Shimano XTR RT-MT900

Ice Technologies FREEZA is a specialized cooling system that uses an aluminum core sandwiched between stainless steel layers to dissipate heat rapidly. This prevents brake fade during long, aggressive descents, ensuring your stopping power remains consistent even when the system gets hot.

Yes, the RT-MT900 is compatible with both metal and resin brake pads. This gives you the flexibility to choose the pad compound that best suits your riding style and local trail conditions.

This rotor uses a Center Lock mounting system, which is standard for many modern mountain bike hubs. Please verify that your wheelset is designed for Center Lock rotors before purchasing, as it will not fit hubs designed for 6-bolt rotors.

Yes, it includes an alloy lockring, which is necessary to secure the rotor to your Center Lock hub. You will just need a standard external-notched bottom bracket tool or a cassette lockring tool to tighten it.

The two-piece construction allows for a lighter weight while maintaining high structural rigidity. By using different materials for the braking surface and the spider, Shimano can optimize heat management and durability without adding unnecessary mass.
