he throws at bike manufacturers I'd be surprised if they warrantied a frame if you rammed a Hambini BB through the frame and it cracked.
Im not sure where you would get with the warranty, but its unlikely to go well. But it would be silly to push in anything before checking the hole. That’s actually good advice in all life’s situations. 😅
@@reginaldscot165 Hambini has a very detailed installation / removal guidance webpage and specifically advises to measure the shell internal diameter before the installation and not to force the bb in if the force necessary appears to be excessive. You are right though that the generic ones won't fix every frame issue and in fact he has posted a number of videos with frame sets sent to him by his customers who had originally installed a generic one, but experienced further issues and needed a custom made one.
As for the waiting time, during the height of the pandemic it was a couple weeks, nowadays it is usually a week from joining the waiting list. I have got 5 of his bottom brackets: 3no. bb65 and 2no. bb386.
Calipers are good for estimating, Micrometers for actual measuring. That's not opinion it's fact.
Agreed. I’m not disputing that fact.
You've really done this video beautifully! More power to you reginald! Everything you said was on point especially on the topic of his custom servicing, and the price differences involved between the products. If i happen to buy another bike, i would definitely want to try the BBB bottom bracket with an NTN bearing inside.
And now i have to wait for his reply to you to see how he comes up with another comical BS again. 😆
Thank you so much, that’s very generous. Im glad you found it useful and yes there are plenty of good alternative brands available at much reduced cost. 🙂👍🏻
It’s the law of diminishing returns, that said I aspire to a Hambini BB and will fit one on my next bike, which will be bespoke built. I like different and Hambini is certainly different! 🤣
Agreed 👍🏻
Why does the Praxis BB sleeve have holes in it?
For weight reduction and drainage. If you have a fully sealed BB and water does get in and it can’t dry you will get serious rust.
@@reginaldscot165 I suspected it mgiht be. I've never experienced serious rust, I currently use Chris King and Race Face Cinch which is aluminium. But bearings are steel.I service my bike properly, never had any issues. Despite riding in snow, deep puddles, in salty winter conditions. Some are afraid of salty water, dirt getting on the axle due to no sleeve, I saw some commented about it with Hope Tech BB, that did not have a sleeve. I had rust before, but it was junk Race Face BB.
3:38 - it's also machined to a precision fit ... this bottom bracket is completely round.
Not necessarily true. If it was welded and then machined, it has a better chance of ending up round, but welding adds stress and machining can give that stress somewhere to go. Thin parts like that bottom bracket shell often distort after, and as a result of, machining. If it was machined and then welded, all bets are off.
If your Scott was so out of round as to make it impossible to get the bottom bracket in without "sanding it down" - I assume you don't own or have access to reamers, which would have helped keep the two sides concentric if nothing else - the frame is a fail. But you know that. I'm assuming it was a customer bike and you told them they should probably warranty it but you could fix it if they were somehow attached to it. I digress.
5:41 - What's nice about these is that they don't need a bottom bracket to be perfectly round, they just need the aperture to be big enough to fit the actual cup
Not entirely true. If you have an out of round BB shell designed for press fit BB, and you're forcing a press-fit sized BB in there, the loading on the BB (and the shell) will be uneven. This will result in distortion of both the BB and the shell, and that distortion will result in extra load on the bearings, and probably early failure. Also, the shell will end up "giving" a little, and your fit won't be as tight as it's supposed to be. Sure, a BB of that type won't fall out, but it will slop about, particularly in a carbon frame. slop = wear = bad mojo.
