Vittoria Air-Liner Light Tubeless Insert - XC Trail, 29 x 2.1-2.4"

The Air-Liner Light offers all the pinch-flat resistance and improved tire performance of the Air-Liner MTB, but it comes in at a significantly lighter weight—less than the sealant required to mount the tire. Its ultralight design minimizes rotational mass above the bead while reinforcing the sidewall, allowing the tread to ride on air. This design keeps the contact patch responsive on various terrains and maintains stability while pedaling, preventing the tire from flopping or folding during cornering and lateral loads.

Additionally, the Air-Liner Light is effective at preventing punctures. It progressively ramps up under compression to absorb impacts, helping to eliminate rim strikes and snake bites when you hit a rough line or encounter sharp edges. In the event that you do get a flat, the Air-Liner Light expands to fill the void, acting as a run-flat solution. This means you’ll enjoy greater stability, increased speed, enhanced puncture resistance, and improved responsiveness. Overall, the Air-Liner is a significant performance booster for any trail, XC, or down-country tire.
