I bought a Centaur UT crankset in December and after putting it on my bike, I used it on the trainer throughtout the winter. From the middle of March, I started using it outside....no rain, a bit of riding through a couple of melted snow puddles but nothing that seriously contaminated the bearings.
Starting about a week ago, I start hearing and feeling a clunk clunk when I put out a little torque.
I took it apart the other day and....the clip that holds the bearings in their cartridge is completely in smithereens there are pieces of it floating in the cartridge, with the bearings now not evenly spaced, but rolling *****-nilly.
Fortunately, I had an extra set of Campy cranks on my TT bike that I took off and stuck on the road bike for now.
Any ideas as to what happened?? I'd like to not have it happen again
When I assembled them, I followed Campy's instructions and put in a good amount of grease (Phil Wood). The bb shell (it's on a CAAD 9) seems to be within spec (68 mm). Admittedly, I am not sure whether it has ever been faced.
Also: does anybody know of any sources for Campy UT bearing pullers? When the bearings go south on a UT crank, is there no other option but to send it back to a Campy service center?
