    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

    Great Rotors

    • Familiarity: I've used it several times

    I bought these rotors to replace the front rotors on me trike. I am 230 lb and the trike is about 45 lb. On a down hill run over 20 MPH It takes a lot of braking power. These the rotors get the job done with out a problem.

    Outstanding!!!!

      These rotors are outstanding. I put these on my 2017 Giant Trance 2 and they work great. Incredible stopping power. I have not felt any brake fade with these rotors. You can not beat the price of them either. You can buy two of them from Back country for the price of one at a local bike shop. Very pleased with my purchase.

      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.

        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!)
