Product details

With the oval Q-Rings chainrings from Rotor, you can ride longer and faster with less fatigue because you use your power more efficiently. The Q-Rings adjust the resistance while pedaling according to the natural strengths and weaknesses of your legs.

The oval chainrings are compatible with Rotor Direct Mount (DM) cranks as well as 4-bolt Shimano cranks. When mounted on Rotor DM cranks, these Q-Rings can be adjusted in 1-degree increments. When mounted on Shimano cranks, the chainrings are set in the OCP3 intermediate position, which is the most commonly used position by road cyclists. For perfect aesthetic integration with Shimano cranks, a set of screw covers is available for the various crank models.
