Kool Stop D293A organic disc brake pads. The name Kool-Stop has always been associated with excellent braking and low wear. Thanks to these properties, the pads from Oregon / USA are among the top retrofit brake pads and can even increase the performance of your brakes. The pads are made from organic materials and bonded with synthetic resin. In order to improve the braking properties and reduce abrasion, the lining contains small amounts of metal particles. Even so, the toppings are mostly organic, you could also say they are semi-metallic. This mixture results in optimal dry and wet braking values and also keeps disc wear to a minimum. Aluminum carrier plates are used for type A coverings to further reduce weight, however, these have a higher thermal conductivity, which can lead to premature brake fading in the event of extreme stress, for example on long descents. Thus, these rubbers are more recommended for racing use. Specifications:- Carrier plate: Aluminum- Pad type: Organic- Brake compatibility: Avid Elixir 9/7/3/1 / CR / R DB 5/3/1 SRAM XX / XO
