Shimano's RT-MT800 brake rotor stands for great heat dissipation

The Shimano RT-MT800 brake rotor with External Serration reduces temperatures even further through the Ice Technologies FREEZA heat dissipation, resulting in more consistent braking performance. The life of the brake pads is also extended. The RT-MT800's proven sandwich construction with an aluminium core between two layers of stainless steel ensures efficient heat dissipation via the integrated radiation fins.

Ice Tech FREEZA brake rotors show even less fading due to 40° C less heat development compared to SM-RT98. The three-layer sandwich construction consists of stainless steel flanks and an aluminium core with integrated cooling fins. The two-part structure with the aluminium spider dissipates the heat well. The dirt-repellent design extends the service life of the rotor and pads. A real eye-catcher is the sporty, aggressive high-tech design.
