Description

Functionally, XT SM-RT86 Disc Brake Rotors stop equally in comparison to Shimano's apex XTR line. That's because of Ice Tech, a shared technology on both models. The difference between the two lies in a slightly lighter XTR spider that's reserved for gram-obsessed racers.

In reality, most of us aren’t going to feel the benefits of a few grams lost when they're so centrally located to the hub. However, what we are going to profit from is the three-piece Ice Tech Rotor. It is essentially two pieces of steel optimized for friction sandwiched over an aluminum core.

This means Shimano is utilizing the high thermal conductivity of aluminum, where other manufacturers solely use steel throughout the braking surface. Additionally, the quicker cooling alloy core more efficiently transfers heat to the alloy spider. The resulting cooler operating brakes will last longer and provide more consistent stopping in the most trying conditions.

Additionally these rotors are compatible with SLX and Deore calipers if you'd like to upgrade existing brakes. Shimano's XT Ice Tech 6-Bolt Disc Brake Rotor SM-RT86 are available in three sizes -- 160, 180, and 203mm.

  • Aluminum core sandwiched between steel faceplates conducts heat away from the brake
  • 160, 180, and 203mm options
  • Six-bolt mounting

Silent Stoppers

  • Familiarity: I've put it through the wringer



Unless you get water on them these things are silent. Ive ridden them in every condition and could not be happier with them.

Great Rotor

  • Familiarity: I've put it through the wringer

I've been using XT rotors for the past two seasons with XT Brakes. Bang for the buck it's the best Brake System I've used. They work great and are extremely reliable. Highly recommended.

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.

Love em

  • Familiarity: I've put it through the wringer

I have used these for years and they do their job. As long as you keep usable pads in your brakes the rotors will work for a long long time.

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.

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.

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.

Great Rotor

    One of the easiest upgrades for your bike. Quit over heating and use ice tech rotors.

    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!
