Nice video, very clear on all fronts. We did notice that you are pressing on the inner race of the bearing rather than the outer race. We believe it is best to interface with the outer race only, as it is not part of the rotating assembly. When pressing against the inner race the inner race engages the ball bearings and pushes them into a bind against the outer race. This action frequently puts indentations in the races that lead to premature failure and if severe enough, an indexed "feel" to the bearings right after the install is done. Love those purple cranks!
Thanks for the feedback. After having done this a couple times, I'm thinking of going with your product. This fix seems to wear out after a few weeks, especially if any rides are wet. I'll let you know!
We'd be stoked if you rode our product. I was hesitant to comment on your vid because everything else you did was spot on if one is sticking with running the bike in a stock set up, bearings in frame, all that. Whenever someone posts a technical explanation/process vid on RUclips there's a great deal of courage involved as the techno trolls invariably crawl out of the woodwork to correct the slightest thing. We salute you.
Man. I'm disappointed. I just talked to my local bike shop, and the mechanic told me BBInfinite was a tough fit for C-dale Slates because of the internal cable routing through the bottom bracket. Tough problem. I hope you guys can come up with a solution. Thanks again for reaching out.
Yeah, the Slate's internal hydraulic cable makes it a very tough fit. You'd have to pull the line, install the bb, then fish the line back through, bleed it, and go. We do it all the time but for some people it's just too much work.
Since people wonder, here's some history on press-fit BBs, from what I can find. They were developed by Cannondale in 2006 when CAD and computerized specs reached a level they felt was high enough to prevent error (yes, many people will tell you they were dead wrong). The advantages of a PFBB is that they are lighter than a threaded BB assembly because of the elimination of separate bearing cups, and stiffer due to a 30 mm diameter spindle. They also have more room in the bottom bracket area to attach larger down tubes, seat tubes, and chain stays; and because the shell and spindle increase in diameter and not width, the cranks can be made to provide more heel clearance. I don't have ledgers in front of me, but I believe they are cheaper to manufacture as well. In 2010 Cervélo changed things by creating their BBright, an asymmetric bottom bracket system, adding another layer of complexity. Around this time, the vast majority of all bike manufactures adopted PFBB's. The negatives of PFBBs are because they demand that the opening on the frame must be absolutely precise, and most PFBB's contain plastic parts, they are prone to leaking, creaking, and wearing out. Some third party manufactures such as Chris King and Legit Engineering jumped on this and made metal PFBB's that eliminated the creaking (for the most part), but that still relies on the frame being incredibly precise. Plus being all metal, adds weight. They are also harder to service, and replace than a threaded BB.
Unless your bearing fits very loosely in the frame, the Loctite adhesive really doesn't address what causes BB30's to creak. From my experience, it's the spindle to bearing interface that creaks, not the bearing to frame interface. Look at any spindle that's been used for a period of time. There's always witness marks on the spindle where it walks around within the bearings. Yours is visible about the 6:47 point in the video. The best solution I've found is to ditch the wavy washer and stack just the right amount of spacer shims in it's place. I made a video on how to do so. Sometimes the spider (or in your case the 1 piece chainring) bolted to the crank arm can creak as a seperate issue. The Loctite 641 works really well on the spider splines and the lockring to keep this area quiet.
I use a spoon full of penetrating oil inside the housing. Keeps everything lubricated better than grease. Simple, you wouldnt put a motor cycle together without oil in the crankcase.
After checking my bike thoroughly I still had a creak, eventually traced it to the bolts for the cleats on my shoes. I put on some grease and tightened the bolts, creak gone‼️👍
You never want to press a bearing in by pushing on the inner race. Good way to wreck the bearing. Use a drift that presses against the outer race. Cannondale also makes a tool that is specific to removing hollowgram cranks. It threads into the axle, then you can use a standard park crank puller for splined axles. You got away with some stuff there. Lucky nothing was damaged.
Thank you so much for posting. I was going crazy trying to figure out where the creak was coming from on my Cannondale Slate Ultegra. Worked like a charm.
You may have damaged the bearing by pressing on inner race, you should have pressed on the outer race. Beside that BB30 is a POS. Who was engineer who designed this scrap?
I’m replacing bb bearings on my 2012 Supersix Evo hi mod. It has a sram PF30 as stock when i got tge bike brand new. So i’m gonna replace it and use the same brand PF30. In this case carbon to plastic shell cup. What loctite should i use for this?
Yes. my 2012 trek fuel has press-fit, but no creaking and good bb life. The 2016 Remedy, however is not so. The first set lasted 6 months and when I removed them, the left side pulled out easily with my fingers. The new unit dropped in so easily that I was compelled to use loctite. One year later? Creaking.
