Abstract
A chain sprocket includes a disc-like base having an outer rim with teeth on an outer periphery thereof, a hub having a crank arm-accepting slot formed therein, and a plurality of spokes extending radially from the hub to the outer rim. Stiffening fins are formed integrally with at least some of the spokes. The stiffening fins extend axially from one side of the base, have a greatest axial dimension adjacent to the hub, and taper towards the outer rim to provide the sprocket with axial reinforcement.
