OSPW ALPHA for Shimano GRX/XTR/XT 12S Di2 Platin

A metallic finish accentuates the technical character of the ALPHA Disc Pulley Wheels while a distinctive honeycomb graphic pattern draws inspiration from nature's most efficient structures, symbolising the perfect balance of strength, precision, and lightweight performance.

Featuring our patented bearing protection ADR (Active Debris Remover) bearing protection technology and hybrid ceramic bearings, this Special Edition delivers exceptional durability and efficiency while adding an elevated visual expression to these precision-engineered components.

Our latest offroad specific OSPW system for Shimano GRX, XTR, XT 12S Di2 derailleurs comes equipped with  14-tooth and 20-tooth ALPHA Disc Pulley Wheels. The composite tooth material offers prolonged wear protection and noise reduction - while the solid aluminum discs eliminate the potential of external objects getting stuck. 

Nestled in the ALPHA Disc pulleys is our patented Active Debris Remover (ADR) bearing protective tech feature. ADR combines a stainless-steel dust cover and a surrounding bladed groove structure that pushes contaminants away from the bearing when rotating. The pinnacle of efficiency and protection when paired with our hand-built hybrid ceramic bearings. 

The cage design was developed with inspiration from the OSPW RS road systems, combined with a commitment to functional strength, to exceed the harsh demands of off-road riding.
