FAQ

What does a tire insert actually do?: The Air Liner Light Gravel sits inside your tubeless tire and protects the rim from pinch flats and impact damage. It lets you run lower tire pressures for better grip and compliance, and if you flat, the foam keeps the tire on the rim so you can ride out under control instead of stopping on the side of the trail.

Is the Air Liner Light Gravel tubeless ready only?: Yes. The Air Liner Light Gravel must be used with tubeless ready tires and multiway tubeless valves only. It is not compatible with inner tubes.

How does this compare to other gravel inserts?: At 45 grams per insert, the Air Liner Light Gravel is the lightest dedicated gravel insert in the Vittoria lineup. The foam is non absorbent so it does not soak up sealant, a common issue with other foam inserts. Best matched to racers and fast gravel riders who want puncture insurance without weight penalty.

Best For

Built for gravel racers, gran fondo riders, and bikepackers running narrower 37 to 40 mm tubeless gravel tires who want the lightest possible insert. Pairs particularly well with Pacific Northwest mixed terrain where lower tire pressures unlock grip on roots and loose surfaces, but rim strikes are a constant possibility. Also a strong choice for endurance gravel events where flatting is not an option.
