Light, lean, and hungry for the podium, Shimano's XTR Tubeless Race wheels combine feathery light weight with exceptional strength and rigidity. With Scandium rims that weigh in at an unbelievable 350 grams, acceleration feels almost instantaneous. But for as light as these wheels feel they're ready for the worst the trail can throw at them, with burly, double-butted, stainless steel straight pull spokes. This wheel eats up aggressive turns, and uses Shimano's simple and effective Centerlock Rotor Mount so you can easily swap out disc rotors. UST compatibility means that tubeless setup is a snap, and provides low rolling resistance, improved traction and stability, and a decreased chance of pinch flats.
