Ultralight puncture solution for trail + XC tires \n Provides all the pinchflat resistance and tire performance boost of the AirLiner 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 oversend a line or catch a square edge \n Expands after a flat and can be run flat \n Valve included
