Rotors Q-Rings for 1x mountain bike drivetrains are designed to deliver the most productive pedal stroke possible. The 12.5% ovality can be oriented within 3 carefully designed optimum chaining positions. The results are an optimized down stroke that will save energy so you can outkick, outsprint and generally outlast the rider you used to be. This direct mount version is made to work specifically with Rotor's Hawk and Raptor cranksets. They feature a proprietary splined mounting system, and are easily swapped with the use of a 8mm allen key.
Narrow/Wide tooth profile keeps your chain from jumping off
100% CNC-machined, 7075-T6 aluminum alloy lightweight without sacrificing strength
3 OCP points (2-3-4) lets you choose the optimum position that works best for you
Designed to work with all 9, 10 and 11 speed groupsets
