Kimberlite is a precious rock that often contains an even more valuable mineral — diamonds. The American Classic Kimberlite is as valuable to gravel riders as its namesake. For fast adventures on both pavement and gravel, look to the Kimberlite tire. This go-anywhere tire performs like a road tire on pavement and hooks up on hardpack dirt surfaces. The semi-slick tread starts with a smooth center for decreased rolling resistance on smoother surfaces, transitions thru progressively more aggresive zones for maximum lateral traction, and wraps up with robust edge knobs for dependable cornering. The Tubeless 120 TPI casing provides the ultimate construction for speed and comfort, and the Stage 5S Armor provides a tire that is lighter, faster, and more cut, tear, and abrasion resistant.
