Shimano: Saint / Zee / XT & XTR4 With our AirCon Brakepad System you will be able to install cooling fins to your brake. The fins are not attached to the pad, so that you can reuse the fins and produce less waste. Apart from the cool look it will reduce the heat in your brake caliper up to 9%.

Another benefit is that you just need to buy the AirCon System once and can replace the pads with our AirCon Replacement Pads separately.
