Named after the airport code of Leadville, Colorado, home of the legendary Leadville 100, Clement's XC LXV is a cross-country tire that wants to rack up mega miles. Low shoulder knobs and fast-rolling center tread helps this tire excel on hardpack. The lightweight, high-volume casing features a folding bead, supremely supple sidewalls and incredible cornering traction. A bead-to-bead layer of Kevlar flat barrier adds puncture protection without adding weight, letting you put it all on the line with confidence.
