Description
The Air-Liner is a premium polymer insert that replaces part of the air volume in your tyre. This feature, along with its unique shape, creates a customizable system that enhances your ride performance. The Air-Liner eliminates the traditional trade-off between stability and grip, keeping your tyres stable, grippy, and controlled, even at low pressures. Upon impact, the channel's corner edges flex first and progressively transition to the thicker section as the tyre compresses.
This allows the tread to stay flexible, boosting traction without compromising impact resistance. The round cross-section shape mirrors the tyre's natural form, providing greater contact within the sidewalls of the tyre casing. This increases side-to-side tyre stability while keeping the tread soft and grippy, thus improving cornering, climbing, and braking performance.
Features:
- Air-Liner increases control, durability, performance, and protection of both tyre and wheel
- Compatible with any wheel size (up to 700c), any tubeless valve, and tyre widths from 31c-40c
- The Vittoria Air-Liner is a tyre insert, designed for use in tubeless tyres
- Size: Up to 700c
- Width: 31-40c
- Weight: 47g
In addition to big-hit resistance, the Air-Liner Gravel lets you run a lower PSI, which lets your tyres gobble up stutter bumps that would otherwise filter up through the bike. You’ll still feel a connection through the contact patch, there’ll just be less static from gravel chatter – and less accumulated rider fatigue from that chatter filtering up through the seatpost and bar.
The Air-Liner Gravel’s profile reinforces the sidewall for stability while cornering, and it locks the tyre against the rim bead. It also lets the tread ride on air, maintaining contact-patch conformity for responsive traction while climbing and braking. No folding, no burping, no sluggishness, and no flats.
