After a couple of bottom bracket repair attempts, I developed a simple three step process for dealing with BBs across all of my bikes: 1. Take to bike shop 2. Take out wallet when done 3. Take bike home to ride I have found that it was quicker and cheaper than any other approach I've tried.

Si first says that you should "go in dry" and then makes weird noises while "going in". That's the kind of humor I'm talking about!

@Rob For road bike? Sure your bike is set proberly? Not too long chain?

Thanks GCN! I've always been too scared to do anything to a press fit BB, but this didn't look that painful!

That bearing press is $150-170, while the cheaper version (HHP-3) is the same as homemade ones using a bar of threaded rod and press cups you can buy for a couple bucks. As someone who has done the press and remove, a number of times, the expensive press is a 1000x better, than the cheap one, but pricey enough to make taking your bike to your local shop a value proposition.

Best vid about the subjekt so far, excellent!

very helpful - that park tool bb30.3 is a super tool...after years of hammer & stake removal I purchased one and what a easy tool to use and no damage to frame or BB...the bearing caps can be put onto a simple bolt and double nut setup and used as cheap but effective press :)

I've found this video super useful. Thanks a lot it cleared out plenty of questions!

My how times have changed. Many of the early press fit Bb adopters have turned back to threaded. Thanks for the video, I DO have one bike that has a press fit, this was helpful!

Excellent video just 8 months later than I needed it.

Well done Si. Really good video !

Thank you for your outstanding video. You answered all of my questions :)

Great job Si. Thanks so much.

Really good descriptive video. Thank you :)

Wheels manufacturing has a thread together bottom bracket for BB86. Their instructions say to never to press in the bottom bracket dry but rather to use Teflon grease on a carbon frame. By the way, this is a very nice BB and usually solves any creaking problem!

Been running a praxis works conversion bb to allow for shimano cranks on my specialized amd have been extremely happy with it.

Most definitely. Before you even assemble the bike or have someone else assemble the bike for you, check Praxis BB out first for a preemptive solution to terrible BB.

I recently purchased a BMC SLR01. It came stock with Ultegra. After a few rides, the chain was making a lot of noise as it went through the front derailleur. I had a professional mechanic who set up the front derailleur correctly. My pedaling felt very sluggish, and wore me down after a mere 12 mile or riding it. A far as I can tell, it comes with press in cups, like the ones you showed where you use the tool to press them in. I took it back to the shop where I got it, and they said the crank needed to come off. I heard them whacking away at the bottom bracket - which leads me to believe they removed them and put them back in. You specifically stated after removing them, they are not really made to re-use. I think they out them back i after removing. Now the pedaling feels even MORE sluggish, and the chain is making even more noise as it goes round the crank and through the front derailleur. :(

Another great video guys !

Just replaced my BB press fit with home made tools and worked with out fault and saved me £££££.

not only is Si always a candidate for WattageBazooka but also a damn good bike mechanic!!

Great help! Thanks!

Great video Si! Consider the Enduro BBT-003 BB tool for BB86 for removal as you don't have to use a hammer to hit the cup out (ouch!). You might scuff up the inside of the bracket (although cosmetic) or likely jack something up as you inevitably will not hold the frame steady while you pound away. Just my $.02 worth.

Impressive workshop.

This video was my most waited one. Even if it is an easy task I love making sure I aint f**ing it up.

another great mec video, cheers

How to establish you have a press fit bottom bracket: Pedal your bike lightly up and down the road, if you hear a horrible squeak/creak that would almost 'push you over the edge' should this sound have to be endured for anything longer than about 2 seconds, you know you definitely have a press fit bottom bracket

All it means is that you have a PF BB... some squeak more than other but they all do (or eventually do). You can always temporarily fix the problem but the cost of replacing BB's every time they squeak plus the work time to replace them soon adds up. If you want a permanent (or more lasting solution) get a converter to external cups and use a BSA compatible crankset.... there is a reason the highest end of shimano still uses BSA cranks they work, they last a lot longer without causing problems, they are much much easier to service and the spindle diameter doesnt really compromise stiffness the way the market wants you to think (In fact all pinarello bikes have threaded BB shells and it doesnt seem to be slowing anyone on team sky down)

Bought the tools and bearings online (Good luck finding them in a normal shop these days...) and did it myself. All in all cheaper than what the local shop wanted...

