Description of Rotor Q-Rings XC2 SRAM MTB Chainring 4-arm 120/80mm

Oval Rotor SRAM XC2 Q-Rings especially designed for SRAM 2-speed cranksets 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 wich improves your knee comfort. The aero-style design of the XC2 SRAM MTB chainrings offers unparalleled stiffness with a competitive weight.

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.

Q-Rings are made of 7075 T6 aluminium. The hard-anodized surface offers a nice looking finish with high durability. Equipped with steel shifting pins. The application of Rotor's latest generation of tooth profiles, ramps and pins guarantee problem free, slick and fast shifting operations during all weather conditions
