What is the Vittoria Air Liner Light Gravel built for?

The Vittoria Air Liner Light Gravel is engineered as the lightest gravel oriented tire insert in the Vittoria lineup, designed for racers and gran fondo riders who want serious puncture and rim protection without the weight penalty of traditional foam inserts. The proprietary green foam loop runs flat capable, lets you drop tire pressure for better grip and compliance, and protects the rim from pinch flats and impact damage when the gravel turns rough. The insert weighs just 45 grams, so adding the protection costs effectively nothing in real world rotating weight.

Engineered to work with tubeless tires and multiway tubeless valves only, the Air Liner Light Gravel uses a non absorbent foam that does not soak up sealant. Each package includes one insert and one 40mm Vittoria Green Multiway Tubeless valve. The right pick for gravel racers chasing the lightest possible setup, bikepackers heading deep into remote terrain, and Pacific Northwest gravel riders who run lower pressures for chunky terrain and need the rim protection insurance.
