The World's Fastest Pulley Wheel System Just Got Faster

The CeramicSpeed OSPW Aero for SRAM Red/Force AXS 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 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 customized setup based on riding conditions.

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

  • Reduces aerodynamic drag on the rear derailleur by up to 60%
  • Co-developed with Drag2Zero
  • Chosen by World Champions
