QXL Outer Chainring

Rotor Bike Components' success with ovalized chainrings is evident, as it continues to expand its line by incorporating varying levels of ovality to its rings. Doing so has proven to optimize pedaling efficiency for different rider profiles. The QXL Outer Chainring was designed for riders who ride on the rivet and race in conditions that require extra high power output.


Time-trials, sprints, and breakaways often require extended periods of high power output. And while Rotor's Q Rings are capable of handling the power load and torque, the QXL rings feature 16% ovalization as compared to the Q-Rings' 10%. What does an oval ring do you ask? Well, they are essentially designed to maximize the efficiency of your pedal stroke by prolonging the power zone and minimizing dead spots. They are machined out of 7075 aluminum and, with multiple mounting holes, can be "clocked" to maximize the effects for your biomechanics, pedaling style, and bike geometry. The higher ovality of the QXL rings makes them ideal for the high cadence, high power rider such as a sprinter.


QXL rings feature five OCP points. These points allow you to position the rings to maximize efficiency of your individual riding style. As mentioned, you "clock" them, meaning that you turn them in relationship to the spider so that the dead spot in your pedal stroke is minimized. Not every rider will have a dead spot at exactly the same spot on the stroke.


The Rotor QXL Outer Chainring is available in the sizes 110mm/52t, 110mm/53t, 130mm/53t, 130mm/54t, and Shimano 46t, 52t, 53t, and 54t. They come in Black.
