The ultralight XC tubeless liner system built for speed. Eliminate pinch-flats and bead-burping like a World Series pro

The Air-Liner Light provides all the pinch-flat resistance and tire performance boost of the Air-Liner MTB, but at a fraction of the weight – it weighs even less than the sealant you need to mount the tire. The ultralight construction also limits rotational mass above the bead, and it reinforces the sidewall while letting the tread ride on air. The contact patch stays fluid on terrain and punchy while pedaling, but the tire doesn’t flop or fold under lateral loads or while cornering.
It does, of course, also prevent punctures, progressively ramping up under compression to eliminate rim strikes and snake bites when you over-send a line or catch a square edge. If – or rather – when you do eventually flat, the Air-Liner Light expands to fill the void as a run-flat. More stability, more speed, more puncture resistance, and more snappy reactivity – the Air-Liner is a force multiplier for every quality you want in a marathon, XC, or down-country tire.

The Air-Liner Light XC, weighing just 55 g and developed in collaboration with World Cup teams, delivers outstanding performance in puncture protection and riding comfort, ensuring up to 25 km of run-flat capability when ridden cautiously.
The Air-Liner Light XC is compatible with 29" wheels featuring rim channels ranging from 25 mm to 30 mm and tires with widths between 2.1" and 2.4".
This insert is designed exclusively for tubeless tires and must be used with multiway tubeless valves and ammonia free sealant only.
Each package includes one insert and a 40 mm Vittoria Multiway tubeless valve.

• The lightest insert in the market - 55g only - for Cross-Country, Down-Country and Trail tubeless tyes.
• Progressive compression of the tire under load provides increased stability, grip and excellent rim protection.
• In the event of puncture, it allows run-flat riding with minimal power dispersion.
