    How to Make a SRAM GXP Crankset Work on a Press Fit BB Shell?

    I just got a full suspension frame from China that was supposed to have a BSA BB shell, but it has a press fit shell instead. I already have a SRAM GXP crankset and a GXP threaded BSA BB, so wondering what my best options are. This is for my 75# daughter, so not a lot of torque but she rides a lot.

    Should I get a TruVativ PressFit 30 to BSA adapter?

    Or can I get a BB that will work with my frame and GXP crankset (73mm shell width, anything else needed to determine this?)?

    Thanks - BS

    what exact pressfit shell does the frame use? What are the dimensions?

    pressfit GXP is for BB92 frames (41mm ID, 92mm wide).

    If the frame's bb actually is PF30, then you have options, but probably not any nearly as cheap as the two standard GXP bb options.

    There's a BB like this if it actually is a PF30 bb shell (46mm ID):

    Some specific fitments are odd, and you'll only find more expensive bb's for them.

    Harold, thanks for the quick reply.

    BB shell is 73mm wide by 46mm ID.

    And your link was what I was looking at getting.
