Rotor | Qxl 4 Bolt Road Chainring 110Bcd 52Ax110X4 Shimano | Aluminum

Rotor Qxl 4 Bolt Road Chainring 110Bcd 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 Through Rotor's Optimum Chainring Position (OCP) you have approximately 5 degrees of adjustment meaning you can micro adjust the position of your Q Rings to suit your style by simply making corrections toward both comfort and efficiency. Machined from 100% CNC T6 7075 Aluminum, the cyclocross specific 4 bolt Q-Ring set comes in a 46/34 pairing option, while the road aero/TT specific rings are available in 50/34, 52/36, 53/38 and 54/44 options, and are compatible with 4 bolt crankarms and spiders.
