I bough a Cannondale Capo second hand, and it came with an ISIS bottom bracket installed and FSA Carbon Pro cranks. The crank arms are carbon and the spider is some kind of metal.
The spider has unfortunately worked a bit loose (apparently a known problem), so I'm looking to replace them with FSA Carbon Track cranks (where the spider and crank arm are all one unit)
Do I need to worry about throwing the chain line out? And should I be taking this opportunity to move from ISIS to some other BB standard?
