I have a Trek SSL (OCLV 55) carbon frame with Campy Chorus. However, after about 3-4 months of riding I inevitably have to replace the BB cups due to heavy corrosion.
I've been to 3 different mechanics over the past 5 years who have narrowed the problem down...
- the frame does not contain a hole on BB to drain standing water from inside, due to the external routing of cables below the BB. Instead, Trek offers a bolt with a tiny hole that secures the cables and is supposed to allow drainage. However, it typically is filled with gunk and does not drain.
- unlike other BBs, Campy external cups do not connect to one another...as such, the sealed races are exposed to any standing water/gunk that settles in the BB
- regardless my efforts to manually drain the frame, this Trek/Campy combo continues to fail. After a long sportive outside of London 2 weeks ago that, of course, included some rain, I can barely turn the cranks.
Has anyone else had a similar problem?
Am I doomed to fail with this combo from the Man behind Shimano/Trek sponsorship?
