Description of Rotor QXL-Rings 5-arm 130 BCD Aero Road Chainring oval

QXL-Rings are more oval than the known Q-Rings. The whole chain ring has a ovality of 16%. The aero-style design of Rotor’s oval QXL-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 QXL-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 QXL-Rings made of 7075 T6 aluminium. The hard-anodized surface offers a nice looking finish with high durability. 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.