7:19 - Your measuring is hilariously awful. Even a top of the range mitutoyo digimatic is only claimed to be accurate within 0.05mm, and that in a temperature controlled room. Sure, you'll get a pretty accurate variance between two readings of the same order of size taken back to back, so if you were somehow able to get accurate bore readings that were different by 0.01mm, you could be pretty sure that they actually differed by ~0.01mm, plus or minus at least another 5 microns. But guesstimators are not the right tool for making those measurements. you're as well off using a bloody ruler. Bore gauge + micrometer, internal mics, go / no go gauges, all of this is stuff you could use and get a meaningful result. As you're someone who does BB installs on paying customer's bikes, I would suggest at least getting down to a local engineering shop and having some go / no go gauges made up for the various BB sizes you deal with. And get a decent set of bore gauges and a micrometer, and learn to use them, if you care about out of round issues.
You measure your BB shell, which you have already claimed to be "precision fit ...completely round", get somewhere between 45.91 and 45.92 using cheap shit chinesium calipers, and then say it's "basically exactly - it's about 45.90 all the way around". Is it in spec? Or not? Something's wrong, as PF30 specs between 45.95 and 46.00.
I can't be fagged with any more, TBH. You are right in that 99% of bike owners do not need, and will never need or benefit from, a BB like the ones Hambini makes, but given the shite that comes out of the bike industry, there are those who most certainly do, and will. Hambini's not the only maker of these type of things, either, but he offers something a lot of people don't - frame fixes that go beyond "sanding down".
4:37 & 9:01 Hambini criticized these parts of the video, he criticizes the varied thickness of the bottom bracket shell, but also the measurements, he claims the bottom brackets are way out of spec.
Not watched it yet. 😁
Tldr: There is no need to buy expensive stuff. And that counts for so, so many bicycle products with marketing bs. out there. Ceramic bearings, better brake-cable housing, 3dprinted bottle-cages, etc. Why make a complete video about one small BB brand and make a ‘commercial’ for another large brand BBB? Low volume production will alway’s be crazy expensive compared to the high volume production. It’s the Achilleshiel for true innovators. And also, the higher the price the more marginal the gain. Maybe that was a more truthful video title. (Your ‘TPU inner’ video was great b.t.w. :)..)
True. 👍🏻
you're using a caliper to do precision dimensional comparisons. 😂😂vey telling
Yes it shows that’s the tool I have to measure with. Hardly an invalidation of my argument however. But the fact you didn’t refute my argument is also “very telling.”

Good stuff as always 👍deffo wont be splashing 300£ on a bb from hambini 90£ will go great for me👍 have you came across a token ninja bb?ive seen vids recommending them just wondering was your take on those . Thanks
I have had a number of those, the screw together ones. They are all right, but overpriced imo, at £50 a pop and the Enduro bearings those come with are shite and don't last long in my experience. You will also need 2 no. custom installation spanners as the standard ht 19 notch ones are too small diameter. Token make one, as well as a company called Bitul who ship worldwide. These bottom brackets used to be installed in Look 795 Blade RS bikes if you bought a complete bike from Look, though I am not sure if this is still the case.
Also, very few people know about it, but Token manufacture versions of their bottom brackets for oversized shells too - they are 0.1mm bigger diameter than the standard.
Token yes, the ceramic bearings they use in some of them are the normal junk, but the cups/units they come in a good, if you have one just replace the bearings with something else. 🙂👍🏻

My wife gets my offloading.
I thought hambini's bb were expensive because they were carefully machined by hambini and not mass produced. It justifies his price. And I think people know that we don't have to go with his expensive bbs unless we have problematic bb shell or want marginal gains. Half a watt over 5000km was hilarious, though. The margin of error in measurement might be bigger over 5000km😅
But just put my preference straight, I would put one of hanbini bb on one of my bikes before I buy a ceramic speed derailleur pulley.
Only one issue with your comment and that is something I tried to make clear in my video. If you have something wrong with your BB shell a Hambini BB won’t fix it. The only that will fix it is if he makes you a custom solution or fixes the shell first. Hopefully that makes sense?
But yes I agree with you about ceramic speed stuff. 😁👍🏻
@@reginaldscot165 Yes. I agree with you on that. Custom bb is needed for bad bb shell.
