XT RT-MT800 Centerlock Disc Rotor
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.

Works great just like XT
- I've put it through the wringer
Looks great on any bike. Seems to cool itself down well. Got the 160mm one which has 4 spider arms (not 5). If you are confused like myself: XT got silver rotor, silver fins, black spider. XTR got silver rotor, black fins, black spider.

Hey Dmitry, The spline on the Shimano Lockring is the same as a Shimano Cassette, so you can use any Cassette Tool matched for a Shimano Cassette. One of my favorites is the Abby Bike Tools Dual Sided Crombie. That will work for SRAM, Shimano, and Campy!
