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.
Compatible with Red, Force, Rival, and Apex HRD, Level TLM, Level Ultimate, and Red AXS Mono-Bloc calipers
