VITTORIA AIR-LINER LIGHT GRAVEL Tubeless Tire Insert : 700x37-40 mm

The Vittoria Air-Liner GRAVEL is an insert for tubeless-ready gravel tires. Re-usable and very easy to install – as easy as mounting an inner tube on your tire – the Air-Liner GRAVEL is compatible with tubeless-ready tires only and with 3-way valves (5-way valves included for ultimate airflow). The insert can be used with sealant (ammonia-less recommended).

• The ultralight puncture solution for gravel tires
• 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
• 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
• Expands after a flat and can be ran flat
• Valve included
