Upgrade your drivetrain with precision-engineered pulleys that reduce friction and weight in the derailleur. This setup translates to smoother shifts, more efficient power transfer, and cleaner shifting under load during climbs and sprints. With less drag in the rear, you ride more confidently, regardless of terrain or weather.

Who is this for?

Riders who demand crisp, reliable shifting and maximum efficiency from every pedal stroke—especially those upgrading to an 11-speed GRX/RX setup, or seeking to improve endurance rides and long-distance performance.
