Rotor qxl external road chainring 110mm bcd 4 holes black

increased ovalization the new rotor qxl is a q ring with increased ovalization they have a similar shape to standard qrings ensuring exceptional drivetrain stability qxl rings do not replace standard q rings rather complement them as each is optimized for different rider profiles and situations we believe that standard q rings offer an optimal adaptation stability biomechanical balance for most cyclists however we are aware of scientific research and feedback from pro riders that shows that greater ovality can be desirable and useful for certain athletes since not all riders have the same muscle build riding form or pedaling style features 100 cnc aluminium 7075 t6 aero design stiffness and aerodynamic advantage 3 ocp settings 2 3 4 availability 54 44 53 38 52 36 46 36
