Vittoria AirLiner Cyclocross Tire Insert 700x31-33C

The Vittoria AirLiner Cyclocross 700x31–33C is purpose-built for cyclocross competition, where traction, control and reliability matter most. Lightweight foam reinforcement stabilizes the tire without sacrificing speed, keeping handling precise through sharp corners, off-camber sections and barriers.

By supporting the sidewalls, the insert prevents tire bounce and maintains a consistent contact patch at low pressures. It also protects the rim from hard impacts and pinch flats, allowing riders to push harder on unpredictable courses. In the event of a puncture, the Run Flat capability lets you finish the race instead of running to the pits.

Each insert includes a Vittoria Multiway Tubeless Valve (60 mm) for optimal airflow and a perfect tubeless setup. Compatible only with ammonia-free sealants.

Light, stable and race-proven – the ultimate insert for cyclocross racing.
