Omg, self tighten??
Ha ha ha ha, idiot.
Clearly you don't understand the concept of reactive forces
Ever wondered, why it's the same with pedal threads, genius?
@@MrSuicycle I always leave pedals to self tighten with the minimum of tightening on installation. Otherwise they are a pain to get off.
(Read this in your nice voice because I'm not trying to be rude) Think about this 🤔 if you don't agree with Hambini then just clearly explain why he's wrong and why you're right. Hambini wouldn't have a channel if he called someone a wanker then asked us to like, sub, bell his five second video. People are interested in what he has to say because he'll call out a wanker then spend 45 minutes explaining in detail the design flaws and how it could be improved.
If you call someone an idiot then back it up with an explanation. If you don't think he's right I would love to hear an explanation. Trust me I love counter arguments it's how things get better.
If Hambini calls someone a wanker and doesn't explain why then he would seem like a dick. Because he explains himself he comes across as being fed up.
It looked counter-intuitive to me too, so I looked it up with Google, here is what I got:
Are bottom bracket threads backwards?
Dear Lennard,
The way the bottom bracket thread standard is, it would cause a bottom bracket cup to loosen when pedaling if a bottom bracket bearing gets too tight. It seems that if the drive-side is right-hand thread and the non-drive-side is left-hand, then the pedaling motion will not cause the cups to loosen. Did someone got it wrong originally or is there a good reason for it? Luckily bottom brackets are becoming threadless.
- Ned
Dear Ned,
Actually, the English standard bottom bracket threads are set up correctly. When the bearings are functioning properly, pedaling tightens the cups in. When the bearings are seized up, pedaling would loosen the cups.
If that’s not clear, then think about it for a moment. The drive-side cup is left-hand threaded, so if the crank were affixed to the cup like a wrench (as would happen if the bearings were seized up), pedaling forward would turn the cup clockwise, which would unscrew the left-hand-threaded cup. But if the bearing turns freely, then the spindle turning clockwise rolls the ball bearings along with it, and the outboard side of each ball turns the opposite direction of the inboard side of the ball. So, the free-rolling balls are tightening the cup in further as the rider pedals forward.
The inverse is of course true for the non-drive-side cup. And pedal threads behave the same way, even though the drive-side pedal is right-hand thread and the non-drive-side pedal is left-hand threaded.
― Lennard
"this is a rebuildable bb, not designed as a throwaway item" -- this is almost unheard of these days for any product and even people. Hats off!
The uber wonderful Phil Wood or Royce products will let you do that at a price. But you only buy once
ummm hope tech do just the bearing for their bb as well and have done well before this bb came out. plus they are super easy to replace. did my with a arm in a cast.
@@mattpeters7884 The issue with the hope bBB is that the bearings do not have a nylon/plastic sleeve and so over time they damage the crankset axle
Well, that was much less swearing than I expected 😅
Same here and feeling somewhat cheated.
Must be the new Tourettes medication.
@@colduncan1063 You do feel like you're getting ripped off :)
A little disappointed! Lol 🙂
It's evident there's no swearing because it was engineered properly ... No swearing required
my left ear enjoyed this video
*shifted the balance to the right and laughed 🤣
Righty tighty, lefty tighty. Got it.
Instructions unclear dick stuck in frame
It's still righty tighty just viewed from the other side :)
righty mighty, lefty hefty
Never listen to this lad through headphones. Intro nearly killed me.
Welcome
School boy error! Spot the new boy. 😂
Newbie alert!
you grow to love it. now jus loop it :-)
Long time no see my friend. Missed you. Whatever is preventing you from making more vids don't bother. We will be right here.
@Gabriel Trainer. Perhaps the two of you should get a room? 🤔😳
Chris Voss and then upload the results :)
@@Lestalad1961 My wife is hotter than Hambini.
@@404nobrakes Besides being a christian I am from an era where a man could greet another without being called a homosexual. But no thanks I have an amazing wife just like Hambini.
@Gabriel Trainer. A four day old slice of toast is hotter than Hambini. Right Sachin? 🤜🏻🤛🏻
Another Hambini video with no swearing. I'm scared and confused!
There is no swearing because there is nothing "shite" going on in this video
You can't swear when engineering perfection is presented in front of you.
@@Hambini I beg to differ. It's fucking marvelous 😉
@@Hambini Is this BB already sold out?
@@JMcLeodKC711 yes. It's on back order
Love it Hambini! Thing of absolute beauty. So happy to see you with another video.
bottom bracket for life , super impressed ,looking forward to the next sunday roast ,keep up the good work !
So oddly satisfying watching you work.
