Vittoria Air-Liner Tyre InsertVittoria 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"
