Vittoria Air-Liner Tyre Insert

Vittoria presents Air-Liner, the ultimate tire accessory for mountain bike tires. Air-Liner is a foam-based tubular insert for tubeless tires designed to protect the rim, enhance grip and prevent punctures.

This technical foam is made up by a new-generation polymer, and the entire tube comes through coring process. Differently from printing and extrusion - cheaper production processes used for equivalent products available in the market - coring does not alter the chemical structure of the polymer. As a matter of fact, the added value of Air-Liner lays in its high-quality production process.

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.

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 run flat - calculation based on a rider of 80 kg of weight.

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"

Benefits:

• 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