I was just pointing out that in this bicycle industry, hambini is not the only one who sells overly priced stuff. And surprisingly enough, people buy them. And I think its better than spending on gambling, alcohol or drugs.
If you don't have a bad bb shell there's no need for a hambini or other HQ bb. If you do have an out of spec bb shell then its a top tier option.
True
The Hyundai/Mercedes analogy would be better if you said both were driving on a rough road (bad tolerance on the frame you are inserting the BB into). They both would be better, but you wouldn't really be able to tell the difference between the two because of the terrain.
Nice edit ✍️ 🙂👍🏻
6:12 it doesn't solve the issues. It will stop the spindle and BB bearings being out of true and spin freely, but instead of the inside diameter of the BB shell taking the rider weight and pedaling forces, you are now placing 100% of the forces on that face of the BB shell. Ride it for a few years and the BB ID will wallow out and the frame will become toast
You just made that up...because it's not true. If the press fit is tight, there will be NO movement to wallow out the carbon. If there was movement you will hear it.
Have you seen this happen or is it a theory? 🙂 If the BB is screwed in tight then it shouldn’t move at all.
@@reginaldscot165 you would need to tighten the BB to 400nm to not rely on the cups taking load.
Any creaking is movement, you can have movement without creaking too.
What a pointless video….
Then you missed the point. 😉
I would not buy a HBB myself, because it is not something I care deeply about. But I *do* think that there is something to be said for products that are made by a skilled crafstman who takes pride in his work and holds high standards for quality. Whether that is a bicycle frame, a pair of shoes, a piece of wooden furniture, a musical instrument or a bottom bracket. It will always be much more expensive than a mass produced item made in a sweatshop or factory in the Far East. But, it can be made to measure, you will most likely receive service for a long time and you are supporting the local economy.
I agree ☝️ 🙂
💣
Boom 💥
I am not being emotional , but i am .Do you work for cervelo.
Lol God No! 🤣
I bought one because it was simply the most expensive one I could find. Why waste money upgrading down the road by buying something cheaper, when you can just buy the best BB on the market form the get go?
Yes I don’t disagree with that logic. 🙂👍🏻
So waste money upfront, is that it?
So, "buy a Litespeed". Got it. But if you already have a bike that isn't a Litespeed, you need a Hambini or a BBInfinite one-piece, hub-style BB. The fellas at Litespeed are friends of ours, and they make fabulous products, so yes, buy one. They still buy our BB's, especially the T47 ones, simply because they, like all others in the know, realize that a hub is always superior to a conglomeration of components. This aspect is THE important takeaway here. If you have $3K worth of carbon wheels a $300 bottom bracket should not be a problem.
Great to have your input here. The main takeaway point is a $300 BB in a misaligned BB shell is not going to help you much. But that’s not a comment on the quality of the BB, it’s simply impossible for a company like yours to create a BB that works for everyone, if the frame manufacturer is not doing their job well. It’s needs fitting by someone who can negate the imperfections of the frame first.
All the best and I wish your business well! 👍🏻
@@reginaldscot165 "The main takeaway point is a $300 BB in a misaligned BB shell is not going to help you much"
I want to separate the two distinct problems mentioned above; one being frame BB shell hole misalignment, and the other being frame BB shell diameter variances .
On the first count: Let's forget about cost for a moment, if you will. If the thru-axle holes in a fork are slightly misaligned, and one installs a wheel and cinches it in, what influence does the slight hole misalignment have on the hub bearings? Granted, the wheel would not be squarely in the fork, resulting in the tire resting visually off center in the fork, or if severely misaligned, perhaps problems obtaining the proper air gap between the pads and rotor, but the wheel bearings would still perform as intended. The externalities have no influence on bearing/hub performance. The fork simply has to hold the hub and the hub goes on hubbing.
This is why the 1-piece, hub-style bottom bracket performs so well. All the frame has to do is hold onto the hub. That is all. The hub does the rest, which is why a CNC machined titanium BB shell, properly stress relieved post welding, can perform well with a cheaper plastic pressfit BB installed. The perfect bearing alignment is the key, no matter how you get there.
