Vittoria Air Liner MTB L 50mm (2.5-2.7)

The original Air-Liner system for tubeless stability, impact protection, and compatibility with 26/27.5/29 wheels
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.

Air-Liner is designed considering all the demands of each mountain bike discipline:

Size S – Cross-Country / Marathon – from 1.9” to 2.2”
Size M – All Mountain / Enduro – from 2.25” to 2.5”
Size L – Enduro / Plus – from 2.5” to 2.7”
Size XL – Plus / Fat – from 2.7” to 4.0”

Air-Liner can be used on both standard wheels and tubeless-ready wheels, with both tubeless and tubeless-ready tires, and with any type of sealant – preferably without ammonia. In addition, it fits any type of valve for tubeless.

Air-Liner advantages are countless:

• More grip, in both climbing and descent
  
• Enhanced rim protection
• Allows for lower tire pressures
  
• Prevents burping effect
  
• Prevents bead breaking
• Absorbs high-frequence vibrations. Comfort increased.
  
• Allows for tires with lighter casing
  
• Although Air-Liner polymer is slightly dense, it is very resistant. This particular structure provides the insert with light weight without compromising on resistance and duration: Air-Liner weight goes from 160 g to 220 g according to the size, and the product life cycle is 2,000 hours in normal conditions or one-hour runflat – calculation based on a rider of 80 kg of weight.
