Description

The ROTOR ROUND AERO 110 mm 12-speed outer chainring is designed for modern 2x road drivetrains where efficiency and aerodynamics matter. Its round shape and AERO profile help deliver smooth pedalling while keeping weight down, making it ideal for performance-focused cyclists.

Compatible with all ROTOR cranksets using a BCD110x4 spider, this chainring works with Shimano® 2x12 and 2x11 groupsets and the INspider® power meter. It delivers fast, precise and quiet gear changes.

This chainring is also compatible with Shimano® Dura-Ace®, Ultegra® and 105® cranksets. It offers a reliable alternative for cyclists who prefer round chainrings to Q RINGS®.
