ABSTRACT:
A bicycle crank arm has an internal flange with a plurality of mounting holes for receiving mounting fasteners. The internal flange allows the crank arm to be wider, which lends it to being cast out of a light alloy, such as magnesium or aluminum, producing a stronger and more rigid crank arm of reduced weight. Also, the mounting fasteners and the internal flange are hidden from sight, enhancing the appearance of the crank arm.
