Shimano XT SM-RT86 6 Bolt Ice-Tech Rotor

With riding styles growing more aggressive and varied, a better brake rotor was needed. Shimano responded to the needs of riders to deliver best-in-class braking power, better system cooling and the best brake feel. Enter the Ice-Tech Rotor. The Shimano XT RT86 rotor is infused with proven Ice-Tech braking technology, trickled down from the top-end XTR group. Ice-Tech is a technology that blends the durability of a stopping power of a steel rotor with the heat dissipation properties of aluminum. By sandwiching an Aluminum cooling core between two steel braking surfaces, the rotor dissipates heat faster, while the steel outer portion provides solid stopping power and a durable braking surface. The two-piece "floating" rotor arrangement also saves weight and increases system stiffness, giving you the intense braking power you need, with the reliability and survivability that Shimano is best known for. Hit every line with confidence and speed with Shimano XT Rotors!

Features

  • Ice-Tech Technology provides maximum cooling
  • Two-piece floating rotor design aluminum core and steel braking surface provides the best in weight, cooling efficiency and performance
  • 6-Bolt disc brake mounting fits 6 bolt hubs.
  • T25 Torx mounting bolts included 15g
  • Adaptors not included
  • Compatible with most disc brakes but for maximum performance it is strongly recommended to use with Shimano disc brake calipers and brake pads

Good stuff!
My new bike some upgrades. I had already used them before on my other bike and they have a very good braking power. Considering price and quality, it is a good purchase.??????

How Cool? Ice Cold!
I often do long descends and the ice tech Rotors have been the only ones that don't over heat. I'd recommend giving them a try. ????

Stop using used ones. Buy new ones!
I had to stop using used rotors on my new builds. Once I bought these, HUGE difference in braking power.

BUYWER BEWARE - Received rotor differs from rotor shown in product image. Made in China, poorer build quality.
The product description image clearly shows that these rotors are supposed to be made in Japan and have a brushed surface finish and laser-cut edges, but the product I received appears to be stamped, have a glossy surface finish, and is made in China. Build quality is significantly lower than the Japanese-made variant.

Great stopping power, looks great too.
I bought this to complete my build on a yeti SB-66. This rotor is huge, and has plenty of stopping power. I have XT brakes, and this worked great with them. I haven't experienced any fade at all, even during heavy, repeated braking. Shimano engineered the ice-tech rotors with an aluminum core which will dissipate heat better.

Not flat
For the price I would expect better, both rotors I purchased had a high spot / slight warp new in box! very disappointed, but it will wear in, hopefully!

Awesome rotor.
Doesn't get much better than Shimano's Ice Tech stuff. Technology meets attractive and lightweight design. Would work great in any brake system where applicable. I bought the 203 version for my Yeti SB66. Powerful stopping and no fade even on long descents.

Well worth the $$
Upgraded my entire braking system from Avid to the XT. All the reviews are correct and could not be happier with making the switch! Easy to install, so responsive, and most of all it doesn't scream like a dying cat as I descend.

PROS: Attractive Design, Durable, Easy To Install, Lightweight, It's Quiet

These rotors keep cool under the highest braking conditions. Never once Have I noticed any sort of brake fade. I love that it is a two piece rotor!

PROS: Attractive Design, Lightweight, Easy To Install, Keeps Brakes Cool

Great rotors, easy to install
Great rotor, very easy to install. One word of note: instructions are outdated and reference a washer and triangle screws. The screws are no longer triangle, and Shimano no longer uses a washer for these rotors. Just tighten the screws and lift the flaps. I found it a little easier to lift up the tabs first, then tighten everything - otherwise it's impossible to pry the ends even with a tiny flat screwdriver.

PROS: Easy to Use, Durable, Lightweight

Quiet rotors
My bike came with low end rotors and shimano calipers. They would make a lot of noise. I tried cleaning the pads but it didn't help. I put these on and the brakes seem so much more powerful and dead quiet!

Upgraded from SLX
I ordered this as part of a 1x11 drive train upgrade I did on my Giant Anthem. I had previously ordered the new XT M8000 brakes for the upgrade, but planned not to replace the rotors as it seemed like a waste considering the rotor were not that old, but after getting the new brakes on the bike I thought maybe I should. After getting them installed, I was glad I did. The new setup with the M8000 brakes and these rotors stops on a dime. Issues I previously had with heat build up on long descents with my old SLX brakes are now no existent. Worth every penny.

PROS: Durable, Easy to Use, Lightweight

Brakes The Way They Should Be
Been using the Avid G2 Cleansweep rotors with XT M785 brakes for this past summer and the rear brake was never quiet. Stopping power was there but it was a bit of an on/off with metallic pads. Finally got to replace the rotors with the Ice-Techs and my problems are gone. True out of the box, great stopping power and better modulation.

PROS: Lightweight, Easy To Install, Attractive Design

CONS: Expensive

BEST USES: Mountain Biking, Racing
