Abstract
A crank assembly formed as a unitary composite structure, the crank arms and crank shaft being hollow to provide maximum weight reduction, the crank arms being over-sized to provide the necessary stiffness and strength. The unitary composite crank assembly may further include a crank claw integrally formed with the crank assembly. Additionally, a spider may be integrally formed with the crank assembly reducing the amount of parts for the assembly, increasing stiffness and reducing overall weight.
