Shimano XT RT-MT800 Centerlock Disc Rotor

For some time now, bike progression has been forging ahead at full-speed, and with all the progress we see in bike geometry, riders are tackling the trail faster than ever. This certainly is exhilarating when you've got the trail to yourself and you're booking it into banked berms, but 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. The current year's version adds 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.

Regarding the materials, the rotor is made of steel, while the carrier is crafted from aluminum. The attachment type is centerlock, and the compatibility is also centerlock wheels. The available diameters include 140mm, 160mm, 180mm, and 203mm. In terms of claimed weight, the 140mm version weighs 3.1oz (89g), the 160mm version weighs 3.8oz (108g), the 180mm version weighs 4.6oz (131g), and the 203mm version weighs 5.2oz (147g).

The rapid progression in bike technology has enabled riders to tackle trails at unprecedented speeds. However, this also necessitates the ability to stop quickly and safely, particularly when encountering other trail users. Shimano's XT RT-MT800 Centerlock Disc Rotors are designed to meet this challenge, leveraging advanced materials and engineering to provide superior heat dissipation and stopping power.

The rotors' unique construction, combining an aluminum core with steel extensions, and the addition of an aluminum carrier, allow for enhanced thermal management. This, in turn, translates to better modulation and consistent braking performance, even under the most demanding conditions. The range of available sizes ensures that riders can find the perfect fit for their specific bike and riding needs, from gravel to enduro.
