Kool-Stop disc pads are made from organic materials that are blended and bound together using a resin. The compound does include small amounts of copper which improves the braking formula.

Our E-Bike disc pads are produced with a ceramic barrier between the organic friction material and the steel backing plate to reduce heat transfer into the brake calliper causing brake fade. With the heavier design and higher speed of Electric bikes, they require a compound that will hold up and provide consistent braking power.
