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

Best Rotors

  • Familiarity: I've put it through the wringer

Shimano IceTech are the best rotors on the market, especially if you are running Shimano brakes. the heat dispersing tech behind them ensure that your brakes run as needed throughout your ride even after long descents.

Great price for a great rotor.

  • Familiarity: I've put it through the wringer

Running these on two bikes right now. My hope rotors were much lighter but developed a shift no matter how tight I made the bolts. So I put these on because I remembered their mounting bolts and clips. No problems so far. Just work.

great rotors

  • Familiarity: I've put it through the wringer

No the ice tech rotors but a little cheaper, I am not a EWS pro racer or anything so I went with these because I have ran Ice Tech rotors and couldnt tell the difference. These are solid and of course shimano quality.

Are you sure they aren't Ice Tech? It looks like it says it on the rotor in the product pic.

Soo Icey!

  • Familiarity: I've put it through the wringer

Shimano knows brakes, whether is calipers or rotors - they put out a great product. I've run XT for many years and in my opinion you cant beat it for the price. Their SLX is also a tremendous option. Simple, hassle free and perform at a top notch level!

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.
