Rotor Outer Q-Ring Chainring BCD110X4

Rotor Outer Q-Ring Chainring BCD110X4

The Rotor Qring Inner Chainring 110BCD 4Bolt has been designed to fit Shimano 4-bolt compact cranks. It features a subtle, yet efficient 10% ovality where the smallest diameter is at its weakest point of the pedal stroke. The Shimano aero Q-rings offer 3 optimum chain ring positions (OCP)) that can be adjusted to take advantage of your pedal stroke’s most efficient zone.

Rotor Q-Rings vary drivetrain resistance during a pedal rotation to align with your leg’s natural strength spots and weak spots to boost your overall efficiency. In doing so, Q rings wisely utilize the strongest muscle groups to increase positive work, while picking up the slack in the weaker zones to reduce the negative work, potentially increasing a competitive cyclist’s performance by as much as 4 seconds per km in an all-out sprint. That may sound miniscule, however it’s twice the benefit of an aero wheelset, and in a sport where a second can be the difference between the top step of the podium and no podium at all; these proportions are substantial.
