Vittoria AirLiner Light Gravel Polymer Insert 700x37/40

AirLiner Light Gravel 700x37/40 is a high-performance polymer insert engineered for tubeless gravel tires measuring 37–40 mm in width. By replacing part of the air volume inside the tire, it delivers smoother tire compression, enhanced control, and increased confidence on rough gravel surfaces.

The insert absorbs sharp impacts, protects the rim and tire from pinch damage, and improves sidewall stability when cornering at lower pressures. Its semi-permeable foam structure is fully compatible with tubeless sealants and allows limited riding even after a puncture by helping the tire stay seated on the rim.

Perfect for fast gravel rides, endurance events, and technical terrain, AirLiner Light Gravel combines low weight, protection, and refined ride feel in one smart solution.
