CeramicSpeed OSPW RS ALPHA derailleur cage for Shimano GRX/XTR/XT 12S Di2, Silver
CeramicSpeed OSPW ALPHA for Shimano GRX/XTR/XT 12S Di2 is a top-tier oversize pulley wheel system designed specifically for gravel, cyclocross, and mountain biking with Shimano GRX, XTR, and XT 12-speed Di2 electronic derailleurs. It combines extreme efficiency, durability, and bearing protection in demanding off-road conditions.
The system utilizes 14-tooth and 20-tooth ALPHA Disc pulleys with a composite tooth material for longer lifespan and reduced chain noise, while the full aluminum discs minimize the risk of catching stones or mud. Inside the ALPHA Disc pulleys is the patented Active Debris Remover (ADR) technology – a combination of a stainless steel dust cover and a grooved structure that expels debris away from the bearing as it rotates. Combined with hand-built hybrid ceramic bearings, this creates an exceptionally efficient and reliable solution for riders who want maximum performance from every pedal stroke.