I realize this will always come across as talking our book seeing that we make these things. We could make anything. We could easily make thread-together BB's, which would be a lot easier to produce, but we do not, because they are clearly inferior due to the inability for anything with threads to, of itself, align halves perfectly. If the frame BB shell is already perfect, then a thread-together BB will have perfect bearing alignment simply by virtue of it "pulling" together in a perfect place.
The second problem suffered by many pressfit bikes is frame hole diameters that are out of spec, typically to the tight side. What we find particularly annoying is the refusal of bike shops to step in an fix these problems rather than bad mouthing and complaining. Bike shops all agree that chasing and facing a BSA frame is normal and necessary, yet performing virtually the same operation to correct an out of spec pressfit hole diameter is anathema. Please reread that. Yes, frame makers should be getting it right and all of that, but the ultimate responsivity for the decades-long pressfit "problem" is the abject failure of the average bike shop to simply purchase a few cutters, attach them to tools they already possess, and take 15 minutes to serve their customers. We ream pressfit bikes all of the time. It's easy. Bike shops: shame on you.
That said...
The term "out of spec" is interesting in itself simply because many frame makers have their own ideas about what the optimal pressfit diameter happens to be. Pressfit30 variants are interesting. Cervelo, for instance, is often criticized for frame BB shell problems. The truth is that Cervelo specs their fit tighter than, say, a Cannondale Pressfit30, even though they're both "designed" to use off the shelf pressfit30 products. This means that the same pressift30 cups that perform well in said Cannondale would likely be impinged and perform poorly in the Cervelo. This is why we make two separate BBRight model lines, one for Cervelo, and one for Factor, because Factor specs a fit closer to Cannondale.
I'll leave it there for now. Busy day. Forgive my typos, please.
7:30 A circle has corners?
What is a circle but a series of small straight lines… especially when looked at on a CZcams video. 😉
I own a hambini BB. Whatever your forte I’ll tell you this, BY FAR less friction, and WAY smoother than any BB I’ve owned including ceramic speed and Chris king. Do with that what you will
Yes it’s hard to say. For example the Praxis BB (cheaper than the CK or Ceramic speed) is less than 1.5 W slower than a Ham BB? So are you saying that you can “feel” that difference? I remain incredulous on that observation. Also, are you comparing the “feeling” of your new Ham BB with your Ceramic speed or CK at the end of their life? Basically comparing how a worn bb felt Vs a new one?
@@reginaldscot165 I can 100% feel it, but not while riding. There are too many factors, chain lube for example can give you watts, worn chain, anything from your feet to the tires on the tarmac can influence “feel”. The feel I am talking about is with the crank installed in the BB with nothing attached, 100% absolutely feel, and see the difference. Now if that equates to anything at the finish line I don’t know, don’t care. All I mean to say is if you want a BB smooth like butter, it’s the best I’ve seen. Even my mechanic asked me what BB it was after I had him remove it to run cables. He noticed it. That’s all I mean.
😂😂😂CLICK BAIT😂😂😂
Good 😊 👍🏻
How to get rid of creaking despite using a Alu thread together-in-the-middle BB in a carbon shell?
Prep work, check the shell shape, sanding, applying thick water proof grease to the shell, use copper grease on the threads, make sure the bearings are pressed all the way into the cups, use calcium grease on the spindle, tighten the crank arm to the correct setting, check your pedal and cleats for dirt!
Hope this helps. 🙂👍🏻
@@reginaldscot165 Hi. For aluminium threads I would use aluminium grease. Better from the galvanic view point.
First, check if interference fit is present. If you can press-fit a BB cup into the frame all the way by hand, then it's absent (it should be present). The solution for this would be to use bearing retaining compound like Vibra-Tite 530. It'll fill up any gaps still present between the BB cup and BB shell and takes 24 hours to fully cure, so it's not a process to be rushed.
