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.

Technology:
Ice Tech FREEZA
Shimano Ice Technologies provide a fast heat dissipation at your disc brake. The brake pads are equipped with aluminium cooling fins. The brake rotor is constructed using a sandwich technique in which stainless steel encloses an aluminium core. The stainless steel on both flanks ensures long durability, the aluminium allows heat dissipation. FREEZA is the further development of the brake rotor, in which additional, specially coated ribs in the aluminium of the rotor ensure even better heat compensation. This cooling technology creates consistently high performance and longer brake pad durability while reducing fading and brake noise.
