For ultimate in single ring performance, throw the new Rotor QX1 110 BCD 'Q-RINGS' on your ROTOR 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 12.5% to help you accelerate better, feel less muscle fatigue, experience smoother torque and better grip.
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.
110BCD ring option - Please note QX1 110BCD rings will fit any Shimano/SRAM/FSA cranks with a 5 arm pattern. Pic shows 48T
