These aero rings are built for a 1x drivetrain, which is about as aero as you can get without taking the cranks out altogether and making a pushbike. You get all the benefits of oval chainrings in a neat, clean-shifting, aerodynamic package, without the hassle of a front derailleur. These chainrings are the ideal solution for an aerodynamic drivetrain. 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. Also works great as a 1x solution for most Shimano 110x4 asymmetric cranks.
For peak aerodynamics and aesthetics, these rings are best paired with the aero crown.
