Shimano's Ice Technologies ensures a high level of braking ability maintained. Heat friction can increase temperatures of rotors, callipers and pads. Controlling this heat not only reduces fade, but increases pad life and reduces noise. Brake discs heat up during braking and this needs to be dissipated. The pads possess fins leading to effective heat dissipation. The pad's back plate has a 2 layer structure, consisting of an aluminium plate and steel behind. This means heat is less easily transmitted to calliper, increasing brake life and reducing noise.
