Saving watts is just the beginning with the Rotor Aero Round Outer Ring. Built for 110 BCD Rotor 4-bolt crank the aero outer ring is engineered to be incredibly stiff and offer an aero advantage over traditional designs. The ring uses cut-outs and a ramped shape in the aluminum to redirect airflow in a smooth pattern.
