In Mountain bike riding, trail conditions change drastically from one second to the next, from one turn to the next. Mountain bikers need to be able to seamlessly perceive the conditions, judge their options, and operate their bike in a split second. XTR satisfies the needs of the most demanding riders by providing the highest level of precision and integration. Shimano refocused on the original goal of XTR - to be the ultimate race components.
Shimano's ICE Technology was first developed for superior cooling under the rigors of pro downhill riding, but with a backwards compatible design in many popular sizes, the latest evolution of XTR rotors from Shimano now bring top-of-the-line performance to more applications. The RT-MT900 rotor draws heat away from the brake, which can bog down your stopping power, to deliver consistently superior performance no matter the conditions.
Features & Specs:
- Stronger spider
- Cooling fins for faster cooling
- Backwards compatible design

Best rotors for Shimano disc brake systems!
These are the choice rotors for many pro road cyclist for a reason. Lighter than dura ace, catch less side winds, and plenty of stopping power. The Dura ace versions are also great rotors but if your a little gram concience, and who isnt?.... the XTR rotors are a better choice for road bikes. Biketiresdirect is my favorite online bike parts supplier and VIP program is superb!

Great stopping power!
Got these for a custom build and and I'm happy with these rotors. Could have went with a 180mm rotor as 160mm is a little under powered.

Great Brakes!
I bought the 140mm rotors to put on my road bike, they work great with Ultegra and dissipate heat perfectly. I got them for some marginal weight saving and because they look cool.

Best of form and function
I'm using these on a gravel bike. Stopping power is great and consistent. Aesthetically, they look nice than the other Shimano options.
