Maximum efficiency for your SRAM AXS drivetrain, in every condition

The OSPW RS ALPHA for SRAM RED D1/E1 + Force D1 v3 is an exceptionally efficient pulley system, built for long-lasting performance in all conditions. The 15-tooth + 19-tooth oversized pulleys, together with hand-built low friction bearings, reduce drivetrain resistance and improve overall performance. The updated design blends the OSPW system seamlessly into today's bike and groupset aesthetics, without losing the identity that defines every CeramicSpeed product.

V3: easier install, same proven efficiency
The new V3 version introduces an optimised cage interface that makes installation faster, easier and more consistent — while keeping the efficiency and durability that define the OSPW RS platform.

Patented ADR: the bearing stays protected
Active Debris Remover (patented ADR technology) pairs a new dust cover — anchored in a groove in the pulley wheel — with a bladed groove structure that actively extracts debris while the pulley spins. The bearing stays fully enclosed and protected, refined through CeramicSpeed's R&D lab and field testing with professional off-road teams.

ALPHA Disc: built for the mud
Available with the ALPHA Disc pulley wheel, proven during the 2022 CycloCross World Cup season: a narrow-wide composite tooth profile for extended wear and quieter running, plus a solid aluminium disc that stops debris jamming between the spokes and adds stiffness.

Compatibility
Compatible with SRAM RED D1, RED E1, Force D1 and Force D2 road derailleurs (not XPLR).
