For ultimate in single ring performance, throw the new Rotor QX1 MTB 'Q-RINGS' on your 104bcd single speed cranks. You’ll be using the same chain ring set up that led Christoph Sauser to victory at the Cross Country Marathon World Championships.
The QX1 has an increased ovality of 12% to help you accelerate better, feel less muscle fatigue, experience smoother torque and better grip off road.
The alternating thick/thin tooth profile keeps your chain from dropping in even the worst conditions, eliminating the need for a chain guide or tensioner.
It is compatible with all 104 BCD cranks (Shimano fitment)
