Every watt saved moves you closer to the podium. Standard drivetrains harbor hidden friction that drains your energy cadence after cadence, lap after lap. Replacing stock components with precision engineering reclaims that lost power, transforming your rear derailleur into a high-efficiency instrument of speed.
Engineered in Barcelona, this component integrates a forged carbon structure with a 7075-T6 aluminum tooth core to deliver instantaneous shifting response. The fiber is continuously molded around the metal, eliminating the standard flex found in plastic pulleys and maximizing mechanical power transfer. As you accelerate, the ultra-low friction hybrid ceramic bearings deliver a whisper-quiet, frictionless rotation that redefines high-performance pedaling.
