Vittoria Air Liner Road Tubeless Tyre Insert

The Air-liner is a high-quality polymer insert, which replaces a portion of the air volume in the tyre.

This trait, combined with the shape, provides a tunable system that enhances your ride performances. The air-liner destroys the traditional compromise of stability versus grip and allows your tyres to remain stable, grippy and controlled, even at low pressures. Upon impact, the corner edges of the channel flex first, and progressively build to the thicker portion, as the tyre is compressed. This allows the tread to remain flexible, which increases traction, without sacrificing impact resistance. The round cross-section shape mimics the natural shape of the tyre and supports a greater contact area within the sidewalls of the tyre casing. Side-to-side tyre stability is increased, yet the tread remains soft and grippy. This improves cornering, climbing, and braking performance.
