Restore that crisp, friction-free shift to your SRAM RED eTap AXS drivetrain with genuine ceramic-bearing pulley wheels. A worn or grit-clogged pulley set costs you watts and shifting precision, and this OEM kit brings both back while shedding a few grams over steel-bearing replacements.
Highlights
- Genuine SRAM RED-level ceramic-bearing pulley wheels for lower drivetrain friction
- Complete set: 12-tooth upper and 12-tooth lower pulleys
- Includes both titanium pulley bolts (18.5mm upper, 12.8mm lower) and grease
- Direct replacement for the SRAM RED eTap AXS 12-speed rear derailleur
Smoother shifting, less drag
The ceramic bearings spin with less resistance than standard steel cartridge bearings, so the chain articulates more freely through the derailleur cage. The result is quieter running under load and a small but real efficiency gain — the kind of marginal detail RED riders chase.
Complete, ready-to-fit kit
Both pulleys arrive matched with the correct titanium hardware: the longer 18.5mm screw for the upper (guide) pulley and the shorter 12.8mm screw for the lower (tension) pulley, plus grease for reassembly. Titanium bolts keep weight down without compromising the cage interface.
Compatibility and fit
Designed for the SRAM RED eTap AXS 12-speed rear derailleur. The pulley wheels are 12-tooth, matching the standard cage on the road RED eTap AXS derailleur (10-26T up to 10-36T cassettes). Take care to fit each pulley and its dedicated screw in the correct position — upper and lower screws differ in length and are not interchangeable.
