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.

There are choices, so you can choose for your needs. Machined aluminum pulleys with our CeramicSpeed Balls in stainless-steel races is the base. The bearings are our Standard Bearings. These test better than anything else on the market. The second option is machined titanium pulleys with our Stock Bearings. The third is machined titanium pulleys with our CeramicSpeed Balls installed in coated, hardened-steel races.
