On fast road sections, gearing that suits your drivetrain matters. The ROTOR Round Rings 44-tooth inner chainring complements performance 2x road drivetrains with BCD 110x4 mm and is designed for pairing with compatible outer chainrings with 54, 55 or 56 teeth.

Thanks to its round chainring shape, the gear ratio remains constant throughout the crank revolution. The CNC-machined 7075-T6 aluminum provides a precisely manufactured base for your road drivetrain. When installing, check the specific four-arm bolt pattern and intended chainring combination, as well as the bolt circle.
