    Difference in SRAM GXP and BB30 Spider?

    For the SRAM cranksets that have a removable spider - S-1250, S2200, X.7, X.7, X.0, etc. - is there a difference between the GXP and BB30 models?

    I know they sell two different version, but I don't know if there is actually a difference. I would assume so.

    I would be interested to know for sure.

    I've swapped a spider between GXP and BB30 sram non-series road cranks. I believe they're interchangeable between GXP and BB30 mountin bike cranks as well. Just 3 torx bolts.

    No they are differnt on the mtb cranks. put one from each next to each other and they are clearly different offset.
    The S900 road crank does use the same spider for both, that's because it's the same crankarm for both BB30 and GXP on the S900. Not the case with the MTB stuff.

    Rammer is right. Tried to swap, but the chainline changes to much.
