Description

Functionally, XT SM-RT86 Disc Brake Rotors stop equally in comparison to Shimano's apex XTR line. That's because of Ice Tech, a shared technology on both models. The difference between the two lies in a slightly lighter XTR spider that's reserved for gram-obsessed racers.

In reality, most of us aren’t going to feel the benefits of a few grams lost when they're so centrally located to the hub. However, what we are going to profit from is the three-piece Ice Tech Rotor. It is essentially two pieces of steel optimized for friction sandwiched over an aluminum core.

This means Shimano is utilizing the high thermal conductivity of aluminum, where other manufacturers solely use steel throughout the braking surface. Additionally, the quicker cooling alloy core more efficiently transfers heat to the alloy spider. The resulting cooler operating brakes will last longer and provide more consistent stopping in the most trying conditions.

Additionally these rotors are compatible with SLX and Deore calipers if you'd like to upgrade existing brakes. Shimano's XT Ice Tech 6-Bolt Disc Brake Rotor SM-RT86 are available in three sizes -- 160, 180, and 203mm.

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

Great Rotor

    One of the easiest upgrades for your bike. Quit over heating and use ice tech rotors.

    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!

      Amazing temp control

      • Familiarity:I've put it through the wringer

      I purchased a 180mm and 160mm rotors, they offered great braking performance with minimal fade. Aesthetics are a plus too.

      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.

        Awesome rotors!

        • Familiarity:I've put it through the wringer

        The IceTech rotors are great. Definitely a noticeable difference over the old rotors.

        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
        www.competitivecyclist.com/shimano-disc-brake-adaptors
        Buy these, install them, and go shred. Simple.
        Every bike I own from here on will have Shimano brakes and rotors.

        Light, easy to install, nice rotor!

        • Familiarity:I've put it through the wringer

        Wow these rotors are nice. If in doubt about size, as others have said, go big - the weight penalty is minimal with these 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).

        do i need to get adapters? for 180

        bought to buy fork today trying to get the fox 36 if not then the pike

        Yes, you will need the adaptors to use 180 rotors. They vary depending on your frame, but you'll likely find what you need right here- http://www.competitivecyclist.com/shimano-sm-ma90-disc-brake-adaptor

        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?

        Hi Aet,



        I'd go 180 front and 160 rear. Contact me directly and I can help you with your custom build.

        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.

        solid rotors

        • Familiarity:I've put it through the wringer

        simplicity and low maintenance are nice things to have on your mountain bike and these are that. just install and you won't have to think of them again.

        Silent Rotors

        • Familiarity:I've put it through the wringer

        Unless you get water on them these things are silent. Ive ridden them in every condition and could not be happier with them.

        Super great

        • Familiarity:I've put it through the wringer

        These are amazing, keeps the brakes nice and cool! They noticeably help with brake fade. But it is beneficial using them with xt brakes to help close off the system!

        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.
