FSA MegaExo bb problem - bearings are clicking
I already know about the notoriously bad design of FSA's MegaExo bottom bracket, but I've read that some people have had success when properly installed - to exact specs. And I've done just that, followed all the installation instructions precisely.
My problem is that I can hear the bearings clicking on the left-hand cup. The bottom bracket is brand new, which replaced a slightly used MegaExo (less than 500 miles) with the exact same problem. It's not that the left crank arm is too tight (too much load), because I can hear the clicking by simply turning the bearing faces with my fingers. My botton bracket is faced, I'm using the new o-rings, etc.
I cannot believe it's just coincidence that the exact same issue is present with both bottom brackets. Has anyone had a similar problem with the MegaExo and found a solution, or is there anyone that hasn't had any problems with the MegaExo?
Thanks for your help and suggestions.
