C-Bear Bottom Bracket Installation & Creaking
Moderator: robbosmans
I looking at buying C-Bear Campagnolo UT 386Evo Bottom Bracket for my Carbon Cipollini NK1K and would just like to ask a couple of questions before as there seems to be conflicting information of installation.
Should I use Loctite, anti-seize paste or install dry? Is there any other installation methods I need to know as the C-Bear website is'nt massively helpful!
Are they a fix for creaking or could there still be a chance as I don’t see how they are massively different to the Campagnolo UT cups? Still pressing in the same bottom bracket shell and they don’t look much wider, they do have an inner sleeve if that makes a difference.
Finally are there any other options out there? Looked at Wheels Manufacturing but they don’t seem to sell this combination.
Thanks.

C Bear recommend grease, not loctite or a dry fit.

I've had a Cbear ceramic BB in my SL4 Tarmac for probably 5 years and not a single noise from it that whole time. The stock Spesh BB cups defnitely creaked. It has been removed and cleaned once I believe, not sure how it was installed though.
Just had a creaking C-Bear BB386/GXP which was mounted with carbon paste - maybe teflon grease would have been better?
I will try the threaded Wheels MFG now, as it seems the most solid solution to me and I like the easy to replace bearings.
But that's not compatible with some powermeters...
So there's also a third option from VCRC:

But no Campy UT option I fear.

I have used c-bear t47 (obviously threaded) and have been impressed with the smoothness of the bearings and quality of the build.
However, you'll be using PF. Unless you use a threaded BB (like wheels manufacoring) or loctite (blue one, not the red one), you'll probably end up with a creaky BB.

Thanks for the advice. I’m liking the look of the BB Infinite bottom bracket, looks like I’ll have less possible creaking issues with that design compaired to C-Bear. It’s a shame Wheels MFG don’t offer a 386 Evo UT solution.

Just be aware that the bbinfinite is an issue if you have cabled shifting and need to get at the cabling or battery. Also, mine was slightly undersized, getting the UT crank in was a bit of an act as it wasn‘t slipfit post install in the frame. Creak free though.
mine was also installed with anti seize, and it's creaking every time I'm out of the saddle.
occasionally I remove the crankset and regrease the spindle, which makes it silent for couple of rides, but then it's creaking again...
I'd recommend Kogel's Aqua Proof Paste for installing or loctite: https://www.kogel.cc/collections/tools- ... tion-paste
Shut-up grease is rebranded Morgan Blue AquaProof Paste. I like it for its tenacious anti corrosive properties. But if your pressfit application is such that there is creaking (caused by movement between the surfaces) then you should really be using a retaining compound (Loctite 609, plus Primer Loctite 7649). Applying grease to a creaky fit will just mask the issue for awhile by preventing the “creak” sound as it moves, but it is actually facilitating that movement, and associated wear. The creak will return eventually. That is not what you want. You want no movement and retaining compound is appropriate in these cases.
