I just changed the cranks on my 80's Ciocc from Campagnolo Super Record to C-record. My bottom bracket is a Campy Centaur. After putting the new C-record cranks on, I noticed a clicking sound coming from the crank area. There is no rhythm to the clicking and it only occurs during hard pedaling, but not during every rotation. Its quite sporadic. The bottom bracket is in there good and tight.
I'm most worried that the noise is the sound of a crack somewhere in the frame. I gave it a casual look, but the paint is so dark, it seems imposible to find a crack. Its steel, Columbus SL. and I weigh about 200lbs give or take a pound.
Also, there was no clicking before I put on the new crankset, and the new one uses the Campy self extracting crank bolts.
So anyhow, any ideas about what I should do to figure this out?