Those tools are worth more than my whole bike, let alone just the frame. ;)

Hi, I do not recomend frames with PF System. My cannondale Super six Evo with BB30 is creaking. Recentry i removed the BB30 and replaced it by an Rotor adapter with shimano crank and it is working perfectly !

Who else was anticipating that awesome sound at 2:21? and possibly got a 1/4 chub.

I have a bb90 bottom bracket and my bike shop sold me the BBT90 punch to remove the bearings (along with a bearing press). Should I be using the other tool you mentioned for the bb30 bearing removal? Thanks. Really enjoy your maintenance videos

If there is a better cycling channel on the Internet, I haven't found it yet. Si always makes a visit here informative, interesting, and usually a bonus laugh in there somewhere. As to my question, do I risk damaging my semi-expensive frame (even once in a lifetime), or do I just pay my LBS to change the BB for me as needed? How expensive can paying a pro to do it be compared to buying the tools to do it myself and maybe making a costly mistake?

My 1990 Gazelle bicycle has a press fit bottom bracket, as does my early 2000S Batavus. So definitely older than 2010!!!

What bearing press tool did you use? Was it a park one and if so, which model?

I'm watching this video in some amazement. Greasing BB30 bearings before pushing them in? That's ridiculous and a recipe for creak. Activator and Retaining compound is a must.

What a joke! In the machinery repair world we use cylindrical ( green loctite)retaining compound or epoxy, JB Weld to repair loose worn out bearings! Its merely to save money instead of replacing the damaged part to effect a proper repair. Its just a bandaid! THIS on a bike thats costs how much??? Dont drink the koolaid!! Do a little research on bearing fit and tolerances!Buy bikes with threaded BBs. You can thank me in a couple years.

PF BB hack! RJ the Bike Guy built one out of a threaded hex bolt, four machine washers, a hex nut and two wrenches. Total cost abt $10 - not counting the cost of the wrenches - which y'all should have anyway! if you are worried about scratching your frame, add in two felt pads or rubber machine gaskets - one at either end facing your bearings and add another buck or so to the total build cost.

Thats advise on how to recon PF BB vs Threaded cups is a bit too simple and one has to be more careful than that. Some bike with PF shells will come with adapters or converters to fit shimano or house-brand cranksets (Fuji does this a lot). Some of those converters have the engagements for the tool to thread and unthread the cups yet they cannot be threaded and if tried you will likely ruin your BB or your frame :( (praxis conversion BB's are an example of those)

It's probably a good idea to use stainless bearings where possible, carbon (especially raw carbon exposed in bearing cups) is conductive and there is the possibility of galvanic corrosion.

It's incredibly easy to install PF BB, i've done it on 2 bikes in a few minutes. One was a sleeve going into another sleeve, and the other was PF, but with a screw interace in the middle of the BB. Used that big turny tool in both instances, for the threaded one, i pressed one side, screwed in the other with a dedicated tool. Either way, super easy. I dont have the tool to take them out though :(

What colour type is that canyon? looks amazing :D

What did you clean it out with before installing the new one?

I've seen pro mechanics use waterproof paste (morgan blue) before fitting bb86's, it was even recommended by a bb ceramic manufacturer

Wonderful

It seems like a threaded rod and washers might do well as a bottom bracket press. I agree with not knocking them in with a wood block and hammer.

Like to know how ro remove the pressfit shells which receive the bearings. Especially the case of pressfit shells mounted on a carbon frame bracket with no alumnium sheath ....and for which the shells have been mounted appropriately with no grease.

Question: can you replace a press fit Shimano bracket with a hollow tech?

It seems I recall in another video where he recommends using grease to press in BB bearings on carbon frames. Does anyone else recall the same?

I'm getting rid of my BB30 tomorrow by fitting a Praxis Works converter, swapping the FSA Gossamer for a 105 chainset. Well....... when I say I'm, I really mean my local bike shop!

