Each sprocket tooth is engineered to achieve the highest levels of synchronization, shifting speed, and quiet operation. A double plate system for the six largest sprockets provides very high torsional stiffness, ensuring optimal operational precision even during shifts under load. The surface treatment of the 11 steel sprockets guarantees long component life and maintains performance over time.
ULTRA-SHIFT TOOTH DESIGN
Each tooth of the sprocket pack is designed and positioned to perform a specific function such as chain ascent or descent or maximum power transmission to the wheel.
ULTRA-SHIFT SYNCHRONIZATION
The sprocket phasing allows for maximum shifting performance without hesitation: speed, precision, and quietness, even under load.
REINFORCEMENT PLATES FOR THE SECOND AND THIRD CHAINRINGS
Increased stiffness of the sprocket set - operational precision.
NICKEL-CHROME SURFACE TREATMENT
Reduces sprocket/chain friction - extends sprocket life.
