The Oversized Pulley Wheel System for SRAM Red and Force AXS features a 15-tooth upper and 19-tooth lower pulley wheel setting, for maximum efficiency. The handbuilt OSPW System has two spring tension settings, that allows customised setup based on riding conditions.
This OSPW 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.
