Rotor Aero Q Ring 110BCD Outer 55T Oval Chainring
The Rotor Aero Q Ring Outer 55T Oval Chainring has a 4-bolt, 110BCD mounting format to make it compatible with modular Rotor cranks and cranks from Shimano like the Dura-Ace FC-R9100 and Ultegra FC-R8000 models. Used as part of a double chainring configuration, its precision CNC machined 7075 aluminium construction affords excellent stiffness for efficient power transfer and positive gear changes. In addition, its oval format helps the rider improve their pedalling action and economy, and the solid aero format reduces drag at higher riding speeds.
