I've had fun posting on this forum. Really! But, as many of you could probably tell, often I feel like that kid that can't swim that just wandered into the deep end of the pool. I feel that way right now. The problem: I have an Italian bike frame with an Italian BB. (Who would have guessed?) For my own sake, I wont go into all of the expensive stupid mistakes I've made if you don't mind. But, I bought an FC-7700 crank that I would like to put on it. What size, model Octalink BB would be compatable?
