Hey, I just got a new FSA Xtreme, which come with what must be self-extracting bolts. The bolts themselves are bolted onto the crank. I'm trying to slap that baby on a Truvative BB. But for some reason it doesn't want to go on.

Anybody have any insight to this situation?

Cheers.

I think there may be some ISIS cranks taking 14mm bolts and some taking 15mm. Not too sure, but might be worth a look.

From what I remember TruVativ BBs use 14mm bolts and the FSA cranks come with 15mm bolts (same size for Shimano XTR BBs). When I got my FSA carbon cranks and wanted to use a TruVativ bb so I could ride my bike but I ran into the same problem with the different size bolts. I finally ordered a FSA ti bb and those came with 14mm bolts for the cranks.
