ABSTRACT:
A multi-state bicycle chain gear assembly includes a chain gear which has a gear body having a plurality of teeth and at least one partial gear also having a plurality of teeth. The partial gear is connected to the gear body such that it is shiftable axially relative to the multi-stage chain gear assembly. The partial gear and the gear body form a complete chain gear wherein each tooth is positioned within a single plane. The partial gear is connected to the gear body such that when the partial gear and the gear body are driven to rotate as a complete chain gear, the partial gear is shifted less at its front side defined relative to the drive rotation direction of the complete chain gear than at the rear side of the partial gear defined relative to this same rotation direction.
