OSPW RS ALPHA for Shimano 9250/8150 TEAM Logo
The OSPW RS ALPHA Team Edition is the ultimate statement piece for a top-tier Shimano 12-speed build. It combines the aerodynamic and structural benefits of the solid ALPHA Disc pulleys with the bold aesthetics of CeramicSpeed’s professional sponsored teams. Beyond the oversized branding, this system is a technical powerhouse featuring Active Debris Remover (ADR) technology and a reinforced, angular cage that is significantly stiffer than previous generations. The solid disc pulleys are designed to be "clog-proof," making this the ideal upgrade for riders who demand WorldTour performance and visibility, whether they are racing on clean tarmac or tackling the grit of a spring classic.
Key Features
-
Team Edition Aesthetics: Features a massive, high-contrast white CeramicSpeed logo across the cage for maximum brand visibility and a pro-peloton look.
-
ALPHA Disc Pulley Wheels: Solid aluminum discs eliminate the spokes where road grime or branches could catch, while composite teeth ensure silent, smooth shifting.
-
Active Debris Remover (ADR): A patent-pending bladed dust cover system that uses centrifugal force to spin mud and water away from the ceramic bearings.
-
Enhanced Cage Rigidity: The "Racing Sport" (RS) cage is reinforced with carbon-fiber-filled polyamide, providing new levels of durability and shifting precision under high torque.
-
Unmatched Efficiency: Handbuilt ceramic bearings reduce friction and save significant wattage compared to the standard Shimano 12-speed pulley wheels.
