This is so different from the videos you make now (2021-2). You have made huge improvements!!
分かりやすいです！この動画のおかげで僕のスコットもスグにBB交換できました！！
This video has the best camera angles for this procedure 👍🏼
When I press in 24377 into those thread together BB's, I use loctite 680.
It's said that this will resolve issues where people previously encouter noise problems
Its easy when you have the right tools (and there are many much less expensive than the shimano ones, yet they still work great) and i actually dont know why so many people make a fuss about the pressfit ones. never had a problem and i also didn´t need an absurd amount of force to press them out on all frames i worked on.
How are they 4 years later when they've been changed several times? Frame getting loose yet?
Super great video, nice camera work!
BEST VIDEO ON THE INTERENET AND I'M NOT JOKING RIGHT NOW !! (no kidding, i'm rebuilding on old BMC that needs a new BB86 BB and this video told me everything I need to know! THANK YOU !)
Thanks Adam, major big help.
Your videos are great!
That brake protection paste is it used on cars caliper. Is it a silicone grease ? If yes Permatex make something similar.
What's the special sauce made of and is there an alternative to it outside of Japan?
it can be helped. by buying only threaded bbs. my second bike got one, never going back
thanks man for this tutorial, finally perfect video, I would like to replacement BB91 press-fit on my bike and this tutorial help me very well. anyway do you have any alternative "brake protector" - something similar? thanks
Thanks mate!
Sorry I don’t know of a readily available alternative to wakos I’m afraid 😔
Thanks for this video! I’m looking into a great bike that has a PF B.B. (I know nothing about it) but the reviews on PF are not good...
Thanks! In my experience, FP BBs har been fine without major problems as long as the install is made with proper tools and a proper clean of the BB shell before installation. Keeping up the bike maintenance (as in cleaning the bike regularly) should also help it working smoothly. All BB's will eventually wear out and FP ones are definitely the most cumbersome to change.
Liqui Moly Bremsen-Anti-Quietsch-Paste
equal to your paste
Very reasonable choise! I use something more universal (and cheap) like ceramic paste for car brake system like this: textar cera-tec. Generally a lot of products from car industry we can use to a bike servise - they are more cheaper than their bike equivalents!
Great video! To me it was definitely also excruciating to press it in. If you could choose freely between the different bottom brackets, which one would you go for?
Thomas Hemming Larsen thanks!
Without taking shell size, tire clearance and chain stay length into account, definitely an English threaded BB (bsa, gxp).
Best music ever 👍✌️
I did the same but only the bearing that was removed...big problem
Brake protector sauce is a silicone compound??
Enduro makes a really nice tool for this BB extraction with no hammering
There are also removal/installation kits on aliexpress for about 35-40$ , hammering can destroy carbon frames and is a prehistoric method 😂
Thank you very much!
Instead of the "brake protector", would you agree to use copper grease? it is used as anti-seize grease for example on the back of the pads of disc brakes in cars. thank you!
Since its plastic not metal, no. Use a silicone grease.
How do you guys figure out whick size you have?
Great video! Installing my first PF BB into a new carbon frame - should there be the occasional creak along the as your getting close? Had around 15mm left to go. Thanks.
A small creak can occur, as long as it doesn’t sound like cracking you should be fine. Carbon frames have tendencies to be out of tolerance it seams. If you pressing in a shimano bb86 cup you should be fine since The plastic cups seem to handle these tolerance issues better.
If you’re unsure though, take the bike to a professional mechanic.
@00:58 is that a blood and a cut at your thumb?
Nice tool
Is this Shimano SM BB71 41B?
Thank you for this helpful video. If you're looking for ideas - the world needs a 'How to remove and install a Canyon (downtube) Di2 Battery'
Noel Walsh cheers!
Thanks for the suggestion, unfortunately I don’t have the canyon anymore. I did change my battery when I had it. Basically to install it you need to remove the bottom bracket... witch is a proper pain in the ***. Just Removing the battery though, you can actually get it out at the headtube, however all the di2 cables would have to come as well... so not very practical unless you are just stripping down the frame.
That's a pity but thank you. Could you tell me please if the battery and holder come out easily enough with the BB removed? ( I think my BB is on the way out, I was thinking of upgrading my battery to try sychro shifting) Thanks again.
