We carry a wide selection of ROTOR Chainrings for road, gravel, track and MTB cranksets. This includes 1x and 2x rings as well as both round and oval. ROTOR rings are 100% CNC-machined from 7075 aluminum alloy so they are both strong and lightweight. The direct mount rings also feature ROTOR’s OCP Mount technology. This allows you to change the position of your oval rings in 1-degree increments so you can find the position that maximizes your pedaling efficiency.
