    Hawk Bottom Bracket on Trance 29er

    Installing an XX1 on a 2013 Trance 29er
    The old shimano BB doesnt look like it will work, even with the adapter.
    I think this might work with the Hawk BB86/92 which has a lot less friction than the BB from Shimano.
    Has anyone tried this BB on this frame?

    Is it a GPX or BB30 XX1 crankset?

    GPX crankset
    SRAM service manual says to use 1-2.5mm spacer on drive side but that's for a SRAM BB
    Frame is 89.5 mm

    GXP BB92 is what you need: SRAM GXP BB92 Bottom Bracket | Backcountry.com

    I've personally not seen any Shimano BB with "a lot of friction" that was installed correctly. I'd check that the BB is faced correctly and the preload adjuster isn't set too tight.