Yes, once you remove the two screws on the downtube you can easily pull it out trough the hole underneath the BB shell.
Hey! any chance you know what's in it or can snap a photo of the label? Hoping to find a similar type of brake grease in the US that is comparably thick and effective.
Sam Jackson sorry, I don’t have it at hand right now, this site seem to ship it outside of Japan though. (Have not verified it myself)
alexscycle.com/products/wakos-brake-protector
Just went through BB removal and took some SERIOUS violence hammering. Also hurted myself. Each time I do this kind of almost failure home mechanic things I regret it and ask myself why I just didn't bring the bike to a professional mechanic
Because they would be hitting your framr just as hard if not harder.
I find your videos really helpful! I brought a BBT9 - bottom bracket and crank arm tool (HollowTech II) and now realise I don't need it as I require a Shimano Tl-bb12 Installation Tool 160mm For Press-fit Bb to remove the Bttom bracket and Shiamno BB press tool? I've slightly new to this and limited budget aha. If anyone can help with recommendations and advice I would really appreciate it.
Ben Wilson this is a cheaper removal tool than the official Shimano one (the bb90 version fits 24mm bb’s)
amzn.to/2OKYZcH
There loads of cheap press tools as well, the cheapest way might be to just by the bearing drifts and get a rod and nuts and washers from you local hardware store.
These drifts are universal and should fit all bb standards: amzn.to/2DGECMw
Great video. You make maintenance look so easy. Where did you learn how to do it all?
Mike Chivers mostly researching online and trial and error :)
@@ridesofjapan thanks for reply, please keep making them, it helps me.🤣👍✌
Hallo! Can I use the Carbon paste for my bb86 Press fit that make a terrible noise in the Carbon shell? Thank you
I would avoid that, the small particles will probably make the noise worse as it moves under torque.
Retaining compound might be a better solution.
Question about Shimano TL-BB12 installation tool: what's the dimension of the bolt, M8 or M10 x yyy mm?!
Thank you!
Sorry mate, I don’t have this tool any more so can’t confirm.
My current press is M10 is that helps.
Thank you.
Good video
Park Tool bracket remover also helps remove the cups!? instead the Shimano remove tool.
De Witte yes, you should be able to remove the cups with the Park tool BBT-90.3 Bottom Bracket Tool Set as well. More info here: www.parktool.com/blog/repair-help/bottom-bracket-service-bb90-bb86-bb92-gxp-press-fit
i have the canyon endurace Cf 8.0 2018 model and i think have the BB72 is compartible with this?
Don’t know why canyon says bb72. The bottom bracket is bb86 non the less, just like this video. (All canyon carbon road bikes uses bb86)
Hello sir! Good video! Just one thing because i was looking for the wakos brake protector but i didn't find it. In the rakuten web's page is sold out
Javier Ros Vega try this alexscycle.com/products/wakos-brake-protector
(I have never used this site personally however)
Rides of Japan thanks. Did u ever use loctite 641 or 609?
Javier Ros Vega no, never used loctite on bb’s
Is that a canyon di2 frame? I can see it has the battery retaining screws.. Can you tell me if I can reach the battery without removing the bb?
Abhishek Purohit if you manage disconnect the from and rear mech (might be hard) you can pull out the battery trough the head tube. Will be har getting it back in however.
Dont you need a spacer between bb and crank? (Maybe its just my model, bb386evo)
kleeo83 not with this particular combination. All depends on what crank and what BB you use.
Great soundtrack😎
I have to try and get my first BB86 bottom bracket in using a homemade tool and I'm simply having the issue of getting them in straight, it's super annoying. :/
Dean Grove I think those homemade presses are one reason people have so much creaking problems with Pressfit BB’s.
At least try to get the “press adapters” that goes in the bearings, those are crucial to getting them in straight.
Something like these: amzn.to/2GyAdNs
The “rod” however, pretty much any cheap thing from the hardware store should work.
Perfect! Respect 🙏
Nice job, have you had any issues with creaking? Would it be worth the extra money to get wheels manufacturing shimano threaded-together BB?
Never had any issues with bb86
Good deal, thanks!
excellent!
