Race day rim protection at zero rotational weight in the Vittoria Air Liner Light XC

The Vittoria Air Liner Light XC is engineered as the lightest XC tubeless tire insert in the Vittoria lineup, developed with World Cup XC teams who needed pinch flat protection without rotational weight penalty. At just 55 grams per insert, it weighs less than the sealant required to mount the tire, so it disappears under race pace until the moment a square edge or rough rock garden tries to take your rim. The proprietary open cell foam reinforces the sidewall against lateral loads while letting the tread ride on air for a fluid contact patch and snappy acceleration.

Engineered for tubeless tires only with multiway tubeless valves and ammonia free sealant, the Air Liner Light XC progressively compresses under impact to eliminate rim strikes and snake bites, then expands in the event of a flat for up to 25 km of run flat capability. The right pick for XC racers, marathon riders, down country builds, and Pacific Northwest trail riders who run lower pressures for grip on roots and rocks and need rim protection insurance.
