Background: I was getting a light clunking noise and vibration from my Campy Centaur bottom bracket. After tightening everything up in the area, the bb seemed to be the culprit by the process of elimination. So I bought a new Centaur black bb.
The current problem: I installed the new Centaur bb, using the torque wrench to make sure that everything was tightened properly. I went out on a test ride, aaaaaaaaaaannnnnnnnnnnndddddd it's still clunking with the new bb.
BTW, this clunking is intermittent--no real pattern, but happens most of the time. It's most apparent when I'm going up hill or riding out of the saddle. There is no clunking when the bike is on the rack and I am pedaling it with my hand.
Does anyone know what the problem is and how to fix it?
PS: I do have successful experience changing bottom brackets, but only with Shimano Ultegra.
