Silent and simple technology, the most trouble-free drivetrain that guarantees comfort on climbs and speed on the flat. In addition, it features durability and low weight.

The specially designed sprocket shape ensures the highest levels of performance and durability. The triangular teeth have been replaced by taller, square teeth with narrow and sharp edges, which come into contact with the chain more quickly. The bevelled milling of the teeth improves drive performance at high chain cross-sections at extreme gear ratios. The X-SYNC removes debris faster, resulting in smoother operation and extended drivetrain life.
