Pedals to Crank arm sizing
Are there different thread pitches and shaft sizes to pedals and crank arms, or is it universal? I'm winding up with crossed/stripped threads. When I search on google for crank arms and pedals, they always come separate. My pedal fell off, the threads were all stripped inside the crank arm. I put a new crank arm on with the same pedal, and I coiuldn't get the pedal on the crank arm without crossing the threads. How do I stop this from happening?