I have a new Supersix Evo, BB creak started 1 week after I got caught in the rain, isolated to BB by removing chain and notice as start to move crank, watched this video, decided to remove seat post and just poured a little engine oil down inside to allow to drip around the BB, angling the bike left then right whilst turning the cranks to allow penetrate and drip out slowly underneath onto a rag. Creak has stopped. Never tried or thought of doing this before but creak only came after the rain and this has done the job - was going to WD40 it inside but decided to try engine oil.
Love it. Will try it. Nothing to lose. Reminds me of old internal hub shift mechanisms that had an oil input cap. Used to squirt oil right in there. Method described here unsuccessful.
cannondale makes a bb30 to bsa conversion tube. Press this in with strong locktite and enjoy your creakfree bsa frame. btw bsa fits any crank yes even bb30 ones
Go to hambini and order his bottom bracket. He can barely keep them in stock because they work so well. He is an aerospace engineer and knows what the hell he is talking about when it comes to bearings. Your welcome
Why is it that so many garage mechanics think they can wrench when they don't even understand proper function of a simple bearing? Please, leave it to the professionals or continue throwing your money away! Even many bike shop mechanics don't understand this because they have little experience or expertise with machinery. The bearings themselves are not the cause of all the problems caused by press shit designs. The worn and noisy bearings are the symptom and the result! The issue is the holes the bearings are pressed into. The molded bottom bracket shell. It is their inaccurate sizing, inaccurate roundness and non-concentricity. Even mass produced cheap Chinese bearings are manufactured to fairly accurate dimensions. Ive built and installed countless fine bearing assemblies in surgical devices, aircraft and spacecraft. Plenty of other expensive machinery as well. Ive helped build carbon structures used in satellites. I was also a mechanical inspector. I know how it's supposed to be done. Ive worked to the highest levels of quality, reliability and human safety on the planet. Now I'm retired and wrench in a high end bike shop. Ive seen the numerous and constant noise, unacceptable wear, fit issues and all the numerous changes to this absolutely poor design. I wonder why? We never had all these issues with threaded designs.....So I get out my precision measurement instruments to investigate why there's so many problems. Ive now measured over 100 BB shells. Not one was manufactured per engineering specifications! Some were not as bad and some were so bad you could visually see the discrepancies with the naked eye! What sort of joke is this when bearing tolerances are commonly measured in tenths of thousandths of an inch? Per bearing manufacturers that is!! Again, not one press shit BB shell met commonly accepted engineering STANDARDS. There are now dozens and dozens of bottom bracket 'standards'. Does anyone actually realize what a manufacturing standard is?? I hear noisy bikes roll in and have come to assume they're a 'Creakenfail' because very often they are some of the very worst. Didn't 'Creakenfail' bring us BB30? Didn't 'Creakenfail' have some very serious safety issues with headset bearings fairly recently? That was sort of a well kept industry secret! If you actually listen to Hambini and are capable of understanding what he talks about you might realize he's an experienced engineer unlike MANY so called 'engineers' in the bike industry. Please use (not so) common sense. How could you ever understand what an engineer talks about if that's not your particular 'expertise'? Talented engineers never stay in the bike industry for long. It can never pay enough. I wrench in bikes because I love bikes and helping people. I don't need the money, but pro deals support my habits. If you look at Hambini's bottom bracket design, you just might understand why it works, how it solves the regrettable problems and how it is superior to most of what is out there. Several pro teams are using his designs. If you understood bearing applications and the ultra precision tolerances that are required for their proper operation and normal service life you would understand that press shit frames are an utterly poor design. This is information that bearing manufacturers provide and its available in engineering resources. I know exactly where to find it. I can easily prove that manufacturers of press shit ignore said information for their profit. If you understood the greed of the larger bike industry, their compromise and the way they manufacture these poor excuses for bottom bracket shells among MANY other aspects, EVEN SAFETY RELATED, you might realize even all these fixes for the unknowing consumer are mere bandaids for a shit design.
