The completely redesigned tooth profile, based on the principles of the Ultra-Drive project, allows for extremely fast shifting response. The synchronization achieved through the development of a specific positioning of the teeth on each sprocket enables a smooth and quick transition from one gear to another. To maintain rigidity, the last two sprockets are mounted on an aluminum frame.

Sprocket synchronization: special phase positioning of the sprockets for a fast and precise shifting process results in lower chain stress.

Teeth with Ultra-Drive design: optimized downshifting under load.

Nickel-chromium surface treatment: reduces friction between the sprocket and chain and increases the durability of the sprockets.
