Shimano's MT66-29 Wheelset gets your 29er over whatever obstacles stand in its path. The rim and hub are aluminum for low weight, and the stainless-steel spokes hold up to almost anything you've got. The rim is tubeless ready, so you'll get loads of smooth-rolling stability and superior traction. Shimano angular contact bearings roll smoothly and have great lateral stiffness for perfect cornering at any speed. Plus, Shimano's Center Lock rotor mount makes for easy installation, and Shimano's 15mm front and 12mm rear E-Thru axles add strength to these wheels, improving steering and handling on the trail.
