What Our Gearhead® Experts Are Saying: "The Racing Lab Skeleton is what I run when I want confidence on race day. It’s insanely light and rolls effortlessly, and the Race Ripost XC compound gives just enough rebound control to stay in contact through tricky sections. It’s made for speed, but feels incredibly stable too."Purpose-built for elite-level competition, the Hutchinson Skeleton 29in Tubeless Ready Racing Lab tire is the XC racer's secret weapon for dry, hardpack, and technical terrain. Developed with top athletes on the race circuit, the Skeleton blends rapid acceleration, razor-sharp handling, and Hutchinson’s most advanced compound and casing technologies into a race tire that’s anything but ordinary. The tread layout features a continuous center channel for maximum efficiency on climbs and straights, with squared, progressive shoulder knobs that bite confidently into corners without slowing you down. The Race Ripost XC compound—crafted with triple-density rubber—strikes the perfect balance between rebound control and grip, allowing the tire to conform to the terrain and hold traction over roots, rocks, and off-camber trail features. Reinforced with Hardskin bead-to-bead protection, this tire shrugs off flats while keeping weight impressively low for race day readiness.
