Anyone else have a similar experience???
I built my bike up with Campy Record. First Campy bike in 14
years. Longtime Shimano user.
I noticed a "clunk" which seemed to come from the BB area.
It was worse with a pedal stroke on the drive side and got
progressively worse over time. Also was worse with out of
the saddle pedaling.
Checked everything else before taking out the BB. I checked
the pedals, crankarm bolts, rear cassette,
chain...everything.
When I did take apart the BB, I noticed an great amount of
play with the bearings in the carbon sleeve. This occurred
even when the cups were seated tightly against the bearings.
When I removed the cups, the drive side bearings seemed to
be only loosely connected to the axle and came apart very
easily. I don't know if this is normal. I would love to hear
any comments. I do know that I have a Chorus BB on my TT
bike with ZERO problems.
I have a feeling that this is analogous to the Shimano
splined BB. I always thought DA was a bit under-built and
always used Ultegra BB's.
THanks, Dave
