Vittoria Airliner Light XC Trail : 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 trail, XC, or down-country tire.
