CeramicSpeed OSPW RS Alpha V3 SRAM Red AXS D1/E1 + Force AXS D1
CeramicSpeed OSPW RS Alpha V3 SRAM Red AXS D1/E1 + Force AXS D1 Info
The CeramicSpeed OSPW RS Alpha V3 SRAM Red AXS D1/E1 + Force AXS D1 is CeramicSpeed's oversized pulley wheel system built for SRAM's Red and Force AXS electronic groupsets. It replaces the stock rear derailleur cage and pulleys with larger 15-tooth and 19-tooth pulleys running on hand-built, low-friction bearings, aiming to cut drivetrain resistance while giving the rear derailleur a more contemporary, angular look that matches current bike and groupset design trends.
This V3 version carries over CeramicSpeed's ALPHA Disc pulley wheels — a two-piece design pairing a narrow-wide tooth profile in composite material, for wear resistance and quieter running, with a solid aluminum disc that closes off the gaps between spokes on a traditional pulley wheel. That solid disc keeps debris, mud, and small objects from working into the mechanism while adding stiffness to the wheel. It's paired with CeramicSpeed's patented ADR technology, which anchors a dust cover in a groove around the bearing and surrounds it with a bladed groove structure that flings debris away as the pulley spins — a system CeramicSpeed field-tested with sponsored cyclocross teams during the 2022 World Cup season to prove out mud clearance.
What's new in V3 is an optimized cage interface, designed to make installation faster, easier, and more consistent than earlier OSPW RS generations, without changing the proven efficiency of the platform. It also carries adjustable spring tension so you can fine-tune cage preload and shifting feel to your specific Red or Force AXS setup, and CeramicSpeed backs the complete system with a lifetime warranty when built with ALPHA pulleys.
The premise behind any OSPW system is that larger pulley wheels reduce how sharply the chain has to bend as it wraps around them, lowering friction through the drivetrain. CeramicSpeed doesn't publish a specific wattage figure for this model, so the honest way to frame it is a friction-reduction upgrade rather than a guaranteed number of watts saved.
At $699.00, this is an upgrade for riders who already understand what an OSPW system does and want it paired with Red or Force AXS specifically — it's not a component most riders reach for on a whim. It suits cyclists chasing marginal drivetrain efficiency and a cleaner, more integrated look at the rear derailleur, particularly those riding in conditions where the ALPHA Disc and ADR debris protection will actually get used.
