Saving watts is just the beginning with the Rotor Aero 110x4 Rings for Road 2x. Built for 110 BCD Rotor 4-bolt crank the aero rings are engineered to be incredibly stiff and offer a pronounced aerodynamic advantage over traditional designs. The ring uses cut-outs and a ramped shape in the aluminum to redirect airflow in a smooth pattern.
Optimum Chainring Position (OCP) Mount technology allows the rider to fine-tune the orientation of ROTOR's oval Q Rings by shifting them one degree at a time, finding the right balance in each pedal stroke for smooth power.
Here's how Rotor's new cranksets work — everything is modular. You choose the arms, the spindle, and the chainring. And whether you want a power meter-equipped spider, spindle, crankarm, or none of that. You can even choose between round and oval chainrings. Then piece it all together to create the exact system that suits your specific needs.
