The chain and sprocket must harmonize perfectly: That's why we have optimized the profile of the cassette teeth.

The result is perfect synchronization in traction and quick shifting thanks to the Ultra-Drive design.

Ultra-Drive tooth construction: enables reactive, fast, and precise shifting.

Sprocket synchronization: Sprocket configuration that ensures quick and precise shifts - reducing the load on the chain.

Zinc-plated surface treatment: reduces friction between the sprocket and chain - increasing the lifespan of the sprockets.
