Replacing my Crankset and Bottom Bracket...

Below is what Fuji lists as the crankset and bottom bracket for my 2009 Fuji Roubaix RC. Is there enough information there to determine specs for replacement parts (e.g., Shimano)? (The crank arms are 175...) (It is Greek to me.)
CRANKSET
FSA Gossamer Pro MegaExo w/ Integrated spindle, 39/53T 7075 CNC AL
BOTTOM BRACKET
FSA MegaExo Exterior Bearing System

Thanks,
Wayne

If you are replacing both crankset and the bottom bracket you only need to match the number of teeth on the chainrings (53 and 39) and the crank arm length. The chainline is most likely the road double. Also, how many speeds does the drivetrain have? This is also an important factor.

Hi Wayne;

If you are looking for an exact replacement due to damage, etc, you have sufficient information.

If you are looking to make some changes (lower gearing for example), you have sufficient information to start looking, but maybe not enough to close.

If your descriptions are correct, then you have a BSA threaded bottom bracket shell.
So you can buy a Shimano or SRAM GXP crank with the appropriate BSA threaded bottom bracket. Or any other crank that comes with a BSA BB.
Most of the 30mm cranks won't work - you'd need one of the one's designed for a BSA BB.
