Incredibly Stiff — Round Or Oval For Road 2x

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.

Crankarm Compatibility:

  • Rotor Aldhu
  • Rotor Aldhu24
  • Rotor Vegast
  • Rotor INpower DM
  • Rotor 2INpower DM
  • A Fully Customizable Crankset Approach

    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.

    Features:

  • Aerodynamic chainring for Rotor cranks
  • Designed as part of Rotor's modular crankset system
  • Aluminum material is strong without a weight penalty
  • 110 BDC 4-bolt can fit more than just rotor cranks
  • Available in round or oval profile
  • Available in 34t up to 52t, inner and outer-specific variants