Very nice manufacturing there Mr Hambini. That's the way it ought to be done!
Proper 'nd easy installation of bearings - just the thing I needed.
Cheers Hambini 👍👍👌
Loving the polite format, btw 🤗
Nice Work Hambini! Enjoy your videos!
perfect timing for that new tarmac sl7!
you've won me over with this. I'm saving the video to come back to it for my future bike build
Hi Hambini, Great to know what kind of tools need to prepare, installation steps and the maintenance procedures on your bsa bottom bracket, nice video!
Loving the raw silver version. Just beautiful
Fantastic! Now I know how to install the part that will never be in stock! ;)
I purchased one of these a while back but had to put off installing because my road bike frame cracked. When I finally acquired a Waterford frame I installed it with an older Shimano 105 crank. I never knew what I was missing until I experienced the “ice on ice” level of friction of your BB. Thank you so much.
The great Hambini is a magician. He has a real job, designs bike parts, and runs a CZcams channel all at the same time.
I’m watching, commenting, and leaving a like for the algorithm
I bought a Hambini BB for my BBright bike, and it's fantastic. I definitely want one of these for my older Cervelo.
Excellent - no swearing. I'm so impressed I might buy them when my bearings are shot
Crank went straight through it. Good alignment, good fit. Fully serviceable. I will sleep well tonight.
thanks for this. done it a million times but i always learn more watching your in depth explanations. Eg i always just installed drive side first and then non. if i encounter a bike with poor alignment and wasn't paying attention that could be disastrous
Oh I like know where I'm coming for next BB well done hambini
quality work Hambini 👍🏻
it's been a while.
i thought u were sick.
i like ur vid, it's like Ramsay vids but it's about bicycle.
Nice job as usual. We are waiting for the bsa 73mm BB 🙏
Looks fabulous 👌 I want one.
So satisfying to watch.
Brilliant! bearing removal.
Beautiful piece. I also have an older Look frame that "bends" under load in very step climbs, would love it to have your bottom bracket.
I've gotten a lot of pushback by bike store managers on mentioning your bottom brackets. They know you and your channel, they keep pushing to buy big-brand BBs instead...from them, of course 😁
Your a legend. Thanks man. I'm looking up your website for parts
Very nice work and affordable.
Love to see a video on treks new threaded bottom bracket. Maybe they watched your video and made the change ;)
Looks like the best bb with the least friction ever. At least compared with your other videos. However, I will take a look at your website and order one BSA bb for my bike
Hambini...Prince of the Princess blanket!
Ready for the SL7 Tarmac 😂
Hambini my friend, I've missed you. Please keep uploading and keep up the good work.
Six minutes in, grease everywhere, "you should probably wear gloves" 🤣

I love finely engineered products. That's one of my draws to cycling. Where else can you go, where the comments are almost as entertaining as the main video content. "almost"
Practical,easy and less waste. What do the bike manufacturers get out of making things so fuckin awkward? Thanks Hambini you 5 year old princess.
Arrived in 6 days to San Diego (site said backordered) during covid. woohoo. aerospace quality. AKA, the lick.
Childish Hambino: you should make your own BB standard, it's been weeks since we have had a new "standard". I blame COVID and lazy Cannondale workers.
I recommend a metric diameter converted from British Thermal Units and 0.7mm added and a random letter. The sales feature could be the second decimal, the world needs a 78.27k mm standard. Make sure it never fits the 78.27r standard (which is NOT 78.27R) and never label it.
Oh...and make sure to use Estonian ambidextrous threading.
@@truantray XD
Nice BB and bike.
Sorry for not sending the badly/well designed YST BB I said I was going to send.. will do it this week.
Great thoroughly informative video. How does it hold up during winter riding (grit/snow/ice etc); or does it totally depend on the bearings?
Nearly as smooth as my crank👍
So beautiful 👍
nice job
I like your princess themed table
You are the first to notice this.
@@patrickharvey3847 i really dont think i am
intro greeting sound is weaker than the others. I wanted my ears to bleed :V
jk glad to have you back hambini!
different mic
Nice hyper wheels from Winspace :)
Thanks , a new 5yr vid. I have been waiting. When will Hambini threaded BB's be available in the shop?
Everyone keeps talking about the new Specialized SL7, I hope this beautiful piece of engineering finds its way onto some handmade Condor, Sarto or Legend framesets. I prefer the aluminium because it doesn’t look like a stock Shimano.
I like it.
Neat BB. Turns a threaded BB into a superior press fit BB😂
Hambini time !
