ROTOR Q CHAINRINGS 50 110 BCD
Rotor Q-Rings increase your power 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.
Q-Rings are 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. Rotor Q-Ring technology convinces many professional cyclists. The Cervélo Test Team uses Rotor cranksets with Q-Rings on their bikes.