@@yonglingng5640 BB barely goes in, feels like a super tight fit, no chance can get it in by hand.
Be absolutely sure it is the bb that is the source of the creaking. There can be numerous sources of creaking noise on a bicycle which all may appear to be coming from the bottom bracket area, but can be as far from it as the head set, the saddle, wheel hubs, thru axles, pedals etc. etc.
Sooo you're telling me don't buy a Lexus !! Just buy a Toyota corolla and when it breaks ! Just put a Lexus motor in it !!😢😢😅
A Lexus is a Toyota…
@reginaldscot165 Yes sir it is !! Top tier quality!! Unlike a corolla !!! I see what you are doing !! You're anti Hambini !! The Lexus of BB !! So obvious 🙄
Nice click bait on my feed.😂
Bike mechs like you and I. We know everything, no one else nows anything and we are never wrong.😂
If this weren't personal you wouldnt mention it but you spent a third of the video talking about it and repeating it.
Unlike me you've never worked in a bike factory that welds alloy, steel and ti frames. Ti Bbs are not perfect. If they are close its due to significant post weld and heat treat re processing.
A digital caliper really doesnt have the accuracy required here. Why Hambini uses bore guages and micrometers as well.
You say the 2 BBBs are the same but they are completely different in appearance and construction.
You say you dint need to spend more for better bearings. Well I say no one needs a new 10,000.00 bike because its the rider not the bike.
They could just maintain rebuild and or update their current bike like I do. With my 2009 Trance X0 gor thousands less.
Its a choice.
When you remove Hambinis custom solutions you really show your true colours on yet another personal rant about Hambini.
Without Hambini I wouldnt know you and your channel exist and neither would anyone else.
Bottom line is your bike just doesnt need a Hambini BB and this is just you taking another shot at him.
Go make your own fame stop riding Hambini's.
Not sure how it’s click bait, the title and thumbnail are 100% accurate to the video content.
Yes I stress it’s not personal because some people don’t understand that and you need to speak slowly and repeatedly to make them understand… unfortunately some people still don’t get it.
Yeah, I did say it was why I don’t need one… you really aren’t adding much to the conversation because I already made that clear in the video.
Yeah, digital callipers aren’t the most accurate tool you can use. But that’s not the point, the point is they are accurate enough, just like the BB. That was one of the main points of the video. You don’t need more accurate BBs when your shell is round.
Ti BB shells are not literally perfect, but in comparison with most PF carbon shells they might as well be.
If I’m riding Hambini’s fame you are riding his…. 😂
Same old stupid poorly thought out argument, “you shouldn’t make a video on someone more infamous than you… because it might make you more famous…” 🤦🏻♂️ So by that logic I can’t make videos about anything, can’t make a video about shimano cranks because they are more famous than me for example. Yeah I don’t think I’m going to be taking you seriously. 😉
@@reginaldscot165 I dont give two shits about adding to your dialogue.
You are full of shit. This is completely personal. The more you say it isnt the more it is.
Outting him in your title, mentioning his name constantly with on going back pedaling helps your algorythm.
When activity falls off on this you will post a follow up. Again. The conversation sees this for what it is.
Main takeaway from the video, 2 small, passionate business criticising each other. If people have 300 to spend, let them, if you put a 50 pound BB in a 5000 grand bike (as global brands do) thats worse. Help each other, not hate each other. Its silly. Trek dont care.
I’m just helping people make better choices. At the end of the day if you have the money you can spend it as you wish. 🙂👍🏻
Yes it is
ive got one , its fucking fantastic
Awesome 👏🏻
Problems with this video:
1) You say that the bottom bracket shell in the frame is completely round because the frame is hand made with a degree of pride. The relevance of this part of your video escapes me as is not the way an engineer should assess whether a bottom bracket shell is within spec. Metal frames deform at welding so there is no reason to think the shell is within tolerance without checking.