If you're using brake protector a similar thing they use in preventing automotive break pads from making noise is copper paste.
Yes, I think it is called anti-squeal compound and it is widely available in auto parts stores. Don't know what it does to carbon though...
It’s is call anti seize It use on a metal to metal surface to prevent it from binding i don’t think it is necessary in this cause since the BB is of plastic/nylon. In this case I think the paste he use is a silicone grease it Is also use on car caliper guide pin it can with-stand any climate condition and does not get hard. But I don’t know the reason why you need it Maybe for easy installation and removal.
Anyone have experience using the Wakos Brake Protector for Trek BB90 bottom bracket bearing installation? Looks like a better option than retaining compound.
Mitchell Goldflies with bb90 you press the bearings directly into the shell right?
I would not put the wakos brake protector directly on the bearings, as it doesn’t harden it could work itself into the bearing if you’re unlucky.
Thanks. That is what I thought but I wanted to confirm with an expert before I screw things up.
@ridesofjapan I need your Help:
My current bikes have BSA and I love it. It's not perfekt but cheap and easy to replace the bearings!
1. trackbike Dura Ace (these bearings are so cheap for dura-ace)
2. other trackbike ceramicspeed
3. MTB sram dub
4. cx sram gxp
The problem is that my roadbike is a speci allez sprint and comes with BB30.
It's my nice weather bike but I still ride in the rain sometimes as it rains a lot here in Switzerland.
After every single ride in the rain it's noisy and I have to bring it to a bikeshop as I'm not realy confident with hammering and pressing metalbearings in a metalframe. This is a bad solution for me and I can imagine the frame does't realy like the bb30 change to often neither.
Would a BB30 to BSA adapter (cannondale/fsa/sram) be a good solution or do you recomend going for a BB30 with beather seals (kogel has crossseals for example). I would prefere to convert the frame to BSA but I know a general rule is to build bikes with as few adapters as possible.
Thank you a lot in advance for helping and keep on with your videos.
ianis
Ianis Caratti you shouldn’t be forced to change bb bearing that often in the first place I think 🤔, but I reckon the easiest way would be to get a thread-together style conversion BB, something like this wheelsmfg.com/bottom-brackets/bb30-outboard/bb30-to-outboard-bottom-bracket-for-24mm-cranks-shimano-black.html
I have a video installing a similar solution from czcams.com/video/FhZVubz0Xt0/video.html
Rides of Japan i like this idea but my crank spindle is 30mm
I checked wheelmfg bbb kcnc praxis works even chris king only makes bb30 bearings for 24mm cranks??
Not sure if I had to replace the bearing or if the sand was "just" between the adapters/spacers but anyway it is a mess and a lot of maintenance
this is the conversionkit
r2-bike.com/CANNONDALE-Adapter-BB30-zu-BSA-45g
Ianis Caratti so you’re keeping the 30mm cranks?
BSA is 24mm so you can’t install a BSA conversion adapter and still use your 30mm crank. ( if it’s not a true bb30 crank There could technically be an option out there but It would not help you in the durability department as the bearing would have to be smaller.
If the crank is a true BB30 crank then you can not use anything else than a BB30/PF30 Bottom bracket. If the cranks are wide enough for 86mm bb shells and your frame is true BB30 you and install a bb30 > 386evo bottom bracket that should be available in “tread together” version.
Rides of Japan that's new to me but bsa and 30mm works actualy check the links
r2-bike.com/ROTOR-Innenlager-BB30-BSA
r2-bike.com/HOPE-Innenlager-BSA-68-73-83-100-120-mm-fuer-30-mm-Welle
r2-bike.com/WHEELS-MFG-Innenlager-BB30-BSA
1. if you can run bb30 cranks on bsa and bb30/pf30 frames why the gxp standart?
2.if the 30mm cranks fit any frame then why create the new dub system if 50% of the old ones had the same benefits already?
3. maby sram and other mainstreambrands just want to sell more but why is chris king pushing the t47 standart as threaded solution for every spindle if bsa already is a threaded solution for every spindle!
I'm realy confused right now as you can tell...
@@ianiscaratti4924 It's a total jungle I know!
So the links you posted is for 30mm cranks in BSA frames, so that means your frame has a BSA (threaded) bottom bracket shell?