@@Ih8GoogleandApple Yup. I buy things that can be made to last for decades like custom built frames to MY specs. Not one issue with the several metal frames I've had built in 40 years of hardcore riding and racing. Ive got bearing components that are decades old such as Chris King and Campagnolo, even Shimano , which use angular contact bearings which can be adjusted snd serviced for much longer life. Excellent quality stuff still exists. If you are serious about equipment and keeping it for a really long time the extra investment is an excellent value. If people actually ignore marketing BS and educated themselves in regards to their purchase decisions they might be more content. I am not proud to say I can't trust my chosen industry. I get in hot water for discussing truth at work sometimes. I don't care about the sale! I just want folks to be happy and ride more. I need to look at myself in the mirror every single day!!
looks like you did a great well thought out job.. Im have the same creaking issues with my bb30 external bottom bracket and I've heard of this method but was reluctant to try it. I have a question when did you pack the bearing with grease? or didn't you?
Thanks! BB30 creaking is so annoying. The bearings are sealed, so there's no packing them. I do recommend putting a layer of grease on the spindle before it's re-inserted into the bearings, though. My experience with this method has been that it drastically reduces creaking, but that I still get a click when I really crank the pedals, like standing to sprint or climbing.
thank you. yes after I take it all apart clean everything and grease everything back the creaking does stop for a time. however it comes back after a while. when I stand on the pedals its much more pronounced How did you bb30 function after applying loctite?
The loctite significantly increases the amount of time until you hear clicking again. It's a good fix for folks who like doing routine maintenance. If you hate maintenance, you might be better off going with a Hambini or Praxis bottom bracket insert. Unfortunately, you can't use hollowgram cranks with those options, so it gets expensive in a hurry when you change out cranks.
Nice video, really straight forward. Everythink clearly explained. Keep it up. One question though - what drivetrain setup do U use ? I mean how many cogs and theeths in rear hub and how many teethes in front crank arm ?
Any decent mechanic (of any machinery) KNOWS you install cartridge bearings by pressing on the outer race. Doing otherwise damages the bearing immediately. How many cyclists actually realize how precise a bearing assembly really is?? How many cyclists ignore their bearings until it's too late? Oh! They're too messy and complicated! Dont riders understand we roll around on this junk?? Look at bearing tolerances in engineering literature!! Ive watched you tube how to videos where idiots hammered their bearings in. Forrest was right, "stupid IS as stupid DOES"
Nice n precise video thanks! I have a cannondale caadx cx bike. I had a similar problem but the bearings came out whilst ridding one day! Took it back to the shop n they used lock tight 681 will i be able to service it myself and replace the bearings?? 👊🏻😎👊🏻😎
Hi Jon, Loctite 680 is pretty tough stuff, but I believe adhered parts can be removed, carefully, with the right tools. I'd run the question by your LBS before I went banging away on anything. Good luck!
Thanks for being so detailed. So, what actually causes the creaking? Mine is so loud, it sounds like my bearings are being destroyed. Did you replace the bearing cases with new ones or did you just wipe things off and degrease things?
hi, i've tried with the green locktite for cylindric parts, put a little on the outer side of the bearing but also on the inner side of the bearing, instead of putting grease, i must say its a bit better but still creaking when i push verry hard. think i have to look furder for a better solution, thanks for the video!
I was a machinist for 30 years. Now I wrench in a shop. Realistically you can never get good bearing fit or operation in a frame that has not had the bearing bores machined. Most carbon frames are molded. Very few are machined. For a bearing to work properly and live a full service life, the bore MUST! be machined to tolerances of tenths of thousandths of an inch. If the bore isnt perfectly round you distort the bearing. You can put a brand new ceramic bearing in a molded frame and it will feel rough as hell. Loctite, epoxy etc are just bandaids. The only solution is to use a collet type BB such as Praxis. This is basic manufacturing design and bike manufacturers who employ these designs are irresponsible money grubbers or employ piss poor engineers. If you dont believe me read a machinery handbook. Stay with threaded bb shells or tolerate shitty bearings.
This is interesting and might explain why Chris King says their PF BB's are guaranteed to last, even outlast a few bikes. But the fine type notes that this theory relies on your bike people properly molded.
Phil Anderson if the hole isnt round something has to give ; either the bearing or if bearing cups are metal then frame will distort to accept cups. Neither is optimal. Especially not on high end frames!! Nothings wrong with threaded designs! PRESS FIT IS MERELY MARKETING BULLSHIT!!
twosence fromcleveland santa cruz uses threaded. Specialized does on some models If consumers stop buying the crap they are forced to accept then suppliers will conform or die.
Nice video. Lots of good comments (must use correct press adaptors that rest on outer race) and lots of inappropriate comments (since is BB30 the shell is aluminium, so the comments about PF30 / carbon shell, don’t apply here). Point is, original BB30 is already a machined metal tube. The later PF30 versions are the ones that have the most problems. That said, maintain all press fit BBs at least annually and keep them clean or suffer the creak
Put the crank spindle in the freezer for about an hour … it will contract and make it slide right on in. This will ensure the bearings are not disturbed while the loctite is curing
You forgot the 2 shims that you took out. Im sticking to my Derosa’s old technology that still works,,, im not going to win the Tour de france anyway...
