Made to be used with Shimano Disc Brake to ensure top brake performance and to maintain the safety of your Shimano brake system. Features Ice-Tech cooling technology with aluminium radiator fin. Longer pad-life, good for anti-fade, good constancy either dry/wet. Metal compound. Light weight. Spring included. Technology Ice Technologies The fade, which can occur to disc brake rotor and pad when braking on a long downhill ride for instance, has a negative impact on the braking performance. Shimano has adopted Ice Technologies brake rotor and Ice Technologies pad to realize the cooling technology for consistent performance. The clad disc brake rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminum and stainless steel, provides better radiation performance achieving from 400 ̊C to 300 ̊C surface temperature. Also, the radiation fin has been adopted for the pad. Moreover, the clad disc brake rotor blade and the radiator fin provide long pad life, less noise, less fade and lightweight.
