Shimano XTR RT-MT900 Disc Rotor

Ice Tech FREEZA is designed to manage heat buildup during long, aggressive descents. By using specialized cooling fins, it dissipates thermal energy faster than standard rotors, which helps prevent brake fade and keeps your stopping power consistent.

Yes, the RT-MT900 is engineered to work 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.

Yes, you will need a cassette lockring tool to tighten the Center Lock ring. This system is generally faster and more secure than the traditional six-bolt mounting method, but it does require that specific tool for installation.

While the rotor itself is high-performance, you must ensure your bike frame and fork are rated to accept a 203mm rotor. Check your manufacturer's specifications for maximum rotor size compatibility before upgrading to avoid potential damage.

The hybrid construction balances durability and thermal management. The stainless steel braking surface provides the necessary friction and wear resistance, while the aluminum core and cooling fins act as a heat sink to draw temperature away from the braking track.