Andy7846 the praxis converter works fantistic! I have one on my and love it. Praxis has some great videos on installing it and removing it. One thing to note when removing it you cannot use the Park Tool BB removal tool it is too small. You need the Headset removal tool to punch out the pressfit side.

Nice vid and subject, thanks guys! Thumbs up for the grease& loctite mention!!

May be a stupid question as it’s not mentioned but do you need to re-face a carbon frame before fitting a new bottom bracket?

i honestly couldn't pay attention. i was staring/drooling at the bike the whole time

What locking compounds would you recommend as I am looking to replace my FSA PF30 press-fit BB into a metal frame or will grease do as well?

If you are working on a BB 30 the Enduro tools are much nicer and less likely to bodge the job. (No Hammer) Also for BB 30 grease isn't always the right answer. Incredibly scrupulous cleaning and a wee bit of loctite 7649 ten minutes of drying time and then a wee bit of Loctite 609 before you press in the bearings will usually result in a silent smooth job. Clean all surfaces before hand like you mean to not even leave microscopic dust behind.

The maintenance of bottom bracket I understand. Can someone explain why we need to change a Bottom Bracket please ?

Hello Si, good video. I like them. When removing the old bearing there are rests of a white mass inside. Is this grease or something else? You mounted the the new bearing dry. Can you explain?

Obrigado amigo

How do you know if the inner plastic tube is lined up correctly when you are effectively blind on both sides using the press???

My PF bottom bracket is glued in to stay in place. So you need to heat it carefully up before you can remove dsit. Might also be relevant for otherrs.

You guys should interview Chris "BB30" Dodman ;)

Question for GCN tech. I have a BB30 but I can take out the bearing with my fingers (and also putting it back). Is that normal? Is there something like a pressetting (similar as a torqsetting)?

Cool bike

why would someone want to remove and replace the PF on a self chewing Canyon Aeroroad? I added a Hambini PF on my 8 yr old nondescripti Columbus monocoque, as the nylon PFs only lasted about 5-10k creak free. Hambinis is magic. Good video..

I only have one question. I know that you said no grease for cabon frames, but what about carbon paste? Is that acceptable when installing the PF BB?

@lucianonarno1408

7 жыл бұрын

Harold Duran not at all, carbon paste should never be near bearings. Also it could damage the cups as it's an abrasive.

In the video when you were knocking out the old bearings it had grease in side. Then installing you recommended not to add grease. Someone installed previously incorrect?

I feel like tapping it out could cause damage opposed to pressing it out. I also feel like it would be good to use at least some type of light oil that is carbon safe to prevent chaffing. Not sure if that is the right term but that is what I am going to call it. Maybe its galling?

5:32 "we're goin' in dry" naughty stuff... :) not to mention sound effects at 5:38 and background music... :) is that a new bb tool by parktool by the way? smaller version of the previous one which is for both bb and headset press. looks like a cheaper better solution.

Hi! Is it a similar procedure for removing and replacing the slightly unusual Canyon headset bearing races? I have a replacement lower bearing race ready to install onto my Ultimate CF SL, but I don't have a bearing press (or any of the other smorgasbord of Park Tool items used in this vid). It's a much tighter fit in the head tube due to the lack of a star nut for preload. Any help (or even a vid) would be welcome! Love and hugs, Ben

I have a Giant Contend SL 1 Disc 2018, which is an entry-level bike. It comes with a press fit bottom bracket. How did that happen, do I have a high-end component on my entry-level bike?

Can you install them without the sleeve?

I have what I think is a BB86 bottom bracket. 41mm Cups with bearings having internal diameter of 24mm for 24mm Shimano cranks. Park Tool suggests the BBT90.3. This tool only hit the bearings out of the cups. it doesn't spread wide enough to be able to strike the cups out. Is this normal? Do I need a different tool to remove the cups? The internal hole of the cup is approx 28mm.

stick with threaded a single £5 tool for installation and removal, against around £200 worth of tools which'll rarely be used.
