The Vittora Air-Liner Tubeless Tire Insert is a high-quality polymer insert, which replaces a portion of the air volume in tires. This trait, combined with the shape, provides a tunable system that enhances your ride performances. The Air-Liner destroys the traditional compromise of stability vs. grip, and allows your tires to remain stable, grippy, and controlled, even at low pressures.
The Air-Liner is designed using a round cross section, with channels on the top and bottom. The top channel provides room for the tunable air chamber that sits directly beneath the tire tread. Upon impact, the corner edges of the channel flex first, and progressively build to the thicker portion, as the tire is compressed. This allows the tread to remain flexible, which increases traction, without sacrificing impact resistance. The bottom channel allows for easy fine-tuning of the air chamber, and allows for full compatibility of all valve core styles.
The Vittoria Air-Liner Tubeless Tire Insert is available in 4 sizes, and is compatible with all makes and models of tires. Small: 1.9" - 2.25", Medium: 2.25" - 2.5", Large: 2.5" -2.7", X-Large: 2.7 - 4.0".
