Vittoria Air-Liner Tyre Insert Medium 45mm for 2.3-2.50"

This VITTORIA Air-liner M anti-trap foam is suitable for 26, 27.5 and 29 inch tubeless MTB rims with a tire width between 2.25" and 2.5", ideal for trail and all-mountain.

The innovative technology is based on a foam ring that is incorporated into the inside of the tubeless tire, providing a simple but effective way to combat punctures. This high-density foam, which comes into contact with the rim tape and sidewalls of the tire, is designed to intercept and absorb large impacts to protect the rim and tire. The foam allows riding with low air pressure and has other advantages: It is easy to install, lightweight, durable and preventive waterproof.
