Shimano Dura-Ace RT-MT900

It uses a multi-layer sandwich structure of stainless steel and aluminum to dissipate heat much faster than standard rotors. This prevents brake fade on long, steep descents, keeping your stopping power consistent when you need it most.

Yes, the RT-MT900 is fully compatible with both metal and resin brake pads. You can choose the pad compound that best suits your riding style and local trail conditions without worrying about rotor compatibility.

Because these use the Center Lock mounting system, you will need a standard external bottom bracket tool or a cassette lockring tool to tighten the lockring. It is a much faster and cleaner installation process than the traditional six-bolt method.

You cannot mount a Center Lock rotor directly onto a six-bolt hub. If you want to switch to these, you would need to either change your hubs or use a Center Lock to six-bolt adapter, though swapping the hub is generally the more reliable solution.

While it carries the Dura-Ace name, which is Shimano's top-tier road group, the RT-MT900 is widely used across both road and mountain bike disciplines. Its heat management capabilities make it an excellent choice for any rider looking for high-performance, reliable braking.
