    XT SM-RT86 Rotor

    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

    Awesome Rotors

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: 180mm

    Couldn't be happier with these -- Shimano makes a great product. Running these now on both my bikes (a hardtail XC and a full suspension). Great linear feel, quiet, and all the stopping power needed. I've been riding on these year-round for about 18 months now and they have worked flawlessly rain or shine. Most all of my riding is on beginner & intermediate single track with steep but short hills, although I did spend a full day last summer doing nothing but harrowing downhill runs at a bike park (fun btw!). That gave the brakes a good issues.

    they stop my bike nice

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    I have a 203 up front and 180 in back paired with a set of M9120 brakes and I have no complaints.

    Don't buy

    • Familiarity: I've put it through the wringer
    • Fit: Runs large
    • Size Bought: 160mm

    Ice tech rotors are designed for the most recent M8000 series Shimano brakes and don't work with earlier makes and models by design; the inner aluminum spider is too large and hits the brake pads or calipers. Adjusting the calipers to keep these beautiful puppies, only eliminates the braking surface. While they in fact dissipate heat on a long down hill, they are softer, more easily damaged or bent, they take little abuse and do not brake better than 12 dollar stainless steel rotors with good pads. I purchased 3 pairs for the GDMBR and refuse to ride them. Jenson and REI refuse to publish negative reviews to protect a sales magnet. Buy them only to ware as a sign of your gullibility, keep them only as a sign of your vanity.

    160mm lol

    Great rotor

    • Familiarity: I've put it through the wringer

    Good, hard-working rotor. Dissipates heat pretty well which will help slow the fade on the long descents. I have had mine a couple of seasons and don't see any signs that I will need to replace them any time soon.

    Will pair well with XT BR-M8120 and XT BR-M8100

    Work great

      These rotors cool fast so you don't lose braking power on long downhills. I have them on all my bikes. They last a long time and work well with the ice pad. They stay quiet too.

      Work great

      for the 203 needs better shipping

        I got the 180mm and it was perfect. The 203 needs to be taken to a mechanic to have it fixed.

        Cool rotors

        • Familiarity: I've used it several times

        I got the Ice tech rotors to replace my stock SRAM rotors that were always over heating, I'm impressed with their ability to stay cool on long descents, so far no issues at all, I love them!

        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.....

          same here, the 180 was fine but the 203 needs work

          Love 'em

            Love shimano rotors.

            Brake Time

            • 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.


              • 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.
