Shimano’s RT81 rotors embody their signature Ice-Technology. Ice- Tech produces 25% more braking power. The 3 layer rotor features an aluminum core between stainless steel. This was done to quickly and efficiently dissipate heat. With better head dissipation, there is more consistent braking power.

Been using the Shimano RT64 SLX rotors with SLX brakes for this past summer and braking was fine. The Ice-Techs are true out of the box, great stopping power and better modulation. Highly recommend them if money is not an issue. They work with allmodern Shimano brakes, M615 Deore, M675 SLX, M785 XT, XTR, ZEE.People also installed them with Avid and Hayes brakes.

I replaced a set of non-Icetech rotors after they had worn out. I also changed pads from resin to metal so it would be hard to tell if any braking difference was due to the rotor or pads. Under hard braking the M06 pads with these rotors will howl. I think it's because they get hot. If I'm just bleeding off some speed coming into a turn then the noise isn't bad. The price was good and they work at least as well as the rotors they replaced. There isn't much choice for Centerlock rotors.

    Great product. Easy to install. The only problem I had is my wheels didn't come with the 15mm center lock ring so I had to purchase it separate.

    Comments about Shimano XT RT81 Icetech Centerlock Rotor:

    Bought the 140 mm for rear wheel and it fit my Shimano wheel just fine, however the black arms on the rotor rubbed one of the tabs that extend down from the Avid BB7 caliper. Call the Jenson tech line and they told me to clip off the tab. I did and the rotor now works fine.
    Through trial and error, I found that it's more straight forward to use a rotor designed for center lock wheel that to use an adapter for a 6 hole rotor.

          Comments about Shimano XT RT81 Icetech Centerlock Rotor:

          Smashed my front rotor on a rock and bent it, so I ordered a new one and a Jenson rotor truing tool since I don't have one. For the Centerlock rotors you'll need either a cassette tool or a bottom bracket wrench depending on the wheel. I didn't check this out in advance and had a brief moment of stress, but some quick research let me know I needed the bottom bracket wrench, which I luckily have. Anyway, these are great rotors, and I got the original one trued up as a spare with a little work.

              These discs are very quiet with smooth modulation, especially with XTR brake systems. They have more surface area to relieve heat buildup, but weigh LESS than previous, more expensive, XTR disc versions and they wear evenly and slowly. Have A Good Ride!

                  Theres not much to say about shimano brakes except they rule. To get the benefits of this rotor you need shimano brakes with ice tech pads. When paired these discs are powerful,fade free, and quiet as a mouse in all conditions in any scenario. Gave 4 star cuz i havent tried the RT99 rotors.
