These aero rings are built for a 2x drivetrain to keep it sleek without giving up your front derailleur. You get all the benefits of stiff chainrings in a neat, clean-shifting, aerodynamic package, and the 110x4 BCD aligns with general industry standards for cross-brand compatibility.
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.
