Hi, I'm looking at some old 737 crank arms (to buy) and have no idea if they are JIS or ISO square taper? Also, would like to know the chainline (middle ring) with a standard 113mm BB if anyone should have such info?
Lastly, any known issues with these cranks, as they need to be durable for my riding style/abuse :shock:
Cheers
