Vittoria Air-Liner Light Gravel Tyre Insert

Whether you're chasing PBs on a gravel race course or loading up for a multi-day bikepacking trip, the Air-Liner Light Gravel is designed to make your tubeless setup more comfortable, more capable, and far less likely to end your ride early.

Fitted inside a tubeless gravel tyre (37–50mm), the insert works in three ways: it protects your rim and gives run-flat capability if you do puncture, it lets you run lower tyre pressures for extra comfort and grip without the risk of rim strikes, and it improves lateral stability through corners for more confident, faster riding on loose or uneven surfaces.

Built as a single superlight foam loop in Vittoria's signature green, the insert adds negligible weight and has next to no impact on rolling performance, while still cushioning impacts on rough gravel roads and reducing the risk of snake-bite punctures. Each insert comes with a 60mm Vittoria Multiway tubeless valve included, ready for a proper tubeless setup.
