Galfer Wave(R) Disc Brake Rotor Diligently made in Spain, the Wave(R) Disc Rotor is Galfer's research and development at its' best. Each rotor is laser cut and double-disc ground from high carbon stainless steel for powerful, progressive and modular braking in both dry and wet conditions. An anti-corrosion treatment is applied to the high carbon stainless steel to increase longevity. The Wave's high temperature resistance properties ensure stopping performance when repetitive braking is required. Galfer offers the Wave(R) in different rotor sizes depending on the discipline from Cross-Country, Enduro, Downhill to Cyclocross.
