Rotor created Q-Rings 110BCD and 130BCD from the concept that you could pedal more efficiently if only you could take greater advantage of your maximum power effort while lessening the time spent in the dead spots of a pedal rotation. Subtle but efficient 10% ovality and compatible with your standard 110BCD or 130BCD cranks, Q-Rings unprecedented orientation factor yield an improved pedal stroke marked by performance.
Many professional riders have successfully used oval chainrings for years and know about Q-Rings’ advantages. Q-Rings simulate a higher gear at the point of maximum force, i.e. the most productive part of the pedal stroke, and therefore leverage the power phase. In the pedal rotation’s dead spot, where we exert the least force, a simulated smaller gear enables us to more easily overcome this dead spot. In addition, Q-Rings feature up to 5 Optimum Chainring Positions (OCP) that can be oriented around a cyclist’s distinct pedalling characteristics.
