Ceramicspeed OSPW Aero for SRAM Red/Force AXS

The world’s fastest Pulley Wheel system just got faster. OSPW Aero features a lifetime warranty and is wind-tunnel tested to have 40% less friction compared to a stock derailleur, making it perfect for time trials or triathlons.

The OSPW Aero is an industry-leading product co-developed with one of the world’s leading aerodynamicists; Simon Smart and is chosen by World Champions and top athletes around the world. This OSPW system has handbuilt CeramicSpeed Bearings installed and its unique design and craftsmanship will captivate you from the first time you use it.

The system features a 15-tooth upper Pulley Wheel and a 19-tooth lower Pulley Wheel to provide absolute optimization of the rear derailleur and the upper and lower oversized aluminum Pulley Wheels come fitted with coated CeramicSpeed Bearings that have been perfected through years of experience. The handbuilt OSPW Aero System has two spring tension settings, that allows customised setup based on riding conditions.

This OSPW Aero System is also compatible with the 2020 11 speed SRAM Red eTap derailleur featuring a clutch.

Note; While there are visual similarities with the SRAM RED/Force AXS derailleurs, this OSPW system is not compatible with the SRAM Rival AXS derailleur. Please see here for our SRAM Rival AXS compatible OSPW System. If you have a SRAM Red, Force, or Rival XPLR eTap AXS derailleur, please see our Pulley Wheels for SRAM AXS Road.
