CeramicSpeed OSPW RS 5-Spoke V3 SRAM Red AXS D1/E1 and Force AXS D1

The CeramicSpeed OSPW RS 5-Spoke V3 SRAM Red AXS D1/E1 and Force AXS D1 is CeramicSpeed's lighter-weight take on its oversized pulley wheel system for SRAM's Red and Force AXS groups. Where the Alpha Disc versions use a solid pulley disc, this system uses an open 5-spoke aluminum design that trims weight while still running CeramicSpeed's low-friction bearing technology underneath. It's available in four colorways — black, red, gold, and blue — so riders can match the system to their bike rather than being limited to a single finish.

The system runs 15-tooth and 19-tooth oversized pulleys, and the 5-spoke aluminum construction brings the complete system down to 85 grams net, noticeably lighter than CeramicSpeed's solid Alpha Disc pulleys. Each pulley spins on hand-built CeramicSpeed bearings, protected by the brand's Active Debris Remover (ADR) technology — a dust cover and bladed groove structure that actively pushes dirt and grit away from the bearing rather than relying on a static seal. That's the same bearing protection used across CeramicSpeed's higher-priced Alpha pulleys, just paired here with a lighter, more open pulley design.

This is the V3 revision of the platform, and the update centers on the cage: CeramicSpeed reworked the cage interface for a faster, more consistent installation onto Red and Force AXS derailleurs. The system is compatible with SRAM's UFO Ultra Endurance and UFO Speed 12-speed flattop chains, and CeramicSpeed backs the complete OSPW RS system with a lifetime warranty.

This is the pick for a SRAM Red or Force AXS rider who wants CeramicSpeed's low-friction bearing gains and a lighter overall system without paying for the solid Alpha Disc pulleys — and who likes having a colorway to choose from beyond black.
