Product Description
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. 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, ALDHU, and VEGAST. Also a great 1x solution for most Shimano cranksets.
