    Stays cooler so you stay in control.

    Shimano’s XT Brake Rotor, the SM-RT86, sets itself apart from Shimano’s lower-tier offerings through its use of an aluminum core to transfer heat away from the brake caliper. This, combined with the finned heat sinks in Shimano’s XT and XTR-level brake pads, combats heat-related brake fade. What that means in trail terms is consistent, reliable braking, even on long, technical descents.

    • Aluminum core sandwiched between steel faceplates conducts heat away from the brake
    • 160, 180, and 203mm options
    • Six-bolt mounting
    • Item #SHI001B

    Awesome rotor!

      I've had these on my past couple of race bikes, and I've always been happy with them. ICEtech is the real deal, I've never had problems when overheating. On top of it all, they look great! Defiantly the way to go unless you're going XTR.

      Shimano Gold Standard

      • Familiarity:I've put it through the wringer

      Go to rotor for shimano setups w/ 6 bolt compatible wheels. Well engineered and manufactured, incredible temperature control and impressive durability. Really the gold standard for rotors!

      Shimano Concept and Quality in a rotor

        I have tried many rotors. Purchased this one to give it a shot since I have seen it on so many bikes and good price.

        Came to me a bit warped, and I wasn't gonna deal w return because that was gonna stop me from riding my brand new bike.

        Functions great reduces heat. Is not a true floating rotor but it is debateable if that is even better. I liked my hope floating rotors but they are heavier, but they also have a thicker aluminum and metal rotor but more expensive and heavier.

        Stopping Power

        • Familiarity:I've put it through the wringer

        Upgraded to shimano brakes on a bike, went 180 front and rear. No squeals, no chatter, just stopping power. 180 rotors require adapters, but they are cheap and easy to figure out, and you can find them here
        Buy these, install them, and go shred. Simple.
        Every bike I own from here on will have Shimano brakes and rotors.

        Go big or go into the bushes

        • Familiarity:I've put it through the wringer

        Go 180 rotors front and rear. Even on XC bikes. Negligible added weight with significant gain in control. If you have Shimano brakes use these, nothing else. They are totally quiet, unlike a SRAM rotor I tried using that was a total disaster (like all SRAM brake items).

        The Rotor!

        • Familiarity:I've put it through the wringer

        Great all around rotor. Shimano has always made great durable rotors. Ice tech is a technology that shimano has applied to their higher end rotors. Ice tech is a 3 ply rotor, 2 steel outer pieces with an aluminum inner piece pressed in between. This help too keep the rotor cool and stop overheating.

        Worthy upgrade

        • Familiarity:I've put it through the wringer

        I recently replaced the Shimano Deore rotors on my Santa Cruz Bronson with the ice tech rotors and I'm pretty happy with the upgrade. My rotors were due for a replacement so I decided to bite the bullet and go with these. My bike came stocked with the Shimano Deore M615 brake set and these rotors work just fine. I have noticed slightly better performance on long downhills vs. the non-Ice Tech rotors that were stocked on the bike. They tend to fade less and keep more consistent, especially near the end of the descent. I wouldn't say that it's such a night and day difference that you should scrap your non-Ice Tech rotors if they're in good shape, but when it comes time to replace worn out rotors, these give a pretty decent performance boost.

        Ice Tech is IN

        • Familiarity:I've put it through the wringer

        I wouldn't use any other rotor with my XT brakes. The heat reduction design of the calipers, brake pads, and these rotors makes the brakes work better, longer. Without a doubt, the best combination in braking.

        Who says size doesn't matter!?

        • Familiarity:I've put it through the wringer

        I mounted this on my Diamondback Mission 27.5. I felt the 180's that came on it were inadequate, so I upgraded the front to this 203. The difference was noticeable. The bike now stops like a nimble 26" bike. My rotor arrived not perfectly true, but once I sorted this out, it has stayed true after the bed-in process, is quiet, is effective, and looks badass! The extra stopping power of the rotor comes from the size, not so much the material. The material more pertains to the weight and heat dissipation properties. Enjoy!

        Stopping power!

        • Familiarity:I've used it several times

        These do what they are designed to do. Compared to the lower end rotors I had on my bike these provide much better stopping power. I also saved some weight swapping to them.

        Great with XTR Brakes

        • Familiarity:I've put it through the wringer

        I picked up a 203mm for the front of my Nomad and 180mm in the rear. They slow me down just fine!

        building a santa cruz bronson now, going with the XT breaks and wondering what size rotors i should get? little feed back. I also do mostly trail riding / all mouton. will this break set up be a good choice?

        Has anyone ever used these on avid bb7 mechanical road breaks? If so how are they?

        I just installed a pair of these 203 mm rotors on my tandem equipped with Avid BB mechanical calipers and immediately saw that the inside brake pad tabs were getting in the way. No problem: I just shortened these tabs just enough to leave a clearance of about 2 mm. Improved heat dissipation is important with tandems because of the enormous weight factor (from 300 to 500 pounds!)