Sorry, I took for granted that you frame was a BB30 frame and you where using BB30 cranks. To start with, let's establish exactly what BB shell and what cranks you have :) Brand and model.
How many nm for the bolt mate? I never see too fast
Jose Rizaldy Carolino I haven’t found a specified torque range on the Shimano bb86... I just tighten it down until I feel there is a good amount an resistance and confirm that both cups are flush against the bb shell.
My latest install on a token ninja BB they spec it to 25-30Nm, don’t know if that helps but I wouldn’t go over that in any case.
Did the BB include spacers to install on your frame? I am trying to figure out if MTB cranks will work with a BB86 bottom bracket or if I need spacers that will space it out properly to BB92 width. Any help is greatly appreciated!
From what I remember I doesn’t include any spacers
as ive seen on gcn you dont need to put some lubricant to a carbon fiber frame pressfit bottom bracket
My shimano BB86(BB9241B) bottom bracket is marked with an L and R. I would have guessed L=left=non-drive side, and R=right=drive-side. That would mean the long half goes in drive side, the short half goes in non-drive side. But your video has it reversed. You inserted the short half into drive side. Am I mis-interpreting the video or this L/R thing?
The sleeve is not fixed to either side (on the BB I had here) and could be removed or moved to either cup before installation. (This was a few years ago so you have to forgive me for not remembering exactly)
Where can we purchase this rockin' soundtrack ?? :D
It's all free from the CZcams audio library :)
You should be able to find in in your accounts "creator studio"
Sehr gut ❤!
PRO.
Rides of Japan can you please help me i have a bike here in Japan with two bracket designs i want to remove all of the front bracket to repaint it but i don't know how if you have a idea can you help me thanks. By the way new sub keep it up
+Winston Villanueva I don’t quite understand what you mean with “two bracket designs”?
With “front bracket” do you mean racks for carrying bags?
Rides of Japan how can i send you a picture of my bike if you don't mine thanks
Sorry i mean frame if im not mistaken
Give me your email and I'll send you mine
Rides of Japan my bike is look like
Walmart Huffy 26" Rock creek mountain bike as the same of the frame
Press fit? Good luck
What even are the benefits to press fit? Seems like a big ol' pain in the bum to me
Most services using the hammer still, omg it’s like we’re still back to stone age 😂
Surprised there is no torque spec for tightening the new BB. Without torque spec, obtaining correct bearing preload is uncertain. I also know, however, the torque spec depends on the type of lubricant you use.
...and now you have your noicy bike ready
i use hambini. above 40 km hr zero creaks. in fact, faster!
You never preload those bearings before adding the crank arm...
What? The bearing preload is done with the cap that is installed after putting on the crank arm.
Hammering an carbon bike... just wait till ride mid way cracked and crashed.. good luck
I'm still surprised in this day that someone doesn't have a BB remover that doesn't involve using a mallet and scarying the living daylights out of every bike owner
Rixter haha! Agree, I’ve seen a few extractor tools for bb30 that almost work like a reverse press, but they are far and few between.
I have the type that gently push the bottom bracket out with no hammering
57chevy the dream!
57chevy what brand is it?
you still there?
I just re-watched this as it was promoted during the viewing of Hambini's latest video. Looks like he has a BB extractor that does involve and smashing (or wailing)
czcams.com/video/rtsos05Bf3U/video.html
Good luck getting that centre spacer lined upmas you push in the bearings. 9 times out of 10 it wont align. Its a poor design. Other BBs have two spacers that overlap together.
I am Terrified to do this to my Bike
In general, the SM-BB72-41 of the shimano is unthinkable! The bearing shells are very small and tighten when the bearing is mounted. The seals also generate a lot of friction. It is difficult (impossible) to achieve alignment between the two parts, especially with the instrument in the video. The grease is not suitable for the conditions of rotation (high load and low speed). It's just made to take your money!
I don't like pressfit components.
Good video , but get rid of that bloody music.... Please 🤦♂️
Who plays elevator music on such a technical video
mai lavorare a piedi nudi!!!!!!
Bro, why you working in bare feet???
Absolutely ridiculous 😔😔😔😔🤡
