  • The RT-MT800 brake rotor by Shimano stands for perfect heat dissipation.

    The Shimano RT-MT800 brake rotor with internal serration uses Ice Technologies FREEZA heat dissipation to further reduce temperatures, 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.
