Galfer's Gold HH Sintered compound is formulated on advanced Ceramic composites.Galfer wanted to push the envelope with this new compound. The advanced ceramics allow the brake pads to self cool and dissipate their own heat once the rider releases the brake lever. Pads without this type of compound tend to retain heat and “fade” under hard or repeated braking. The sintered compound is also easier on the rotors compared to most other sintered metallic compound brake pads. *Galfer Gold HH Sintered Brake pads have a white ceramic coating on the backing of the pad.
