All-mountain riding has spawned some truly impressive bikes that are both light and tough, and having the right wheels maximizes the action. Shimano's Deore XT wheels fit the bill beautifully with their stiff tubeless rims, fully rebuildable precision angular-contact bearing hubs, and stout 15mm front through axle. The rear XT hub gives you quick engagement and minimum drag, too, so it's perfect for technical riding and those last-second wheelie drops. The 12mm-through axle stiffens up the rear end for precise tracking and cornering too. The 21mm-wide rims add beefiness while supporting nice, fat tires, and Shimano's Center Lock rotor mounts make disc installation and removal a breeze.
