Rotor QXL SH-110 Chainring.
- Specific to Shimano 9000/6800 4x110mm BCD cranks
- QXL's 16% ovalization is for riders seeking greater biomechanical advantage (ideal for riders who already have experience on Q-rings with 10% ovalization)
- Best suited for time-trials, sprints and riders who frequently pedal out of the saddle
- Optimum Chainring Position power tuning feature: 3 OCP settings (2,3,4)
- Made in Spain from CNC machined 7075-T6 aluminum with steel pins
- Aerodynamic shape also adds stiffness
