Vittoria Air-Liner Gravel

The Vittoria Air-Liner Gravel is the best possible protection against a flat tyre when you ride tubeless! The Air-Liner is placed inside your tubeless tyre; it is so lightweight you will hardly feel it's there. With the Vittoria Air-Liner Gravel you can always get your bike back home; if the air should get out, you can continue riding on the Air-Liner.

It is an absolutely ingenious construction: when the tyre is inflated, the Air-Liner shrinks to a minimal thickness so as not to get in the way of the latex sealant. Should you get a puncture, the latex seals it unless the hole is too big. In the latter case, the Air-Liner takes action. As soon as air gets into the tyre, it expands back to its original thickness to protect the rim. This way you can keep on riding without the bike becoming unstable.

Good protection and low weight
The Vittoria Air-Liner is made from a specially developed foam that allows it to flex when going over obstacles, yet is firm enough to hold the tyre in place in case of pressure loss. As it weighs only 47 grams, it is a lightweight in your wheels and a heavyweight when it comes to getting you home with a serious puncture.

Size | Range | Recommended | Internal rim width | Weight

• One-Size | up to 700x31/40 mm | 31-40 mm | max 25 mm | 47 g

• 1x Vittoria Air-Liner Gravel (with 1x 1x Vittoria 60mm Tubeless Multiway Valve)

Ensure that the rim tape and tubeless valves are fitted. On one side, completely fit the tubeless tyre onto the rim. Put the Vittoria Air-Liner in place underneath the tyre in the same way as you would an inner tube. Then fit the other side of the tyre to the rim, using tyre levers if necessary. Pressurise the tyre to align it correctly with the rim. Then remove the valve core and add 30-60 ml of latex. Screw the valve core back into the valve. Bring the tyre up to pressure and bounce it to distribute the latex. Also, do a test ride to distribute the latex and hang the wheel in the shed overnight. The next day, check if the tyre is still at the right pressure. If not, repeat the process and add more latex.
