    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

    Unanswered Question

    Will the XT SM-RT86 rotors work with XTR BR-M9000 brake calipers? What are the best 6 bolt rotors to use with the XTR BR-M9000 brake calipers? What size rotors should I use for XC riding? I'm leaning towards 160mm. I'm not sure if this info will be helpful in answering my questions, but my bike is a Pinarello Dogma XC with Mavic Crossmax Pro Carbon rims, and my weight is around 200lbs while dressed for riding. Thank you for helping me with these questions.

    arrived bent

      Box was in great shape, no sign of damage, but the rotor was bent enough that it wasnt useable until I spent 2 hours bending it back into shape, which I couldve just done with the original.....

      Love 'em

        Love shimano rotors.

        • Familiarity: I've used it several times

        Grate rotors!

        Awesome rotors, great value

          You will have all the confidence you need going downhill.

          Awesome Rotors - Great Deal

          • Familiarity: I've put it through the wringer

          Great rotors for the price. Fairly light weight, shed heat well and I think look pretty good too.

          Perfect.

          • Familiarity: I've put it through the wringer

          Shimano is killing the stop game. Can't be beat!

          icey baby

            ice tech rotors keep my setup dialed. have been great paired with my zee brakes. running 204 front 180 rear

            icey baby

            Sweet Rotors!

            • Familiarity: I've used it once or twice and have initial impressions

            I bought these as an upgrade to my Shimano Deore M615 brakes. They run cool and quite with the IceTech finned pads. They look great too! Highly recommend.

            Sweet Rotors!

            ice ice baby!!!!

            • Familiarity: I've put it through the wringer

            stopping power and then some!!!!!

            nothing but ice!!

            • Familiarity: I've put it through the wringer

            203mm on everything, wanna stop?

            Quiet and easy

              The iceshield on these rotors keeps them very quiet even after hours of use on downhill runs. Easy to install.

              Great Rotor

                These rotors paired with Shimano brakes are outstanding. If you want increased braking power, especially on longer descents, get these! Also- getting a larger rotor will help with increased braking power, just make sure you have the proper adapter for your bike if you’re increasing the size of the rotor. I would be hesitant to mix and match rotors and brake calipers of different brands (Shimano/SRAM/Magura) because of different rotor thicknesses…I would definitely recommend if you currently have lower end Shimano rotors or are just looking to replace your XT rotors.

                Go to rotor

                • Familiarity: I've put it through the wringer

                These are the only rotors I'll run on the mountain bike! Feel free to shoot me an email at jdraper@backcountry.com if you don't know which size is going to work best for you!

                New rotors are the best!

                • Familiarity: I've put it through the wringer

                Having new rotors AND new brake pads is like having new brakes.
                Love it!

                super reliable

                • Familiarity: I've put it through the wringer

                For the money the XT rotors can't be beat. great longevity, great braking power, have not had any heating issues. Highly recommended.

                Reliable Quality

                • Familiarity: I've put it through the wringer

                I usually use SLX rotors but these work great too for not much more money. Are they lighter, faster, better? Probably, I don't know, the difference isn't too noticeable for me personally but if you are heating up your brakes frequently, these should dissipate that heat better.

                Stopping Power

                • Familiarity: I've put it through the wringer

                If your using 6 bolt hubs these are the shimano rotors of choice.

                The Best!!!!

                • Familiarity: I've put it through the wringer

                If you are using Shimano brakes, you better use their rotors! They work the best.

                Buy Shimano

                • Familiarity: I've put it through the wringer

                If you want your bike to stop...buy these. EASY to maintain too....
