Shimano XTR MT900S Disc Brake Rotor Center

With the Ice-Tech cooling technology, the RT-MT900 brake disc ensures constant braking performance even on longer descents. The brake disc is characterized by a three-layer sandwich construction. The stainless steel flanks with an aluminum core offer significantly improved heat dissipation. This allows the temperature to be reduced by around 100 ° C.
In addition, the FREEZA aluminum cooling fins reduce the system temperature by approx. Another 50 ° C due to their enlarged surface. Due to the higher heat dissipation, smaller brake discs can be installed than usual. In addition, the service life of the brake lining is significantly extended.
As is typical for Shimano, the discs are suitable for the center lock mount , which enables quick and easy assembly, offers a secure hold and ensures a clean and compact look. A lighter aluminum carrier saves a few grams of weight compared to the previous version.
