CONTI-WAVE machining reduces chain noise as it minimizes the contact surface against the chain.
As your chain enters the rear derailleur at various angles, the Conti-Wave tooth profile designed for the lower pulley ensures smooth pulley-and-chain engagement regardless of gear position. The continuous chamfer form on the tooth edges reduces the contact area between the teeth and chain inner plates by 82.5%, and increases the efficiency even further while guiding the chain perfectly.
