Fly over the trails on the lightest and fastest tyre inserts.

Vittoria Air-Liner Light is the new insert for mountain bike tubeless tyres that enhances performance and capabilities of the wheel-tyre system for Cross-Country, Down-Country and Trail applications. Developed with XC pro riders and mechanics, and used at the MTB World Cup stages, Air-Liner Light is the lightest and fastest insert for tubeless mtb tyres available in the market.

Air-Liner Light is imperceptible and keeps the bike handling agile and fast. The insert allows for the progressive compression of the tyre when the tyre is under load. By doing so, Air-Liner Light enhances the ride feel while increasing stability and grip. In case of a puncture and consequent air loss, Air-Liner Light expands, offering the tyre support you need to reach the tech area to change the wheel, or the finish line, with minimal time loss.

Air-Liner Light also maximizes the tire puncture protection. Thanks to the unique foam formulation, the insert allows for extreme shock absorption and prevents punctures caused by heavy impacts with the rim walls (snake bites). Air-Liner Light is compatible with mountain bike tyre sizes 29”x2.1” up to 29”x2.4”, with rim channels 25mm up to 30 mm wide, and with any type of liquid sealant. Air-Liner Light must be used in combination with tubeless tyres and multiway tubeless valves only. The packaging of Air-Liner Light contains one insert and one Vittoria Green Multiway Tubeless valve 40mm long.

• The lightest insert in the market - 55g only - for Cross-Country, Down-Country and Trail tubeless tyes.
• Progressive compression of the tire under load provides increased stability, grip and excellent rim protection.
• In the event of puncture, it allows run-flat riding with minimal power dispersion.
