The Wave brake rotor design was invented by Galfer in the early 90s as a solution to water and mud on brake rotor surfaces of trial competition motorcycles. As Galfer developed the design, they discovered the brake system was running cooler. When Galfer combined a new design with the premium materials they had already developed for their round rotors, the resulting breakthrough began the new generation of brake rotor technology.
