Description
Top Of The Line — Road Or Mountain
Designed to keep your braking system cool on long, demanding descents, the XTR/Dura-Ace RT-MT900 Centerlock Disc Rotor rapidly dissipates heat for more consistent braking performance in extreme conditions, as well as longer pad life and reduced brake fade. These rotors are optimized for the XTR M9100 and M9120 brakes as well as the new Dura Ace, and feature a new design that improves cooling and decreases weight compared to the previous version of the XTR rotor, the RT-99.
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 have now been incorporated into their Dura-Ace road groupset. 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:
XTR/Dura Ace rotor offering improved cooling and braking performance
3-layer Freeza construction dissipates heat on long descents
Enjoy consistent performance, longer pad life, reduced brake fade
Surface temp cooled by up to 20-degrees Celsius vs. RT-99 rotors
140mm and 160mm rotors shave grams for road, gravel and XC
180m and 203mm are designed for aggressive trail and enduro
Shimano Centerlock attachment with lock ring included

They do a good job of stopping the bike and are easy to install.
These rotors are great. Can't say that they're necessarily better than any others, but they do a good job for a good price.

Great feedback feeling
Love the feeling of the brakes holding on descents and not fading. Big difference from my road Ultegra rotors!

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.

Shimano XTR Rotors AKA Dura Ace 9200 Rotors
After catching wind of world tour riders using these on the road I ordered a set to see how they felt compared to the regular Dura Ace / Ultegra rotors, suffice to say its why this is the new road rotor for the 9200 group.

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.
