Vittoria Gravel Air-Liner Light Adds Lightweight Run-Flat Protection
Briefly

Vittoria Air-Liner Light Gravel tire insert uses semi-permeable foam to fill the tire if punctured, enabling riders to keep rolling with expanded foam pressure until a proper fix is performed.
The tire insert provides a quasi-suspension effect, supporting tires at lower pressures, preventing pinch flats, and enhancing the overall riding experience, as attested by the Editor's Choice award.
Retailing at $69.99 per tire and weighing 40-45g, Vittoria's inserts are compatible with tubeless gravel tires ranging from 42-50mm mounted on 23-25mm wide rims in both 650B and 700c sizes.
