    If I understand it correctly you can use certain FSA MegaExo cranks, which use the same axle size and bearing shell size as Shimano's HTII. The carbon 'Light' series use slimmer bearing shells (6mm as opposed to 7mm) so don't fit.

    SRAM are not directly compatible as they have a stepped axle 24mm one side 22mm the other.

    However adaptors are available or you can replace the whole BB with an alternative so you can run Campag etc.

    You can use any chainset that uses a 24mm spinfle or similar i.e. Shimano HT2, FSA MegaExo (all types), SRAM GXP, Campagnolo/Fulcrum and Race Face. You can't use BB30/PF30, BBright or BB386 i.e. 30mm spindle cranks except the Rotor ones as they have a longer spindle.
    Make mine an Italian, with Campagnolo on the side..

    Can't use GXP in that particular BB. You can get a GXP PF BB or use Hope adaptors, I think.

    You can definitely use SRAM with a SRAM BB. I have a SRAM GXP crankset installed on a Canyon frame that has BB91. I would have to remove the crank to check the BB. Best to check with SRAM if you want to be sure to get the correct BB
