CeramicSpeed OSPW ALPHA TEAM - RS ALPHA TEAM Logo derailleur cage for Shimano GRX/XTR/XT 12S Di2, black
The CeramicSpeed OSPW ALPHA for Shimano GRX, XTR, and XT 12S Di2 derailleurs is a top-tier oversized pulley wheel system designed for maximum efficiency and reliability in demanding conditions. It uses 14-tooth and 20-tooth ALPHA Disc pulley wheels with composite teeth for longer lifespan and quieter chain operation, while full aluminum discs minimize the risk of snagging on stones or mud.
At the center of the ALPHA Disc pulley wheels is the patented Active Debris Remover (ADR) bearing protection technology, which, thanks to its stainless steel dust cover and special grooving, expels contaminants away from the bearing as it rotates. Combined with hand-built hybrid ceramic bearings, the system offers exceptionally low friction, high efficiency, and long-term durability. The redesigned and reinforced cage, inspired by the road OSPW RS systems, is engineered to withstand the extreme demands of gravel and MTB riding.
The net weight of the system is 127g. The package includes the complete OSPW ALPHA system for Shimano GRX/XTR/XT 12S Di2.