My bb30 was a POS!! 😐 Tried everything. BBinfinite didnt fit because of the di2 cables. I sold my fancy SISL2 cranks and picked up a 9100 dura ace and converted it. I still have flashback of the creak on my old sprints
Excellent video Sir Double Arrow, made all the necessary relevant points. Doing the best you can with a compromised situation. Robert Trageser below says it best, his comment is spot on. We the consumers need to stop buying the manufactures crap no matter how tempting. And twosence fromcleveland you're gonna have to keep shopping for the frame that meets your needs and has a threaded BB to boot, or perpetuate this irresponsible manufacturing mayhem. You can spend 5 G's on a frame and it's very foundation is compromised from the beginning, ludicrous! It's not the spindle interface that is the issue, (Joey Mesa). If the interface between the frame and BB bearings were correct, (proper materials used, concentricity, and bearing clearances) the spindle interface becomes a non-issue. It's rocket science!
Hi John-Great question. Grease won't work, unfortunately. The bearings need to fit tightly into the BB shell and stay put. If you use loctite, be sure to use a product that won't glue the bearings in for good. Use a product specific for bearing fit. This is a frustrating problem.
I use a spoon full of penetrating oil inside the housing. Keeps everything lubricated better than grease. Simple, you wouldnt put a motor cycle together without oil in the crankcase.
thought this was a great until i worked out that retaining compound (anaerobic adhesives) weakens carbon fibre (pva or peo glue). Swap bb30 to Hollowtech/ bb86 if you dont want the noise
i think i have a bb86 or 90. I lubbed the spindle and cleaned everything and that worked last time. This time i took out the bearings and pressed them in ok and the creak is gone. But i messed up the sleeve. It has two o-rings and i dont think i lined it up right, either when it was pressed or when i pushed the spindle in. It wouldn't go in so i rubber hammered it a little. A little too much. So i am running without this plastic sleeve. Does this just protect the spindle from water and dirt or is there some kind of pressure to keep the bearings apart?
Very clear, concise, to the point. You are a very good communicator and knowledgeable of the trade, however from the engineering side, the designers and companies that allowed that bad joke called bb30 press fit in carbon, should be hang by their bb's
Great question. Loctite 242 is a straight-up threadlocker. Loctite 641 is a retaining compound specifically for cylindrical bonding (i.e., bearing fit). It is medium-strength, meaning it's good for parts where disassembly might be required periodically for service.
Looks like most of the big companies are switching back to threaded BB. Specialized dumped it this year on their FS Bikes and using threaded BB. Press fit was a joke on the lower end bikes.
Man, that's so frustrating. Sorry to hear it. I share your BB30 frustrations. I've discovered with some trial and error that cleaning the outside of the bearings and the inside of the BB shell with an aerosol degreaser results in a better bond and makes the solution last longer.
Buy properly designed frames! Press fit MUST be machined. Stay with threaded shells. Everything else is marketing drivel. Otherwise, tolerate your incessantly creaking BBs to enjoy a questionably stiffer crank! Even if it stops creaking it will come back and bearings will wear out quicker. But go ahead and splurge on those $100 bearings!! The bike industry loves your ignorance!!
If you have a creek on your BB30 bike, look for Hambini here on RUclips. He’s an engineer that makes one piece bottom brackets for all bb30 systems and they’re manufactured to aerospace engineering tolerances. They make every and all creaks go away.
Wrong press = you damaged your bearings. You had to push the outer and inner rings at the same time to prevent damage to the inner surface. If you only push from the inner ring, the power you put on is transferred to the outer through the balls. This creates too much pressure on the contact of balls and races and causes eventually damaged points inside the race. Your bearing will then not run on a smooth surface and take more damage in every turn. This will lower your bearings lifetime and cost you watts.
I worked at FSA for two and a half years. While there myself and a coworker experimented with different compounds to see what lasted the longest in preventing the creaking from coming back. We found that Locktite 480 worked excellent and lasted longer. It has a holding capacity almost identical to 242 but has components in it that make it feel like rubber when dry and it actually expands. So it does not break free as soon as the 242. Also when used with a press fit plastic cup in a carbon frame it expands and forms into a rubbery material to fill voids between the bearing case and frame as carbon layups are not perfect. It does not hold so great as to be a detriment when trying to remove a worn out bearing.
