    Is my BB unusable?

    Apparently I bought a crankset that has a 70mm bottom bracket with it, and I need 68mm. I guess I am going to have to find a new bottom bracket, huh?

    If you have a 68mm BB, then yes.
    Is this a square taper?

    The real problem may be threading, not width. Most 68 mm bottom brackets are English threaded and most 70 mm bottom brackets are Italian threaded. The two thread types are completely incompatible
