Rotor Cyclocross Q Ring Chainring

Ovalized chainrings for maximum performance.

There’s a breed of racer who thrives in weather deemed ugly by others; who craves the blinding high of forcing the body to the brink of its limits; who sometimes sees stars because the legs won’t quit stomping out dizzying wattage on the pedals; and who is so hooked on cyclocross that other race formats only serve to train for ‘cross. We’ve made QCX1 rings for this racer. Based on ROTOR's signature Q-Rings, QCX1 rings are compatible with all BCD 110 cranks, especially ROTOR’s 3D+ and 3D30 cranks. Installation does not require disassembling the crankset from the bike, making ideal gear selection easier. A specific alternating thick/thin, single-speed tooth profile does not allow the chain to drop off even in the worst conditions, with no need for a chain guide.

Why Q-Rings?

Q-Rings boost your performance by varying drivetrain resistance during pedalling in line with your legs natural strengths and weakness. They make better use of the strongest muscle groups (increasing positive work) and compensate for the weaker zones in the pedalling stroke (reducing negative work).

A Q-Ring gives a silky-smooth “perfect spin” by smoothening out torque variations and making better use of your strongest muscles
