Raceface BB's – Are they all Sh1te?
Thought i’d give the SS a once over before the FOD ride on Sunday and the BB was pretty much seized solid. It’s eventually loosened up but feels a tad rough to say the least.
This BB was fitted in Spring and has done a mighty 260 miles. They last BB i had that went tits up quickly was also a Raceface (900 dry miles on the FS).
Why can’t Raceface get a BB correct? I seem to recall that there is now a guarantee on their BB’s but why would i want to bother given that it’ll just give up the ghost again in a few months? My XT ones seem to last much longer and they’re not exactly expensive.
Can you peel off the seals on Raceface and regrease them like you can on some of the XT ones? Chainset/BB is a Ride SS if that helps at all.
I think this will have been my last ever Raceface transmission component purchase….
Oh, and the bike has been hosed down to clean it but never with a pressure hose. So much for the simplicity of SS!Posted 7 years agoTandemJeremyMember
I stripped and regreased a raceface bb. It was full complement type bearing and the bike had been built with too much preload on teh bb ( from new) which caused the bearings to push out of the race as it was side loaded and that caused it to lock,
Its certainly worth attempting to strip and regrease.Posted 7 years agoTrimixMember
I too had a similar problem – after much research I read a very good artical that explained the likely problem.
There are very tight tollerances between the bearing balls in them, a factor when they use lots of bearings. What happens is the dirt that gets in has no where to go and grinds the balls.
With bearings that have fewer balls the gaps are bigger and the dirt gets pushed away from the surfaces so wear slower.
I destroyed my one in three weeks and sent it back to Wiggle, who replaced it with a Shimano one – which lasted well over a year. (including winter mud riding)Posted 7 years agotthewSubscriber
Yeah, pretty rubbish here too. I’d be interested to know, really how much difference does facing the shell make? I had similar issues with Truvative ones on my old bike, changed to Shimano and that lasted at least 18 months, but had it faced at the same time. Would be interested to know which change had the most effect.Posted 7 years agoj-clawMember
Older external RF BBs weren’t very good… You’ll probably have issues if you have one with black or gold cups.Posted 7 years ago
The newer ones are much better though… The silver Team XC BBs have a retainer bearing which is essentially the same as a Shimano bearing, so you should get a similar lifespan.
The new Turbine BB has the same retainer bearing, but the cups have been machined right down to save weight. A Turbine BB weighs 85g, compared to 113g for a Hope & is pretty much half the price. They’re also fully serviceable & replacement bearing/seal kits are readily available.
