Product Description
These aero rings are built for a 2x drivetrain to keep it aero without giving up your front derailleur. You get all the benefits of oval chainrings in a neat, clean-shifting, aerodynamic package, and the 110x4 BCD aligns with general industry standards for cross-brand compatibility. Pedal harder, push farther, and go faster with less effort.
The 110 BCD 4-bolt asymmetric bolt pattern is compatible with all ROTOR modular cranks and power meters including 2INpower, INpower, INspider, ALHDU, and VEGAST.
For peak aerodynamics and aesthetics, these rings are best paired with the aero crown.
