## Overview

The Shimano Deore XT RT-MT800-M is a 180mm centerlock disc brake rotor featuring Ice Technology with an aluminum core and tapered fins for superior heat dissipation and fade resistance. Constructed from alloy steel with an aluminum carrier, it offers lightweight durability and seamless installation for high-performance trail and enduro cycling.

## Description

Bike progression has been forging ahead full-speed for some time now, and with all of the progress we see in bike geometry, riders are tackling the trail faster than ever. While this certainly is exhilarating when you've got the trail to yourself and you're booking it into banked berms, it also means you've got to dial in the ability to stop on a dime, should you come up on a climber working their way up the trail. Shimano's XT RT-MT800 Centerlock Disc Rotors are built to do just that, with Ice Technology and a deeper disc area to manage heat than an all-steel rotor can on its own. This tech combines an aluminum core sandwiched between steel extensions to provide better heat dissipation. This rotor is then paired up to an aluminum carrier, which further cools things down. This year's version ads in a tapered fin to help boost heat dissipation, and reduce fade, enabling better modulation and stopping power under pressure. The rotors are compatible with centerlock hubs only, and are available in a huge range of sizes to accommodate your gravel rig to enduro machine, and everything in between.