I can confirm that the ring type bb cup tool is much better than the open ended. I bought a shimano open ended one around the year 2000 and it spreads when trying to remove a tight cup and slips on the cup
As your unit doesnt have O-ring seals like Shimano would 'boating grease' be more appropriate as water often gathers and condensates in BBs?
@ hambini - loving your vids and bespoke engineering insight. checking to see if you have any BBs that will interface to a 2020 Ibis Ripmo AF frame and Shimano XT groupset? believe the BB is threaded.
first time full suspension rider transitioning from a vintage hard tail mtb. still learning the ropes and will be doing a full build. planning to buy your BB install tool.
appreciate your tech consult. keep rock’n 🔥!
I’d like to use a slight film of Honda Bond.. basically a real high quality RTV. Never have to worry about it creaking and totally removable when ready to unthread.
And thats the way it should be!
Thanks, nice video, Nice BB, also is that the look bike with a back wheel in? Do tell please!
Just don’t get your channel banned. I’ll need to return to this video for the next ten years.
Everybody deserves a holiday. Some more than others. Next is the scale, ugly words and a rant! Waiting!! Rgr
I wish I had a bike worthy of such a nice BB. Maybe one day :)
My worthy frame is at the customs, arrives next week... Joined the shimano bsa waitlist in august. Today found a e-mail from yesterday, that it is on stock now. But today it is again sold out :) Damn! Joined the waitlist again.
Thank you Hambini. Look forward to my BSA BB arriving for the Aussie summer! Will rock my Hambini sticker on the frame so everyone I drop knows whats under the hood.
Darn I wished you'd offered this sooner. What difference between BB with nylon shim vs metal to metal like Wheel Manufacture, Hope, Enduro (I don't know the specific bearing number off hand). Anecdotally I always had better luck with metal to metal, including dare I admit 1st gen GXP pre-wave washer.
BTW between your video on Campy cranks and doing some digging around on Sheldon Brown page. I now absolutely now understand why threaded is an anachronisms is it was designed for cup and cone system and threads set the pre-load. The reason the cartridge Octalink and sq taper (Phil Wood, Shimano UD55) work so well as you pointed out the bearing are pressed onto the axle have superior performance. It wasn't the threading made work better those BB superior. They could have pressed in like a headset and they would have worked just as well, threading was just a convenience. I guess come down fact as long as cranks are two piece vs three piece (like DA 7700 or Ultegra 6500) all these from THM to FSA (and everything inbetween) is gonna under perform and be high maintainance
do you have a video how to install a bb when the frame has no internal threads. my carbon bike came like that and the workshop installed one. just curious
are you sure it's not a pressfit? they are usually threaded from the factory if they are bsa
@@Hambini you're correct
Nice, but I think I'll stick with the £25 Ultegra BB. Over 10k miles and still smooth.
Sounds like you have a well-aligned frame so off the shelf BBs will work well for you. Think the Hambini product is more for frames with imperfect alignment **edit for clarification** from play in the threads.
@@olisharp6801 That might be true for the classic hambini BBs (for PressFit), but like he says in this video: his threaded BB demands very accurate alignment, otherwise the two parts won't fit together when threading in the cups. So these BSA cups from Hambini won't work in shitty frames.
Oli Sharp If you want your bearings to work right and last very long with this type of design, the threads and faces of the shell must be properly manufactured and prepped in a professional manner. EVERY 'professional' shop has the proper tools to make this happen, (just not always the expertise!) but they CANNOT SOLVE poor manufacturing and QC issues at the factory level. This is the same problem as with Pressfit shit which can never ever be made right with current production procedures!! These frame prep procedures I mentioned ENSURES ALIGNMENT or proves a lack of manufacturing quality. These are things that ought to be done when the bike is assembled at the factory, but very rarely is, due to greed and the bottom line! Often, even on high end bikes!
High quality, perfect and long lasting threaded BBs have existed for decades! Just about as long as bicycles have existed. I own many examples. If you want to see an example of old school perfect loose ball BBs, look at a Sugino Superlap BB in an NJS qualified track bike. Hell, I have an ancient Raliegh with a loose ball cottered bb that spins smoother and quieter than lots of the pressfit shit I come across!
Hambini's unit doesn't 'improve' alignment of the shell!!! There is no difference (function wise) between Hambini's and a Shimano bb aside from the bearings used and the serviceability. Can you not see this? How many bearing assemblies have you installed? Am I the only machinist and mechanic who comments here? Gee Whiz!
I was thinking about the return to threaded BBs that has started with the likes of Trek. They have gone all the way back to an aluminium tube bonded into the BB that cups thread into. Why didn't they make a aluminium tube that bearings can press directly into, essentially like Hambini's BB here and just bond it into the BB shell?
