After reading your experince, I am confused as to whether it's the bottom bracket or the crank that has the issues?? Perhaps both?? At any rate, as a shop owner, and someone that has used Campy for the past 15 years, I would think that either might be easy to find. Hopefully your LBS will find what you need, but if not, let me know... I'm sure that I can come up with something... same as many others here ...

Good luck!!
