Air-liner Light Gravel, 700x37/40

- The ultralight puncture solution for gravel tires\n- The ultralight construction also limits rotational mass above the bead, and it reinforces the sidewall while letting the tread ride on air\n- 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\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 ran flat \n- Valve included
