CeramicSpeed OSPW ALPHA RS ALPHA derailleur cage for Shimano GRX/XTR/XT 12S Di2, black
The CeramicSpeed OSPW ALPHA for Shimano GRX, XTR, and XT 12-speed Di2 derailleurs is a top-tier off-road system with oversized pulleys, designed for maximum efficiency and reliable protection in the demanding conditions of gravel, cyclocross, and mountain biking. It uses 14-tooth and 20-tooth ALPHA Disc pulleys with a composite tooth material for longer lifespan and quieter chain operation, while the full aluminum discs minimize the risk of snagging debris or twigs.
At the center of the ALPHA Disc pulleys is the patented Active Debris Remover (ADR) technology, which, thanks to a stainless steel dust cover and special grooves, expels debris away from the bearings as it rotates. Combined with hand-built hybrid ceramic bearings, this creates an extremely efficient and durable system. The redesigned and reinforced cage, inspired by the road OSPW RS systems, is engineered to handle the extreme demands of off-road riding without issues.
