FSA GOSSAMER ROAD CRANKSET with BB7800? Can FSA GOSSAMER ROAD CRANKSET be used together with BB7800 Dura Ace from Shimano?
No. Although they appear to fit together, they're slightly different. I made this mistake once (except the other way round - shimano chainset in FSA BB) and knackered the BB very quickly. FSA BBs are pretty cheap and easy to get hold of though.
