Vittoria Air Liner Tire Insert MTB

The puncture solution for mountain bike tires

Punctures are a fact of life, but the Air-Liner MTB keeps a mid-run flat from imposing an insurmountable time penalty, an auto-DNF, or a hike-a-bike to the transition. The Air-Liner’s high-density structure keeps your tire rideable for up to an hour after a flat – enough time to clear a stage or hustle back to the trailhead. Your ambitions don’t have to deflate just because your tire did.

The Air-Liner isn’t just an emergency flat solution – it also helps prevent punctures by preventing rim strikes. As it compresses, the polymer material ramps-up like a shock. Trail chatter is muted, root lattices are smoothed, and the big hits and square edges of rock gardens are cushioned. The Air-Liner’s cross-section keeps the tire’s contact surface fluid and flexible, but it also increases lateral stability by buttressing the sidewalls.
