SRAM's 1x Eagle component system boasts a twelve-speed cassette. We built pulleys that can handle the load better than stock. These CeramicSpeed Pulley Wheels work with less drag, adding to the power transmitted to the rear wheel while offering greater durability, going longer between replacement intervals.
These pulleys are also fully compatible with the SRAM Eagle AXS derailleur.
The aluminum pulleys with standard bearings are 34.4% more efficient than stock and use our low-drag, long-life Standard Bearing with hardened-steel races and our super-round CeramicSpeed balls. The upper and lower pulleys both have a narrow-wide tooth design with 14 teeth each. As the upper and lower pulleys have different tasks, they have different shapes. You'll find they are thus marked, and have directional arrows.
These pulleys should be installed with stock SRAM pulley spacers. Save those from your old pulleys before installing CeramicSpeed.
The kits come with CeramicSpeed Oil in a 15ml dropper bottle and grease in 5ml syringe. The bearings come pre-oiled. The grease can be used on the pulley bearings when riding in particularly harsh environments.
In the box:
- 2 x 14-tooth pulley wheels
- CeramicSpeed Bearing Oil in 15ml dropper bottle
- CeramicSpeed Grease in 5ml syringe
- Sticker sheet
