Kool-Stop XO/Elixir/Guide Disc Brake Pads

Kool-Stop disc pads are made with organic materials that are blended and bound together using a resin. The compounds do include small amounts of metal to improve the braking formula but though this is a mined material the pads are largely organic. The term semi-metallic can also be used. We have found during testing that our disc pads are Rotor Friendly and provide high performance braking throughout the life of the pad.
