Rotor QX1 Mountain Chainring

Rotor's QX1 Mountain Chainrings bring oval efficiency to the trail with durable construction and stiff power transfer that pairs perfectly with your Shimano XT M8000 and XTR M9000 crankset. Ovals aren't a new idea, but they've been gaining traction across disciplines with claims of boosted efficiency by minimizing dead spots through the pedal stroke. On trail, this translates to better acceleration, smoother torque, and improved grip through turns and berms. Additionally, the alternating thick and thin tooth profile keeps your chain from dropping even in the roughest conditions.Please note that these chainrings are specific to crankset, with slightly different cutouts designed to pair with the specified model.
