CeramicSpeed OSPW RS Alpha for SRAM Force E1, Rival E1 The CeramicSpeed OSPW RS Alpha Northern Lights edition is a premium performance upgrade meticulously engineered for SRAM Force E1 and Rival E1 drivetrains. This system introduces a modern, angular cage design that complements the sleek aesthetics of contemporary road and all-road bikes while providing a substantial reduction in drivetrain drag. The limited edition Northern Lights finish features a radiant, iridescent surface inspired by the Nordic aurora, offering a striking visual statement. By combining oversized pulley wheels with hand-built hybrid ceramic bearings, this system ensures that every pedal stroke is more efficient, helping you maintain speed and conserve energy during demanding rides. Advanced Debris Protection To ensure peak performance regardless of road conditions, this system utilizes the innovative Active Debris Remover technology. This patent-pending feature employs a unique dust cover anchored within the pulley wheel groove, creating a sealed environment that makes it virtually impossible for grit or mud to reach the bearings. This is further enhanced by a bladed groove structure that dynamically extracts contaminants as the pulley rotates. Tested in the rigorous environment of professional cyclocross, the ADR system guarantees that your ceramic bearings remain smooth and protected, providing consistent efficiency even when the weather turns. Durability and Precision Engineering The OSPW RS Alpha is built around the robust Alpha Disc pulley wheels, which feature a two-piece construction for maximum longevity. A solid aluminium disc eliminates the risk of road debris getting caught in the pulley spokes, while the composite narrow-wide teeth provide exceptional wear protection and a significantly quieter ride. The entire system is housed in a reinforced cage that has been redesigned for superior strength and stiffness, ensuring crisp and reliable shifting under load. This combination of reinforced carbon fibre and high-tech composites offers the perfect balance of minimal weight and the extreme durability required for high-performance cycling.
