The RWD Light rotors have been designed specifically to address some of the issues associated with light weight disc rotors, pulsating and poor lateral stiffness, and by solving these issues make them ideal for both MTB and road bike applications.

One major issue with light-weight disks, with large cut-outs on the braking surface is the pulsating vibrations that get transmitted from the brake pads through the forks and back to the brake lever. This latests generation of braking ring eliminates this issue.
