CERAMICSPEED OSPW RS ALPHA Special Edition pulley for SRAM RED/FORCE AXS

We are excited to present our first special edition of the OSPW RS system. The new versions Silver and Niro offrono un'estetica pulita e moderna, con un elemento grafico distintivo nella gabbia del cambio.

The dark design Niro è abbinato a pulegge ALPHA Disc nere, mentre la versione argentata Silver introduces ALPHA Disc pulleys in silver finish.

Compatible exclusively with the SRAM Red E1 AXS groupset. Not compatible with SRAM Force E1/Rival E1.

With the OSPW RS dedicated to SRAM road groupsets, we have pushed our oversized pulley system into the future with a modern, angular design. The new aesthetic adds balance and refinement, integrating perfectly with current trends in frame and groupset design, of which the OSPW is an integral part.

Optimized shifting performance

Active Debris Remover (ADR)
ADR is an innovative, patent-pending technology that effectively prevents debris from entering the bearing.

features a new dust cover that anchors securely into a groove on the pulley, completely enclosing the bearing. This is paired with a blade-groove structure that, during pulley rotation, dynamically expels debris.

ADR is the result of continuous development involving our Research & Development department, the CeramicSpeed test laboratory and field feedback from our professional off-road teams.

ALPHA Disc
The new OSPW RS is equipped with the extremely durable ALPHA Disc pulleys, first introduced in the OSPW X system for the Eagle drivetrain.

The ALPHA Discs are built with a two-component structure: a narrow-wide toothed profile in composite material, which ensures durability and reduces noise, and a solid aluminum disc that prevents foreign objects from entering between the pulley spokes, while at the same time increasing strength and rigidity.

The first versions of this design were tested during the Cyclocross World Cups. In the 2022 season, the Tormans team successfully adopted this system even in the most extreme muddy conditions.

New design: improved quality and durability
The new OSPW RS is not just an aesthetic update. The cage has been reinforced to offer superior robustness and durability.
