Vittoria Air-Liner Light MTB Insert 1AA00412

- Ultralight puncture solution for trail + XC tires\n- Provides all the pinch-flat resistance and tire performance boost of the Air-Liner MTB, but at a fraction of the weight\n- Ultralight construction also limits rotational mass above the bead, and it reinforces the sidewall while letting the tread ride on air\n- Contact patch stays fluid on terrain and punchy while pedaling, but the tire doesn’t flop or fold under lateral loads or while cornering\n- Prevents punctures, progressively ramping up under compression to eliminate rim strikes and snake bites when you over-send a line or catch a square edge\n- Expands after a flat and can be run flat \n- Valve included
