The ROTOR Aero Round Ring 53T is a round outer chainring for sporty road and triathlon setups with a classic 53/39 gear ratio. With 53 teeth, this version is aimed at riders who prefer a high gear ratio and a direct, familiar pedaling feel on fast routes.

The closed Aero design creates a clean, uncluttered look and is especially well suited to performance-oriented road and time trial setups. Thanks to its BCD 110x4, the chainring is designed for compatible ROTOR and select Shimano 4-arm road cranksets.