2) The Vernier calliper you used is not as accurate as using a Hambini GO NOGO tester, so perhaps you should buy one. You get readings of less than 45.95mm, which is the lower end of the tolerance for a nominally 46mm shell, though you are holding the calliper at an angle to the axis of the BB shell so you would not expect a reliable reading.
3) You squeeze the Vernier calliper when measuring the mailable plastic shell of the BB you are fitting: this is generally not what you should do. It is hard to say how much you squeeze it but with a basic Vernier calliper and a plastic shell you will probably be able to get a range of measurements by squeezing moderate amounts.
4) You assert that the metal BB shell of the frame is aligned correctly but, aside from using a Vernier calliper in a suspect fashion to measure its diameter, you provide no evidence.
5) You suggest buying plastic adapters from Ali express and say that they "look really nice". Again, not how an engineer should make a judgment on the quality of a product.
You seem fairly intent on telling people that Hambini BBs are over-priced and that we should take you word for it that other stuff is just as good in practice. Do you understand that telling people your opinions is not the same as a proper engineering assessment, which should include proper use of measuring tools? This is a harsh review of your video because that is the arena you have placed yourself in. Out of interest, are you a trained mechanical engineer?
1. if it’s made with pride then the workers would check it’s round before it’s shipped. They know more about welding Ti tubes than you and I put together. 😁
2. It’s the tool I have. There is always something better. It’s close enough to show what I’m talking about.
3. It’s very stiff plastic, needs to be as it’s pressed into the BB shell, the amount of distortion is probably less than this Vernier can measure.
4. The fact the crank can be inserted cleanly and that it spins freely. If it was misaligned (I have plenty of experience in the shop with such frames) it wouldn’t spin as well and sliding cranks In would be difficult.
5.+
They are overpriced, yes just as good, (possibly better for weight and price,) or so close you would never notice.
My opinions are also based on facts that are observable. Ham BBs have already been tested and I demonstrate that information. For example I used data from Hambinis own website.
Never claimed to be an engineer. But I don’t subscribe to the argument that people without engineering degrees can’t express opinions on such subjects. 😉
Safe riding!
@@reginaldscot165 Dear Reg, I just put a reasonable quality Vernier on a press fit BB of the type you show and its fairly easy to get a difference of around 0.05mm by moderate squeezing, so +-0.025mm. The plastic shells of such BBs are made to deform to cope with lower frame tolerances: that is one of the reasons they were introduced. A Vernier calliper costing around £80 will generally have an accuracy of round +-0.03mm, despite the graduations of 0.01mm. So +-0.055mm, or there abouts, as a measuring error. Call it +-0.05mm (proper error analysis is quite a complex statistical subject but it is normal practice to simply add a small quantity of errors together, though it may give something of an over-estimate of the error figure). The spec for a correct evo386 shell is 45.95 to 46.00mm if I remember correctly. So the measuring error is significant compared to the accuracy required to decide whether the BB unit and/or frame are within tolerance. Not good. Clearly one would hope that a frame with the Lightspeed name on it would be properly reamed and faced after welding but it is not a valid method of assessment to assume this to be the case. All products are made to cost constraints and no quality control system is 100% perfect.
Anyone is, as you say, entitled to their opinion, though the weight that others attach the that opinion may be influenced by qualifications, etc, especially if little concrete evidence is given to back up an opinion. We can can take your word for your experience and accept that your confidence in your own abilities is justified. Alternatively, you could get a more comprehensive and appropriate set of equipment and show, by proper use of said equipment, actual data related to the various parts your are assessing. This would not require you to have an engineering qualification. I would strongly recommend the Hambini GO NOGO device as a starter: they really are good. As to your laughable suggestion that the technicians at American Bicycle Group know more about building frames than I do; I do not subscribe to the argument that one must have proven experience or qualifications to be an expert and I consider myself to a highly proficient titanium frame builder. Sadly, I only have a basic MIG welder but its to tool I have and it will have to do. Best wishes, Simon.
