bb30 conversion options
It’s going I’m an Alu frame. I assumed I could just take it out if it’s rubbish but does it need bonded in?
If I need to bond it and it’s not going to squeak relentlessly then not an issue as I don’t envisage ever not using a shimano crank, but if there’s a risk it’ll be a liability I’ll stick with a praxis which I have on my carbon full suss, and which works perfectlyPosted 4 months agorapidrob95Member
I have a 2011 caadx, and I fitted a rotor bb30 to 24mm adaptor after having the usual problems. IIRC you do need to watch out for obstructions, I think my cable guide stuck though into the bb area. Mine has been quiet for 2000 miles/18 months, but I have started hearing a creak when pushing hard, although I haven’t investigated it yet. I threadlocked the main thread which screws the two halves together.Posted 4 months ago
No cables running through my BB, but no idea if there is anything else in there that will cause issues.
Chakaping how easy is it to fit, assuming you are running a shimano crank? Is it just a case of removing the old one and pressing in the adaptor, then screwing in the shimano BB cups? Or is locktite/glue required?
Not that I have the tools to do it myself anyway however …Posted 4 months agojohnw1984Subscriber
Tempted by this FSA thing. Anyone know if it’ll fit in a carbon Stumpy? Having got fed up with the Sram PF30 BB, I fitted a Wheels MFG BB (the one where it presses in and screws in).
One side has seized in less than 6 months and they aren’t cheap 🙁
So now I’m thinking of the faff knocking the bearing out and pressing another one in. Or, get one of these and enjoy £20 Shimano BBs that last more than 6 months. I think I even have some spare Raceface cranks too!Posted 4 months agotillydogSubscriber
The FSA ones do need to be bonded in (IMHO). I fitted one to my Diverge DSW about 600 miles ago. Too early to comment on longevity, but it feels rock solid, and I can’t believe it will be a problem.
Easy enough to press in if you’re used to doing bearings, etc. (Just be sure that you’ve got the correct ‘hand’ of thread on the correct side – from memory, the drive side has a groove around it, but DON’T trust my memory!)
I didn’t get any glue with mine (it was VERY cheap: Ribble were selling them for just over a fiver), so worth checking if you do buy one. I had something suitable to hand, but I would use the suggested epoxy adhesive if you think you may ever need to remove it.Posted 4 months ago