You want to eliminate that annoying creak get yourself some earbuds and listen to some good House music. You won't hear the creaking and the beat will help your cadence and motivate you to ride harder. It worked for me.
@@skcyclist Why not? Everybody using the roads drives distracted. I see people in group rides texting even. It's all a game of chance the way I see it. You truly want to be safe stick to the trails and off the roads. No matter if you're wearing earbuds or not, you are not safe on the roads.
@@charlesmansplaining it's not safe, that's true, but I want all my faculties tuned in to potential threats. You and others are welcome to do as they please.
I would never press a bearing in by the inner ring. I would think you're going to damage the new bearing. Sure bang out the old bearing from the inner ring...but I would only press the new bearing in from the outer ring. If I saw a shop do what you just did...I would walk out of there and never go back.
Oh yeah 😎. OR? Rent a "Blind Bearing Puller", from AutoZone. Used to remove the pilot Bearings or pilot Bushings from the Flywheel that transmission shaft Rests/rotates on allowing Flywheel and transmission to turn together. Insert one hook 🪝and hook the inside of Bearing/Bushing 🪝with the Bearing Puller and Jerk the slide Hammer 🔨 away from Bearing and pop that puppy 🐶 right out.😄
I'm afraid you're wrong. The creaking is caused by the bb axle fretting inside the inner race, not by the bearings moving in the frame. Look for blueing of the grease on the axle as evidence as well as signs of wear where the axle sits inside the races. Simply refit the axle with a smear of bearing fit compound to cure the creak.
WTF!!!! Pressing on the inside of the bearing??? That's why Press fit are a joke, people dont know how to handle it... And Bike manufacturer cant keep the tight tolerance, that is needed for a correct fit.
Misalignment issue on canondales major issue engineering wise a 5 year old could do better. Total missing point off the problem ignoring this instead get a real understanding of what going on and real emotion at hanbini . Com

Do not pour oil inside your carbon frame, it will delaminate.

This is information that bearing manufacturers provide and its available in engineering resources. I know exactly where to find it. I can easily prove that manufacturers of press shit ignore said information for their profit. If you understood the greed of the larger bike industry, their compromise and the way they manufacture these poor excuses for bottom bracket shells among MANY other aspects, EVEN SAFETY RELATED, you might realize even all these fixes for the unknowing consumer are mere bandaids for a shit design.
Damn good rebuttal Rollin Rat! Bikes are now made to be disposable which is why I love custom hand made bikes that are made to last!
@@Ih8GoogleandApple Yup. I buy things that can be made to last for decades like custom built frames to MY specs. Not one issue with the several metal frames I've had built in 40 years of hardcore riding and racing. Ive got bearing components that are decades old such as Chris King and Campagnolo, even Shimano , which use angular contact bearings which can be adjusted snd serviced for much longer life. Excellent quality stuff still exists. If you are serious about equipment and keeping it for a really long time the extra investment is an excellent value. If people actually ignore marketing BS and educated themselves in regards to their purchase decisions they might be more content. I am not
proud to say I can't trust my chosen industry. I get in hot water for discussing truth at work sometimes. I don't care about the sale! I just want folks to be happy and ride more. I need to look at myself in the mirror every single day!!
Just remember. If your shell is carbon use activator. Or the compound will never set properly
Loctite 7471! :-)
Sir, is there not a physical metal or plastic bracket that the bearings fit into? Or are the bearings set directly into the frame?
looks like you did a great well thought out job..
Im have the same creaking issues with my bb30 external bottom bracket and I've heard of this method but was reluctant to try it.
I have a question when did you pack the bearing with grease? or didn't you?
Thanks! BB30 creaking is so annoying. The bearings are sealed, so there's no packing them. I do recommend putting a layer of grease on the spindle before it's re-inserted into the bearings, though. My experience with this method has been that it drastically reduces creaking, but that I still get a click when I really crank the pedals, like standing to sprint or climbing.
thank you. yes after I take it all apart clean everything and grease everything back the creaking does stop for a time. however it comes back after a while. when I stand on the pedals its much more pronounced
How did you bb30 function after applying loctite?
The loctite significantly increases the amount of time until you hear clicking again. It's a good fix for folks who like doing routine maintenance. If you hate maintenance, you might be better off going with a Hambini or Praxis bottom bracket insert. Unfortunately, you can't use hollowgram cranks with those options, so it gets expensive in a hurry when you change out cranks.
I have and have always had a praxis works bb30 with external bearings. they creak
Man. There's no winning with these things sometimes.
Thanks for the video. Whats an accelerant? I have supersix evo. Carbon.
