• Shit, fair point. I didn't build it and I'm not sure I can take the BB off to check.

    Cranks should come off with allen key, BB might be GXP - does that use BB9 tool?

  • BB might be GXP

    FSA should be MegaExo, which is near enough identical to Shimano HT2 to work on apart from some cranks being self-extracting rather than having pinch bolts. There is a wave washer for bearing preload on the self extracting variants, and they vary between having the axle permanently attached to the NDS or DS crank, so on this occasion you might actually have to RTFM 🙂
