Ceramicspeed Alpha Pulley Wheels Kit

The CeramicSpeed Alpha Pulley Wheels are high-performance bicycle drivetrain components. They feature patented Active Debris Remover (ADR) technology and solid aluminum/composite disc designs to reduce friction, block grit, and prevent mud or dirt buildup in extreme road or off-road conditions. Prices typically range from $400 to over $700 SGD depending on whether you buy stock-size standalone wheels or an oversized OSPW RS system. Key Technologies Active Debris Remover (ADR): A patent-pending dust cover and dynamic grooved seal system that actively expels dirt and debris during rotation. ALPHA Disc Design: A two-part construction pairing a narrow-wide composite tooth profile (for noise reduction and wear resistance) with a solid aluminum outer disc. Low-Friction Bearings: Signature hybrid ceramic bearings designed to minimize drag compared to standard OEM setups. Formats & Options ALPHA Pulley Wheels (Stock Size): Compact, standard-size replacement wheels that fit existing stock derailleur cages without changing the entire cage assembly. [1] OSPW RS Alpha (Oversized): Integrated oversized pulley wheel systems (typically 14/20t combinations) built into an angular, reinforced carbon-polymer cage for maximum efficiency gains. Compatibility SRAM: Fits modern Road AXS groupsets including SRAM Red (D1/E1) and Force (D1/E1). Shimano: Fits high-end road models like Dura-Ace (RD-9250) and Ultegra (RD-8150).
