Vittoria Air-Liner Gravel

The Air-Liner Gravel is designed specifically for tires ranging from 31mm to 40mm in width. If your tires fall outside this range, you will need to look for a different size insert to ensure proper fitment and performance.

While the insert is compatible with standard 3-way and 5-way tubeless valves, it comes with a high-airflow 5-way valve included. We recommend using the included valve to ensure optimal airflow and sealant distribution.

The closed-cell polymer construction is quite durable and rated for approximately 2,000 hours of normal riding conditions. After that, you may notice a degradation in the foam's structural integrity and impact absorption.

Installing tire inserts does add a step to the process, but the Air-Liner Gravel is designed to be relatively straightforward. Once you get the technique down for seating the bead, it becomes a routine part of your tubeless maintenance.

Yes, the primary benefit of the Air-Liner is that it provides a buffer against rim strikes and pinch flats, which allows you to safely run lower tire pressures for better traction and comfort on rough gravel.

Absolutely. By physically supporting the tire sidewalls and keeping the bead locked against the rim, the insert significantly reduces the risk of tire burping during aggressive cornering or high-impact riding.
