ROTOR Q-Ring Cyclocross CX1
Based on ROTOR's signature Q-Rings, QCX1 rings are compatible with all BCD 110 cranks, especially ROTOR's 3D+ and 3D30 cranks. Because of the OCP System installation does not require disassembling the crankset from the bike, making ideal gear selection easier. A specific alternating thick/thin (narrow wide) tooth profile does not allow the chain to drop off even in the worst conditions, with no need for a chain guide.
The oval Q-Rings offers unparalleled stiffness and outstanding aerodynamic, hence they are perfectly suited for triathlon and time trial. Furthermore these chainrings increase your power by emulating a Rotor System crankset in the power stroke and by minimizing the intensity of the "dead spot" zones. By extending the time you spend in the power stroke (where 90% of all power is produced) and smoothly accelerating the legs through the critically weak "dead spots".
The Q-Ring design provides smooth and uniform pedaling without sudden accelerations or shifting problems. It increase and decrease the gear ratio throughout each pedal rotation providing a lower gear ratio at the dead spots which improves your knee comfort.
The patented Rotor OCP system (Optimized Chainring Position) enables you to choose the angle where you obtain the maximum benefit and comfort, customized to your pedaling style.
The Aero Q-Rings made of 7075 T6 aluminium. The hard-anodized surface offers a nice looking finish with high durability.
