    This is what I have now: Custom Shimano FC-M542

    As for what I want I'm not sure whatever will be compatible with those cranks and my frame?

    I like Google A search for Bottom Bracket types.

    Complete guide to bottom brackets

    Most likely you have a "Conventional threaded' type bottom bracket.

    If you order a Sram Crankset order one for a conventional bottom bracket 68/73mm English thread.


    Sram and Shimano use different bottom brackets but they both fit in the same frames/BB, the "hole" for the crankset spindle is a different size.
    Duct tape iz like teh Force. It has a Lite side and a Dark side and it holdz the Universe together.
