We aren't exactly sure what the word Deore originally meant, but everyone associated with mountain biking knows what it means now. It means quality. From the very first component, Deore XT has been Shimano's workhorse gruppo. Nothing has changed. Deore XT isn't Shimano's lightest. Nor is it Shimano's most expensive. It is, however, Shimano's best all-around component group, and its reputation as the toughest in Shimano's lineup without significant weight sacrifices has stood the test of time. For the mountain biker about to take the leap into the 650B category of bikes, we can't think of a better wheelset on which to base that leap than the Shimano Deore XT WH-M785 27.5-inch wheelset.

Starting from the inside out, Shimano uses its Deore XT hubs for the WH-M785's. The hubs feature sealed bearings for virtually maintenance-free operation in any riding conditions. The hubs are Center Lock-compatible. Shimano uses butted (2.0-1.5-2.0) round straight-pull spokes. The rims, optimized for durability and light weight, are 19mm deep and 23.4mm wide. Shimano recommends tire widths of 1.5 to 2.25 inches. The rims are, of course, UST-compatible.

The Shimano Deore XT WH-M785 27.5 Wheelset is available in two configurations. Both come with a 15 x 100mm thru-axle front hub and you have the choice of 10 x 135mm quick-release or 12 x 142mm thru-axle rear wheels.

  • XT hubs
  • Front 15mm thru-axle
  • Rear 10x135mm or 12x142mm thru-axle

Do you need an adapter to run 6-bolt rotors?

Hey Patrick, yes you would need an adapter centerlock rotors for this wheelset. If you have any other questions, feel free to reach out to me directly.


Can the front wheel be converted to QR

They are 110x15mm QR up front and 146x12mm QR in the rear. The hubs are Center Lock-compatible. Shimano uses butted (2.0-1.5-2.0) round straight-pull spokes. So the front is QR compatible

Mark - what is a 146x12 QR?

110x15 is actually boost spacing, and I am sure that is an error as well, but at least that is a thing...

Do you use rim tape and sealant for xt...

Do you use rim tape and sealant for xt wheelset if you go tubeless and if it comes with tubeless valves?- thanks

Best Answer

The rims are UST certified, so if pair with a UST tire, they wouldn't need sealant. Not running sealant kind of defeats the puncture resistance advantage of running tubeless, so I would personally still use sealant with both a UST and a non UST or tubeless ready tire. The rim does not need a rim strip, but if using sealant, it's never a bad idea to have a layer of Stans tape down.
