The ROTOR Q-Ring 110×4 Aero Oval Outer Chainring (54 T) is a performance-oriented oval chainring engineered for road use. CNC-machined from 7075-T6 aluminum, the Aero version is shaped to improve aerodynamics and lateral stiffness. Featuring 12.5 % ovality and three Optimum Chainring Positions (OCP), it's designed to reduce pedaling inefficiencies and enhance power delivery. Compatible with Shimano and ROTOR 110×4 cranksets, this chainring balances speed, stiffness, and precise shifting.
