Rotor Double tray aero round ring bcd110x4 50t(34) outer

These aero rings were designed as a solution for people who want the quality of ROTOR chainrings but are not ready to change their entire band from a standard AXS setup. Made of 7071 aluminum, these are the best chainrings you can buy. They offer all the benefits of ROTOR chainrings in a clean, crisp, aerodynamic package. Pedal harder, push further and go faster with less effort.
