Shimano RT-MT905 XTR 6-Bolt 180mm Road Disc Rotor

With the Ice-Tech cooling technology, the RT-MT900 brake disc ensures constant braking performance even on longer descents. The brake disc is characterised by a three-layer sandwich construction.

The stainless steel flanks with an aluminium core offer significantly improved heat dissipation. This allows the temperature to be reduced by around 100 C.

In addition, the Freeza aluminium cooling fins reduce the system temperature by around a further 50 C thanks to their increased surface area. Due to the higher heat dissipation, smaller brake discs than usual can be installed. In addition, the service life of the brake pad is significantly extended.
