*Coated bearings

SRAM’s 1x Eagle component system boasts a twelve-speed cassette. We have built pulleys that can handle the load better than stock. These CeramicSpeed Pulley Wheels work with less friction, adding to the power transmitted to the rear wheel, and greater durability, too, going longer between replacement intervals.

These pulleys are also fully compatible with the SRAM Eagle AXS derailleur. 

The upper and lower pulleys both have a narrow-wide tooth design. Both pulleys have 14 teeth.

When you go with these, you need to choose between three options. Machined aluminum pulleys with our CeramicSpeed Balls in stainless steel-races. These win efficiency tests everywhere, dominating the manufacturer’s pulleys. The second has aluminum pulleys with our CeramicSpeed Balls in coated hardened-steel races. Third is machined titanium pulleys with our standard CeramicSpeed Balls installed in coated, hardened-steel races.

In the box

  • 2 x 14-tooth pulley wheels.
  • CeramicSpeed Bearing Oil in 15ml dropper bottle.
  • CeramicSpeed Grease in 5ml syringe.
  • Sticker sheet.

The aluminum pulleys with standard bearings are 34.4% more efficient than stock.

The machined titanium pulleys have three times the life of machined aluminum.

The Coated Bearings reduce friction beyond our standard bearings. The reduction is over 50%. The coated have races 75% harder than our hardened-steel races and that helps them last 60% longer than our standard bearings. Friction is decreased by over 50% compared to our standard bearings.

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 pulley 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 oiled. The grease is for particularly harsh environments.
