## Overview

The Shimano XT SM-RT86 is a premium 6-bolt brake rotor featuring an aluminum core for superior heat management, available in 160mm, 180mm, and 203mm diameters. Weighing just 154g in the 180mm size, it delivers reliable, fade-resistant braking performance ideal for trail, enduro, and cross-country cycling. Highly rated by riders for durability and consistent stopping power.

## 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.

Review: Quality brand product - Amazing rotors for my E bike. Just feels awesome when the levers are pressed. Stays firm and no warping whatsoever. I have this installed 2 months ago and am 100% satisfied
Review: Great stuff from shimano - Great stopping power. Very easy install. Fit is something you need to think of now. If your bike came with 180mm rotors you need a +23 mm post mount adapter. If your ride came with 160mm you need 43 mm post mount adapter. Also some frames can’t accommodate this rotor size so check your frame specs for max rear rotor size info. I Hope this helps someone and I’m not just mansplaining basic stuff to bike tech nerds.

These are fantastic. They are actually a combined 142g lighter then the cheaper Shimano rotors my bike came with. The stopping power is excellent.
