Gear switch for bicycle ratchet

摘要

The ratchet gear switch has a ratchet spring (6) to engage the ratchet (5) of the rotating unit (4) at the laying point of a ratchet unit (7). The ratchet unit rotates in a pan (8) of the ratchet spring, and is tensioned against the ratchets. The ratchet element is made from plastic to decrease the gear change noise.
