Rotor QCX1 110 BCD Q-Ring (1x10/11 Set Up)
Based on Rotor's signature Q-Rings, the Rotor QCX1 110 BCD Q-Ring (1x10/11 Set Up) is compatible with all BCD 110 cranks, especially Rotor’s 3D+ and 3D30 cranks. The OCP System installation does not require taking the crankset off of the bike.
Furthermore this chainring increases your power by emulating a Rotor System crankset in the power stroke and by minimising 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 pedalling without sudden accelerations or shifting problems. It increases and decreases the gear ratio throughout each pedal rotation providing a lower gear ratio at the dead spots which improves your knee tracking.
The patented Rotor OCP system (Optimised Chainring Position) enables you to choose the angle where you obtain the maximum benefit and comfort, customised to your pedaling style.
The Aero Q-Rings are made of 7075 T6 aluminium. The hard-anodised surface offers a high quality finish with durability to match.