This one is made to replace a HollowTechII BB so the bearings are external to the frame. If someone was designing from scratch they might make it a single part where the external surface is a plain tube and just have internal ridges that the bearings press against. It could be as wide as a current pressfit BB and whatever diameter the frame allows. Is any more required than that?
I just bought a Cervelo bike. The Aspera. With the proprietary Cervelo BB. I’ll probably regret it. Damn.
Don't worry. We'll see reaming of your bike by 5 yr old Frenchie soon on this channel.
I’ve been riding my aspero for a while and it has been trouble free. I’m an independant bike mechanic and I’m pleased with the fit and finish.
Get a Hambini BB
@@404nobrakes it won't fit coz the concentricity is shite
Frederic A. Truslow just use a stronger press and ream the f*ck out of the frame
Nice work Hambini. Hey I’ve got a video idea for you. The new rapide clx wheelset from Roval. 35mm external width in the front wheel with 26c tyres. Love to get the real story on those aerodynamics 😳. Not sure what the best forum or location would be to make the request so I’ve put it here.
would you recomend this bb for mtb use?
@hambini Have a look at the new enve tyres in your Sunday roundup
Could you make a 30mm spindle version of this please?
Pedaling forward could loosen the BB if not fully tightened as you tightened the BB while "pedaling" backwards, same with the pedals I believe the reason for the reverse threads is that BB's and pedals don't become too tight after time. am I misunderstanding??
Would you ever sell delrin go/no go gauges for us to quickly check new frames for being roughly within spec before building up?
Muy educado hoy !!
I wish this product was available 2 months ago. I got some Rotor BSA cups, removed the cheap bearings and installed some nice Hambini NTN 6806 bearings (386EVO crank on BB30 shell). Which got me thinking, will the removal and installation of bearings eventually wear the fit in the cups?
Tony Diez probably. It’s alloy vs hardened steel. But would you rather wear out a $250 BB (which includes bearings) or your $3000 frame? The Hambini approach is so much better than any other BB implementation that it kind of boggles the mind. How is this not the industry standard
How can we help reduce the price? Coz man, I haven't yet replaced even 10 bottom brackets though my whole cycling life...
what year is it? So nostalgic, a retro Hambini video here
I have been looking at icancycling's frame set. but was wondering how they stack up to the likes of yoeleo frames
Like watching an artist at work😅
Would you consider a campag BSA bb?
Hi Hambini! What are your thoughts on cage bearings against loose bearings for a BB application?? The other day i did a maintenance on my BB and i replaced the caged bearing for loose balls, and now they seem to work better than with the caged ones, but maybe they will need more frequent maintenance, idk
That standard must be back nowadays (built to last and not to throw) you have a great potential Hambini in the cycling industry. By the way, do you have bb for mtb?
If you wanted to only use bearings without a seal, could you make a replacement dust cap that has an o-ring?
Hey Mumbai, next time you are installing a BB take a small file or 80 grit sand paper to that "paint over-spray" rim area on the frame prior to install.
Brilliant! Have something on GXP Italian threaded? 😬
Couldn’t you make a thread-together bsa bb? Like screw the drive side and then screw the nds in both the bb shell and the drive side?
I didn't know you made BSA bottom bracket?!!
I wonder if I can use this on my brompton
I like the design detail in ur BB. would be nice if there was a stockist.
In the long run does the bb make noise on bumbs? Because they'll hit each other? Curious or it's time to service it maybe
Nice job, black looks good. I recognize the wheels :) Got to get my hands on some...
They are very very fast. I'm going to do a dedicated review on them. Fastest wheels of that depth.
@@Hambini Even with external spoke nipples? Is that last single watt of aero savings not attractive enough?
Edit: are we going to ignore the fact that they come with ceramic bearings, and Hambini is still touting them as the "lick"? XD
Hambini im pestering joe to find me a set for a gander. Will have to bolt ye olde discy breaks to them tho.
name please. :)
@@wsnx_ I think they want to keep it secret until a certain date. At least I'm not going to be the one to spoil it.
Value wise, that BB would get you 176.6 portions of mushroom bhaji from the Kashmir in Bradford.
You'll climb better out of Bradford over to Shipley or Keighley with the bb as opposed to the bhaji.
@@markrushton1516 I'm living over in Norway now and know exactly what you mean. Could still murder a meal or 176.6 from the Kashmir though :D
Have a few veg dhals too and you may have a gas powered bike with a BB that's stiff as owt
It could psychosis brought on by lockdown, but didn't you procure a nice bit of Italian crank hardware for the Look aero build?
