Chain transmission for bicycle with rear suspension

摘要

The chain transmission is used on a bicycle that has a rear suspension and the pedal mechanism attached to the forward triangle of the frame. The transmission has a principal return pulley (14) which diverts the route of a section of the chain (11a) between the wheel pinion (12) and the chain wheel (10) for the pedals (9). The chain is diverted towards the articulation point (7) of the rear suspension.
