ROTOR QXL External Road Chainring 110mm BCD 4 Holes Black

Increased ovalizationThe 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.
