Rotor Q-Ring 52T 110 BCD Road

The engineers at Rotor Bike Components developed their original Rotor Crank to maximize the efficiency of your pedal stroke by prolonging the power zone and minimizing dead spots. With these ovalized Road Outer Q-Rings, you can have the majority of the benefit of the Rotor crankset, but you can use the crank of your choice (Shimano, Campy, SRAM, et al). And with redesigned shift pins and ramping, Q-Rings shift without hesitation.

Any assumptions that this is rehashed Biopace are wrong. To the contrary, Rotor Road Outer Q-Rings will help you produce more power and reduce fatigue. They capitalize on the strongest part of your pedal stroke and minimize the negative effects of dead spots. The Q-Rings have a subtle oval shape and, with multiple mounting holes, can be 'clocked' to maximize the effects for your biomechanics, pedaling style, and bike geometry.

The Q-Ring's oval shaping smoothes the pedal stroke through the dead spots and takes advantage of your power potential at the optimum time -- in the power zone. The multiple mounting hole system is called OCP (Optimum Chainring Positioning) and it allows each rider to maximize the benefit of the Q-Rings.

The long axis of the oval chainring should be vertically aligned in the power zone when the crankarms are at or just below horizontal. This position gives the rider maximum leverage, and therefore maximum torque transmission to the rear wheel. Inversely, the short axis of the chainring is aligned so that it nears the vertical when the crankarms are also close to vertical.

The short axis of the oval creates a shorter lever when you make less power. The effect is a subtle acceleration of the legs through the top and bottom of the stroke and less muscle strain at these traditionally weak points in the cycle. With Q-Rings, you'll put more power to the ground while taxing your muscles less.

Rotor Road Outer Q-Rings are made with hard anodized CNC machined 7075 aluminum. They are available with a black finish. They fit Rotor Agilis and 3D Cranksets and are also compatible with most every crankset and BCD (bolt circle diameter) currently available -- 110mm compact, 113mm Campagnolo compact, 130mm standard, and 135mm Campagnolo standard. They come with 46, 48, 50, 52, and 53 tooth counts.
