CeramicSpeed OSPW TEAM derailleur cage for Shimano GRX/XTR/XT 12S Di2
The CeramicSpeed OSPW TEAM cage for Shimano GRX/XTR/XT 12S Di2 is a replacement cage for the offroad-specific OSPW ALPHA system, designed for Shimano GRX 717, XTR M9250, and XT M8250 derailleurs with Di2 electronic shifting. It is based on the road OSPW RS systems but is reinforced to reliably handle the demanding conditions of gravel, cyclocross, and mountain biking.
Included are large 14-tooth and 20-tooth ALPHA Disc pulleys with composite teeth for longer lifespan and reduced noise, while the full aluminum discs minimize the risk of snagging debris or twigs. The pulleys feature integrated patented Active Debris Remover (ADR) bearing protection, which uses a stainless steel shroud and a grooved structure to push debris away from the bearing area as it rotates. Combined with hand-built hybrid ceramic bearings, this ensures maximum efficiency and drivetrain protection.