Yes, I'd love to know what accelerant to use...
Nice video, really straight forward. Everythink clearly explained. Keep it up. One question though - what drivetrain setup do U use ? I mean how many cogs and theeths in rear hub and how many teethes in front crank arm ?
Thanks Carlos. It's had some replacement parts, but still essentially stock: Cannondale 44T chainring, SRAM X1 11-speed cassette, 10-42T.
The adapter is wrong. You only press on the inside of the bearing. It is already Damages slightly
Any decent mechanic (of any machinery) KNOWS you install cartridge bearings by pressing on the outer race. Doing otherwise damages the bearing immediately.
How many cyclists actually realize how precise a bearing assembly really is??
How many cyclists ignore their bearings until it's too late? Oh! They're too messy and complicated! Dont riders understand we roll around on this junk??
Look at bearing tolerances in engineering literature!!
Ive watched you tube how to videos where idiots hammered their bearings in. Forrest was right, "stupid IS as stupid DOES"
You have a very cool looking bike. Cannondale slate. I do hope you can do a review on the bike . Cheers!
Thanks! I like the bike a lot. I'd like it more if Cannondale would go back to threaded bottom brackets, though.
Hi yea.. I'm riding a cannondale fsi but somehow I'm lucky no issues with bb30.. I hope u can do a review on your slate.. Cheers!
Nice n precise video thanks! I have a cannondale caadx cx bike. I had a similar problem but the bearings came out whilst ridding one day! Took it back to the shop n they used lock tight 681 will i be able to service it myself and replace the bearings?? 👊🏻😎👊🏻😎
Hi Jon,
Loctite 680 is pretty tough stuff, but I believe adhered parts can be removed, carefully, with the right tools. I'd run the question by your LBS before I went banging away on anything. Good luck!
Double Arrow Metabolism -frame could easily be damaged then! 😱😱
Thanks for being so detailed. So, what actually causes the creaking? Mine is so loud, it sounds like my bearings are being destroyed. Did you replace the bearing cases with new ones or did you just wipe things off and degrease things?
That’s because your bearings are snagged - nothing to do with BB30
What kind of lubricant did you use on the spindle?
Can I use Loctite 648 instead of Loctite 641?
Hello, Thanks for the great informative video. Do you know if this 641 retaining compound product can be stored for years if not used after opening ?
$20/set of Chinese ceramic bearings plus 50c worth of penetrating oil and two years and 20,000 klms later it runs as sweet as a bought one lol.
hi, i've tried with the green locktite for cylindric parts, put a little on the outer side of the bearing but also on the inner side of the bearing, instead of putting grease, i must say its a bit better but still creaking when i push verry hard. think i have to look furder for a better solution, thanks for the video!
I was a machinist for 30 years. Now I wrench in a shop. Realistically you can never get good bearing fit or operation in a frame that has not had the bearing bores machined. Most carbon frames are molded. Very few are machined. For a bearing to work properly and live a full service life, the bore MUST! be machined to tolerances of tenths of thousandths of an inch. If the bore isnt perfectly round you distort the bearing. You can put a brand new ceramic bearing in a molded frame and it will feel rough as hell. Loctite, epoxy etc are just bandaids. The only solution is to use a collet type BB such as Praxis. This is basic manufacturing design and bike manufacturers who employ these designs are irresponsible money grubbers or employ piss poor engineers. If you dont believe me read a machinery handbook. Stay with threaded bb shells or tolerate shitty bearings.
This is interesting and might explain why Chris King says their PF BB's are guaranteed to last, even outlast a few bikes. But the fine type notes that this theory relies on your bike people properly molded.
Phil Anderson if the hole isnt round something has to give ; either the bearing or if bearing cups are metal then frame will distort to accept cups. Neither is optimal. Especially not on high end frames!! Nothings wrong with threaded designs! PRESS FIT IS MERELY MARKETING
BULLSHIT!!
Very good, Robert, but this practice is so wide-spread, it is difficult to find the bike you want without this unfortunate design.
2019 Specialized Stumpjumper brought back the threaded BB.
twosence fromcleveland santa cruz uses threaded. Specialized does on some models If consumers stop buying the crap they are forced to accept then suppliers will conform or die.
any pics of the bike?
I can’t believe someone hasn’t asked you for a new crank after showing that driveside crank removal method.
