    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.

    • A workhorse brake rotor for XC, trail, and all-mountain use
    • IceTech steel/aluminum sandwich dissipates heat
    • Aluminum spider further contributes to heat management
    • Item #SHI001B

    Braking Power

    • Familiarity: I've put it through the wringer

    Love these rotors! They last a long time and work great! Finally had to buy a replacement for my older 2014 bike, so 3 years of abuse seems pretty decent for someone who probably uses her brakes too much! Good price for the quality as well!

    Why are there other rotors?

    • Familiarity: I've put it through the wringer

    This rotor is great. Maybe not quite as fancy as XTR, but also a good bit cheaper. And the heat dissipation is still pretty dang good. I've used a ton of these on my different bikes over the years

    Pretty excited

      I bought these to put on a new build for a Yeti SB6 and am excited for the upgrade from the build of my old SC Bronson. It is the middle of winter here in Park City so it will be a while before I get to reap the benefits of the upgraded build on a new bike, but im excited to get out there soon!

      IceTech IS Worth it!

      • Familiarity: I've put it through the wringer

      Hard to beat Shimano brakes on the MTB. Was having problems with the non-IceTech rotors on some of the long descents in Pisgah loosing stopping power and feeling mushy. Simply changing to IceTech rotors fixed my issues instantly. Can't beat that!

      Stay calm by staying cool

      • Familiarity: I've put it through the wringer

      Want your brakes to work even when you're over working them? Get these. The Ice tech rotors cool faster for better continuous performance. Want more power? Get the larger rotors. I've been running these on different bikes for many years and still can't find a complaint.

      Great Rotors

      • Familiarity: I've put it through the wringer

      I've got these rotors on my mountain bike to accompany my Shimano XT brake systems. The stopping power is awesome and they have held their shape after a few good crashes. They're durable and hard to beat!

      Major Upgrade in Stopping Power

        I use these rotors in all things mountain biking, and this time around, I decided to install them on my cross bike... LIKE WHOA!

        Stopping power is up 10 fold this season, and I am kicking myself for not switching to them sooner.

        This is a cheap and simple upgrade, get them NOW!


        Easy DIY

          Get yourself a digital caliper and check width every time you check your chain wear. Shimano prints on disc the min width at 1.5mm.

          Handheld drill + torque wrench make for quick change. Don't forget the loctite. I usually give the hubs a good cleaning before installing new. Check pad wear too!

          Great rotor!

            I bought these to replace the worn out and bent factory Formula rotors my bike came with stock. I've got these rotors paired with EBC's green formula pads and I noticed a huge difference in stopping power over my old rotors the first lever pull! I assume they stay cool enough, I've never bothered to bail off the bike and touch the rotor or bad to see how warm they really are after a long descent, but I've never had brake fade issues with these rotors.

            Great rotor!

            So Icy

            • Familiarity: I've put it through the wringer

            If you're running Shimano brakes and your hubs have a 6-bolt mount, these rotors are the best that Shimano has to offer. Light, sweet looking, and they seem to stay cool enough. Sure the XTR-level rotors get the fancy radiator fins, but then again, most of us probably aren't willing to buy Centerlock hubs for the negligible cooling benefits.

            Still the standard!

            • Familiarity: I've put it through the wringer

            Great performance, priced right and very durable. I tend to be hard on brakes and the XT rotors seem to be able to take more punishment than most. Jonathan gives a great piece of advice in the review below; pay attention to the torque specs! Also, stagger tightening the bolts in a "star" pattern and work up to the torque spec.
            More info here: http://www.shimano.com/media/techdocs/content/cycle/SI/DiskBrakeSystem
            If you need a torque wrench, check out the Park Tool Ratcheting Torque wrench (Accessories /Tools & Maintenance /Tools Tools for the Shop/ Wrenches). Definitely a worth-while investment!

            Like most of the reviewers, I've seen the light and switched across to Shimano and Ice Tec (on my dually).

            My question is, as I'm running Avid XX brakes on my hard tail, does anyone know if the Shimano XT rotor will (or can be made to) fit Avid XX calipers?

            Appreciate any assistance (preferably beyond the "just ditch your Avids" response!) 😀

            Not sure about the specific body shape on the XX, but I had to file down a small bit of one of the pad retaining bumps on my Avid Elixir R to clear the spider of the 160mm XT rotor. It's a very minor modification (see attached). These rotors with Koolstop porcupads (front) or Jagwire Pro (rear) have at least as good if not better power/feel as the full-XT setup I tried. Seem long-wearing and have been squeal-free, too... Honestly, I've had no issues at all with my Elixirs in 5 years of riding. Tried a few Avid rotors, Ashima (light, scary light), and these XTs... While they add some weight they seem to shrug off the hairy fast 30%-grade-with-90º-bends-at-oak-trees descents over and over again.

            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!)
