Shimano 160mm CL XT RT-MT800 Ice-Tech Freeza

Shimano - SM-MT800 Centerlock 160mm brake disc

The SHIMANO ULTEGRA SM-MT800 brake discs provide constantly high braking power in all conditions thanks to the ICE TECHNOLOGIES FREEZA construction. With their improved heat management, the SM-MT800 brake discs decisively reduce brake fade on long downhill rides and significantly reduce noise during braking. SHIMANO's CENTERLOCK mounting system with toothed profile and lock washer significantly facilitates the installation and removal of brake discs. The combination of a steel rotor and an aluminium adapter reduces the weight. The SM-MT800 disc is compatible with both organic resin pads and metallic sintered pads. The holes in the disc reduce the contact area and the air baffles improve the cooling properties of the disc.

ICE-Tec Freeza

Ice Technologies, in combination with the Freeza brake disc design, ensures rapid heat dissipation. This results in more consistent braking performance under extreme conditions, extends pad life and reduces brake force loss and brake noise.

Advantages and features

The lightweight brake discs with heat dissipating painted protruding aluminium layer segments deliver excellent cooling performance, consistent braking power and easier handling in all conditions.
The brake discs with aluminium/stainless steel cooling fins dissipate heat quickly. This reduces maintenance requirements, extends brake pad life and reduces brake power loss and brake noise.
The lightweight, highly efficient three-layer sandwich structure (one aluminium layer between two stainless steel layers) promotes heat dissipation.

140 °c heat reduction (compared to stainless steel brake discs).
