## Overview

The SHIMANO XT SM-RT86 is a premium 6-bolt brake rotor featuring an innovative aluminum core that efficiently dissipates heat to prevent brake fade. Available in 160mm, 180mm, and 203mm diameters, it weighs just 154g in the 180mm size, offering a perfect blend of lightweight performance and durability for trail, enduro, and cross-country cycling.

## Description

Shimano XT brake rotor, the SM-RT86, stands out from Shimano's lower offerings by its use of an aluminum core to channel heat away from the caliper. This, combined with the ribbed heatsinks in Shimano's XT and XTR brake pads, combats heat-induced brake fading. We value this construction because it results in consistent, reliable braking even on long descents.

## Customer Reviews

### ⭐⭐⭐⭐⭐ The are miles better than the press cut SLX rotor.
*by  on Reviewed in the United Kingdom 31 March 2025*

Much better than the slx rotor. These are cut not pressed so much better than the SLX rotors.

### ⭐⭐⭐⭐⭐ Superb performance
*by  on Reviewed in the United Kingdom 23 July 2025*

Have ice tech rotors on all my mtbs. Perform well and don’t get any fade even after hard use on the trails

### ⭐⭐⭐⭐⭐ Solid rotors
*by  on Reviewed in the United Kingdom 18 May 2020*

Solid rotors that keep cool and don’t warp. Straightforward to install, but if you’re not sure how to set up rotors, there are plenty of YouTube videos to show you. Make sure you tighten using a torque wrench to get even distribution. I use mine with shimano Zee metallic pads, stopping power is immense!