Nice video. Lots of good comments (must use correct press adaptors that rest on outer race) and lots of inappropriate comments (since is BB30 the shell is aluminium, so the comments about PF30 / carbon shell, don’t apply here). Point is, original BB30 is already a machined metal tube. The later PF30 versions are the ones that have the most problems. That said, maintain all press fit BBs at least annually and keep them clean or suffer the creak
And all this hussle when we already had threaded BBs... thanks for nothing cannondale
can hollowtech install to that?
Put the crank spindle in the freezer for about an hour … it will contract and make it slide right on in. This will ensure the bearings are not disturbed while the loctite is curing
Isn’t that “bolt” the self-extracting locking nut?
youre using the wrong size bearnig press bit
You forgot the 2 shims that you took out. Im sticking to my Derosa’s old technology that still works,,, im not going to win the Tour de france anyway...
My bb30 was a POS!! 😐 Tried everything. BBinfinite didnt fit because of the di2 cables. I sold my fancy SISL2 cranks and picked up a 9100 dura ace and converted it.
I still have flashback of the creak on my old sprints
Excellent video Sir Double Arrow, made all the necessary relevant points. Doing the best you can with a compromised situation. Robert Trageser below says it best, his comment is spot on. We the consumers need to stop buying the manufactures crap no matter how tempting. And twosence fromcleveland you're gonna have to keep shopping for the frame that meets your needs and has a threaded BB to boot, or perpetuate this irresponsible manufacturing mayhem. You can spend 5 G's on a frame and it's very foundation is compromised from the beginning, ludicrous! It's not the spindle interface that is the issue, (Joey Mesa). If the interface between the frame and BB bearings were correct, (proper materials used, concentricity, and bearing clearances) the spindle interface becomes a non-issue. It's rocket science!
Hi! What would happen if I use grease instead of loctite to eliminate creaking? Would that work as well? Thanks!
Hi John-Great question. Grease won't work, unfortunately. The bearings need to fit tightly into the BB shell and stay put. If you use loctite, be sure to use a product that won't glue the bearings in for good. Use a product specific for bearing fit. This is a frustrating problem.
I use a spoon full of penetrating oil inside the housing. Keeps everything lubricated better than grease. Simple, you wouldnt put a motor cycle together without oil in the crankcase.
thought this was a great until i worked out that retaining compound (anaerobic adhesives) weakens carbon fibre (pva or peo glue). Swap bb30 to Hollowtech/ bb86 if you dont want the noise
i think i have a bb86 or 90. I lubbed the spindle and cleaned everything and that worked last time. This time i took out the bearings and pressed them in ok and the creak is gone. But i messed up the sleeve. It has two o-rings and i dont think i lined it up right, either when it was pressed or when i pushed the spindle in. It wouldn't go in so i rubber hammered it a little. A little too much. So i am running without this plastic sleeve. Does this just protect the spindle from water and dirt or is there some kind of pressure to keep the bearings apart?
The inside of that chainring was begging you to clean it.
Very clear, concise, to the point. You are a very good communicator and knowledgeable of the trade, however from the engineering side, the designers and companies that allowed that bad joke called bb30 press fit in carbon, should be hang by their bb's
What is difference between loctite 641 and 242 ?
Great question. Loctite 242 is a straight-up threadlocker. Loctite 641 is a retaining compound specifically for cylindrical bonding (i.e., bearing fit). It is medium-strength, meaning it's good for parts where disassembly might be required periodically for service.
Double Arrow Metabolism thank you..
399 ???
Not c clips but snap rings
My dh bike got pf30 bb30 but this seems to help me
Looks like most of the big companies are switching back to threaded BB. Specialized dumped it this year on their FS Bikes and using threaded BB. Press fit was a joke on the lower end bikes.
Imagine Brunel designing a BB30. Wouldn't happen.
According to Henkel, retaining compound should be applied to both surfaces being mated together, not just one.
I've done the very same thing you've shown here just this past weekend and I'm already hearing creaking. Damn cannondale; go back to English Threaded!
Man, that's so frustrating. Sorry to hear it. I share your BB30 frustrations. I've discovered with some trial and error that cleaning the outside of the bearings and the inside of the BB shell with an aerosol degreaser results in a better bond and makes the solution last longer.
I've done so many different things lol Loctite, 100% cleaning, factory retaining clips, etc.
Buy properly designed frames! Press fit MUST be machined. Stay with threaded shells. Everything else is marketing drivel. Otherwise, tolerate your incessantly creaking BBs to enjoy a questionably stiffer crank! Even if it stops creaking it will come back and bearings will wear out quicker. But go ahead and splurge on those $100 bearings!! The bike industry loves your ignorance!!
Shirley HSW haha!! Just use Holy water! Maybe that will help!!
