Conti-Wave

Conti-Wave machining reduces chain noise by minimizing the contact surface with the chain. The chain enters the rear derailleur at different angles. A Conti-Wave tooth profile developed for the lower derailleur pulley ensures smooth engagement between the derailleur pulley and chain, regardless of the gear position. The continuous beveling on the tooth edges reduces the contact area between the teeth and the inside of the chain by 82.5%, further increasing efficiency while guiding the chain perfectly.
