Vittoria Air-Liner Light XC Trail

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.

Requires use of an Ammonia free tubeless sealant - for best results use Vittoria Universal Sealer - Ammonia Free & Latex Free.

The Air-Liner Light provides all the pinch-flat resistance and tire performance boost of the Air-Liner MTB, but at a fraction of the weight – it weighs even less than the sealant you need to mount the tire. 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.

It does, of course, also prevent punctures, progressively ramping up under compression to eliminate rim strikes and snake bites when you over-send a line or catch a square edge. If – or rather – when you do eventually flat, the Air-Liner Light expands to fill the void as a run-flat. More stability, more speed, more puncture resistance, and more snappy reactivity – the Air-Liner is a force multiplier for every quality you want in a trail, XC, or down-country tire.

A high-density polymer structure gives the Air-Liner Light all the qualities of a good shock: it mutes chatter and ramps up under big impacts, increasing ride comfort and preventing rim strikes. It also acts as a run-flat for up to an hour if you do puncture, and it has an install life of 2,000 hours. The Air-Liner Light’s cross-section rides low in the rim, keeping the tread lively and reinforcing lateral stability. The Air-Liner is compatible with ammonia-free sealant, multiway tubeless valves, 29 x 2.1-2.4in tubeless tires, and rim channels of 25-30mm. Its waterproof coating prevents the absorption of sealant. Each Air-Liner Light insert includes a 40mm Vittoria Green Multiway Tubeless Valve.
