Your cart is empty.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.

Ordered both the 180 and 160mm for a new set of Shimano wheels. Doing research ahead of ordering I knew the 160mm only has 4 spokes verses the 180's 5 spokes. Once they're mounted up on the bike it's not even really that noticeable. Came in brand new packaging from a Vendor I've never seen before(not an Amazon fulfillment) so I did have a bit of apprehension at first. Over all very satisfied.

I used it as a replacement of original disc for my mounrain bike. Easy to install, works perfect. The advantage is a cooling ring that helps prevent disc overheating, specially on California hot summer days.
