The ROTOR Aero Round Ring 56T is a round outer chainring for fast 2x road bike setups with an aggressive 56/44-tooth gear ratio. With 56 teeth, this version is especially suited to riders who prefer a high gear and direct response at high speeds.
The enclosed aero design creates a clean look and is particularly well suited to performance-oriented road and time trial setups. The BCD 110x4 mounting and specified pairing with a 44T inner chainring clearly define the crankset and chainring configuration this model is designed for.