If you have a creek on your BB30 bike, look for Hambini here on RUclips. He’s an engineer that makes one piece bottom brackets for all bb30 systems and they’re manufactured to aerospace engineering tolerances. They make every and all creaks go away.
Wrong press = you damaged your bearings.
You had to push the outer and inner rings at the same time to prevent damage to the inner surface. If you only push from the inner ring, the power you put on is transferred to the outer through the balls. This creates too much pressure on the contact of balls and races and causes eventually damaged points inside the race. Your bearing will then not run on a smooth surface and take more damage in every turn. This will lower your bearings lifetime and cost you watts.
The Shimano V2 Octalink BB of the late 90's & 2000's were superior quality and simple to install, why have BB's become so much more complex since.
I worked at FSA for two and a half years. While there myself and a coworker experimented with different compounds to see what lasted the longest in preventing the creaking from coming back. We found that Locktite 480 worked excellent and lasted longer. It has a holding capacity almost identical to 242 but has components in it that make it feel like rubber when dry and it actually expands. So it does not break free as soon as the 242. Also when used with a press fit plastic cup in a carbon frame it expands and forms into a rubbery material to fill voids between the bearing case and frame as carbon layups are not perfect. It does not hold so great as to be a detriment when trying to remove a worn out bearing.
Hambini says no
Why not add locktite to the spindle instead of grease, the inner race should be "slipping" from the axle. Nice video
You want to eliminate that annoying creak get yourself some earbuds and listen to some good House music. You won't hear the creaking and the beat will help your cadence and motivate you to ride harder. It worked for me.
Funny, but I would never impair my hearing or distract my attention from traffic or other threats.
@@skcyclist Why not? Everybody using the roads drives distracted. I see people in group rides texting even. It's all a game of chance the way I see it. You truly want to be safe stick to the trails and off the roads. No matter if you're wearing earbuds or not, you are not safe on the roads.
@@charlesmansplaining it's not safe, that's true, but I want all my faculties tuned in to potential threats. You and others are welcome to do as they please.
You don't wanna crank on this???
Square taper JIS 4 lyfe! You are doing it wrong with the extractor. The hex goes finger tight then back it out a little. The handle does the pulling.
I would never press a bearing in by the inner ring. I would think you're going to damage the new bearing. Sure bang out the old bearing from the inner ring...but I would only press the new bearing in from the outer ring. If I saw a shop do what you just did...I would walk out of there and never go back.
Oh yeah 😎. OR? Rent a "Blind Bearing Puller", from AutoZone. Used to remove the pilot Bearings or pilot Bushings from the Flywheel that transmission shaft Rests/rotates on allowing Flywheel and transmission to turn together. Insert one hook 🪝and hook the inside of Bearing/Bushing 🪝with the Bearing Puller and Jerk the slide Hammer 🔨 away from Bearing and pop that puppy 🐶 right out.😄
The best solution is to not buy Cannondale, their manufacturing tolerances are crap. Go for look, Giant, Time or BMC
I'm afraid you're wrong. The creaking is caused by the bb axle fretting inside the inner race, not by the bearings moving in the frame. Look for blueing of the grease on the axle as evidence as well as signs of wear where the axle sits inside the races. Simply refit the axle with a smear of bearing fit compound to cure the creak.
6:36 what is it?
Park Tool polylube.
Only i understood from the vid is that i need to go my lbs.
Nice explanations of how to properly use the crank puller. As well as the rest of the video.
Your pressing on the inner race wrong too.

JUNK !!!! you need to press the outer race of the bearing !! You have DESTROYED that bearing
The crank shaft fits way too lose.
Find bearings that will press fit both the shell and shaft!!!! Hey!!! You didnt solve the problem...!
Nooooooooooo. You pressed in that bearing by pushing on the INNER race. That is definitely not how you do it. Gotta push on the outer race
engi fails!
WTF!!!! Pressing on the inside of the bearing??? That's why Press fit are a joke, people dont know how to handle it... And Bike manufacturer cant keep the tight tolerance, that is needed for a correct fit.
Mijn God, wat een amateur!
Misalignment issue on canondales major issue engineering wise a 5 year old could do better. Total missing point off the problem ignoring this instead get a real understanding of what going on and real emotion at hanbini . Com
The old systems are better.
you do it wrong
cannondale makes a bb30 to bsa conversion tube.
Press this in with strong locktite and enjoy your creakfree bsa frame.
btw bsa fits any crank yes even bb30 ones
Ianis Caratti most bb30 cranks won’t fit in a bsa bottom bracket as the spindle is not long enough.
