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

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.

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

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.
