Rotor Q-Rings help overall endurance and performance by reducing the dead spots while riding. The oval shape allows for your legs to create a smoother and more effective pedaling stroke.

How It Works:

Rotor Q-Rings allow for easier moving of the legs through dead spots creating the feel of a smaller circular chainring and enabling your legs to remain in the power stroke for a longer periods of time.

Q-Rings change the equivalent tooth size by decreasing it before the dead-spots and increasing it when the rider is at the pedal down stroke.

For example a 53T Q-Ring is equivalent to a 51T around the upper dead-spot but when power is applied and the pedal goes down the equivalent chainring tooth size reaches 56T allowing for longer power strokes.

About Chainrings

Chainrings are fitted to the crank arms and come in single, double or triple configuration. Most geared bikes use a 3/32 inch width, whereas 1/8 inch is the popular choice for track bikes and some single speeds due to its increased strength which is needed when riding a fixed wheel. Chainrings are available in a number of formats, these are known as PCD's (Pitch Circle Diameter) or BCD's (Bolt Circle Diameter), this is the spacing of the bolts that secure the rings to the crank arms. Common sizes are 74mm inner ring Shimano MTB, 110mm middle and outer for Shimano MTB, 110mm for most compact chainsets to allow for the smaller ring combo's, 130mm for Standard Shimano Road and 135mm for Standard Campagnolo road chainsets.
