Vittoria Air-Liner Light Gravel - 700x37/40

Vittoria Air-Liner Light Gravel: Tubeless Insert for 700x37/40 Tires

The Air-Liner Light Gravel is a tubeless insert specifically designed for gravel tires with widths between 37 and 40 mm, available in the 700c size. This innovative insert represents the evolution of Vittoria technology, combining the expertise of the previous Air-Liner Gravel with the advances of the Air-Liner Light XC. The expanded foam structure provides impact protection and significantly reduces the risk of punctures, a critical feature for those who practice bikepacking or cycling touring on rough terrain. The super-light ring keeps weight down without compromising strength, making it ideal for cyclists seeking a balance between performance and reliability on mixed routes.

Exclusive compatibility with tubeless tires and multiway tubeless valves ensures an integrated, high-performance system. The insert optimizes wheel dynamics, improving grip on uneven surfaces and increasing cornering support, essential factors for riding on gravel. The recommended rim width is 23-25 mm, a key parameter to ensure correct installation and maximum benefit from the puncture-protection technology. The package includes the insert and a green Vittoria 40 mm multiway tubeless valve, providing everything needed for immediate installation.

For endurance cyclists and off-road adventure enthusiasts, the Air-Liner Light Gravel is a technical solution that goes beyond simple protection. The system reduces vibrations transmitted to the rim, protecting it from impacts and extending its service life. The technology enables higher riding speeds thanks to reduced internal friction and improved stability. This insert is particularly suited to those tackling long distances over varied terrain, where reliability and puncture resistance take priority over absolute weight.
