ABSTRACT:
A bicycle pedal crank is formed by three separate interassembled elements, namely a crank arm and two end-pieces. The crank arm consists of an element of composite material formed by overmolding of a synthetic resin on a tubular core of reinforcement fibers such as carbon fibers or aramide fibers. The end-pieces are manufactured separately and form respectively the crank hub and an end-piece for receiving the corresponding pedal spindle. The two end-pieces each have a tenon which is forcibly engaged and fixed within the corresponding end of the tubular element which forms the crank arm.
