Bontrager XR4 Expert TLR Tire (27.5-inch / 650B)

The XR4 Expert is Bontrager's answer to loose, rocky trails. It's perfect if you're looking for an aggressive tire that rolls decently, grips hard, and rages through any obstacle in your path. To achieve that, its cupped lateral blocks and long, buttressed shoulder knobs hold your line when you're stuffing it into corners at speed. This Expert version has a lightweight folding bead to save weight for a more responsive, faster accelerating tire. And, this tire is tubeless-ready so you can trade in those tubes for improved traction and lower rolling resistance.
