Round ring 1X Aero BCD110x4 12-11s
The ROTOR Round rings 1X Aero BCD110x4 are compatible with 12-11s speeds groupsets. In combination with our Aero MAS Spider, these chainrings deliver minimal air resistance, reducing drag and allowing you to pedal faster with less effort.
Made from CNC-machined 7075 T6 aluminum alloy, they are extremely light and stiff. With a weight of just 68.7g for the 40T, 108.6g for the 46T and 212g for the 60T, offering one of the best stiffness-to-weight ratios in the market for a 1X aero chainring.
Furthermore, they are compatible with all ROTOR modular road and gravel cranks and power meters, including 2INpower, INspider, INpower, ALDHU, and VEGAST, as well as with any of our 110x4 spiders. This allows you to fully customize your drivetrain assembly.
