    Details

    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

    Gettin' Stopped

    • Familiarity:I've put it through the wringer

    If you've been riding the same rotors for sometime now, and their stopping power is getting weak, it's prolly time for some new ones.

    The Ice-Tech is where it's at with these guys. If you need to stop hella quick, it's gonna happen with the rt86's. Easy to install, so you can get back out and get rippin'

    Great rotors

    • Familiarity:I've put it through the wringer

    These work really well. The stop on a dime making it easy to take more speed into the beginning of a turn and scrub speed exactly when needs. Throw a counter steer and proper foot placement into the mix and you get flow-tasticness.

    No vent fans

    • Familiarity:I've used it several times

    My bike's original wheels came with vented ice tech rotors that Shimano supplies standard on my trek domane.
    These cannot be fitted on this and I'm also not sure if these are 'real' ice tech rotors as yet don't have thre same compound.
    Regardless, these are great brakes regardless and will work with any application you desire.

    Benchmark

    • Familiarity:I've put it through the wringer

    Shimano hit a homerun with their latest brakesets. The rotors run quite and low temp even under extreme braking. I have found that the rotors last well past a season and do not need replacement too often.

    Perfect Rotor

    • Familiarity:I've put it through the wringer

    Easy installation and fantastic stopping power make these a pretty no-brainer purchase.

    Obviously the rotor is only one half of the braking equation, but if you stay on top of your maintenance and make sure your brake pads are in good shape you will get plenty of use out of these rotors.

    Best Rotors you can buy

    • Familiarity:I've put it through the wringer

    I made the switch over to XT rotors last year and will never turn back. Great consistent braking. Rotors stay true. I've only had one situation were I didn't feel like the brake rotors were adequate (6mi descent in American Fork Canyon 8-10% grade). This could have been remedied with a larger rotor size.

    Awesome upgrade from SLX, on 3 bikes

    • Familiarity:I've put it through the wringer

    I've upgraded the front rotor on three bikes to this. Two 180mm and one 203mm. One XC bike, one trial bike, and one enduro bike. The extra material in the center feels like it eliminates some flex when jamming hard on the front brake at low speeds. Love it. Comes with two features to prevent screws from backing out - washer plate and thread locker. Seems like it reduces some noise under extremely hot braking conditions, but I also upgraded to ice tech pads, so it's tough to say for sure.

    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.

        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!)
