ROTOR QRINGS 39 - 130 BCD X 5 BLACK

Q-Rings are oval chainrings which provide variable gear ratios through the pedal rotation optimizing your legs ability to deliver power while reducing the negative effects of the dead spots.

pedal rotation providing a lower gear ratio at the dead spots

which improves your knee comfort. OCP SYSTEM (Optimum Chainring Position) enables you to choose the angle where you obtain the maximum benefit and comfort, customized to your personal pedaling style. Q-Rings increase your efficiency, enabling you do perform

better when you need it most: climbing, sprinting, etc.
