SRAM’s 1x 11-speed rear derailleurs work better with our 12-tooth pulleys. They work with less mechanical friction, adding to the power transmitted to the rear wheel. They also possess greater durability, going longer between replacement intervals.

Our Pulley Wheels for SRAM 1-11 are compatible with the following 11-speed rear derailleurs:
Force CX1
Force 1
Rival 1
Apex 1
XX1 MTB
X01 MTB

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

The machined titanium pulleys comes with CeramicSpeed Balls installed in coated, hardened-steel races that adds an extra layer to the performance of the product and and offer even longer lifetime and lower friction.

Tech data

Machined aluminum pulleys are the standard by which we measure. Machined titanium lasts three times longer.

The Coated Bearings have races 75% harder than our Standard Bearings. They have a life 60% longer than our Standard. Frictional drag decreases by over 50% compared to our Standard.

There are different upper and lower pulleys, are marked, and have directional arrows.

These pulleys need to be installed with stock SRAM pulley spacers between the cages. Save those before installing CeramicSpeed.

The kits come with CeramicSpeed oil in a 15ml dropper bottle and grease in 5ml syringe. The bearings come oiled. The additional oil is for maintenance. The grease for harsh environments.
