Vittoria Air-Liner Cyclocross Foam Tube Insert

Tire Insert

Welcome to the Cyclocross TLR revolution – eliminating burping even on the sharpest corners and off-camber terrain.
Air-Liner Cyclocross is designed to meet the unique demands of cyclocross, a sport where low tire pressure, sharp corners, and unpredictable terrain push riders and equipment to their limits.

Made from a lightweight foam material, it reinforces the tire structure without adding significant weight, preserving the speed and agility needed on the course. By stabilizing the sidewalls, it eliminates tire burping, ensuring the tire stays firmly seated during aggressive cornering, off-camber sections, and when clearing obstacles.

This insert also acts as an impact buffer, reducing the risk of rim strikes and pinch flats when using optimal low tire pressures. And when punctures do occur, its run-flat capability ensures you can still finish the race without having to shoulder your bike.

Each Air-Liner Cyclocross kit includes one Vittoria Multiway Tubeless Valve (60mm) for maximum airflow and a perfect tubeless setup. Lightweight, stable, and reliable – the ultimate insert for cyclocross racing.
