Yes I think mentioned they’re both square tapered the Bb and crank arms. You didn’t ask me if I knew what size square tapering they had. My real concern was if the bmx crank arms have a larger square tapered hole than the originals and would sit loose on the bb even when tightened down. Should I worry about that? The bmx arms I want to use are 140mm. The originals arm idk 165mm maybe I’m losing length but I feel like I’m getting the torque I lost back with a 34 tooth chainring.
