What Our Gearhead(R) Experts Are Saying: "I switched to the Rotor Q-Rings 9000/6800 on my endurance road setup and noticed smoother pedal strokes and less fatigue on longer climbs. The oval design feels natural once dialed in, and the multiple OCP positions let me fine-tune my setup for optimal power transfer."We're always chasing marginal gains, and the Rotor Q-Rings chainring helps us find them-especially when the road points up. Designed to fit Shimano 9000 and 6800 cranksets with a 4-arm 110mm BCD, this chainring transforms our pedal stroke for better power delivery and efficiency on long-distance rides.
