Thinking of changing to compact cranks. I have a 2005 Giant TCR2 Composite, which has a 2005 Ultegra 10 speed 52/39 crank/bb.
The various integrated cranksets (eg FSA) come with different BBs - I found a FSA compact crank on sale with an "Italian" BB, as well as another one with a 107mm BB.
Questions:
1. does "Italian" means Campy compatible and "English" means Shimano compatible? Is this an issue with my frame's BB shell? Will an Italian BB fit my frame?
2. do different BB sizes (eg 107mm, 108mm, ISIS) all fit all frames? Or do they have to match the BB shell in each frame? I guess they may result in different Q-factors, but such small differences aren't important to me.
Thanks for the help
