Vittoria Air-Liner Tire Insert

• Protects your rim and eliminates rim-strike flats by cushioning impacts from within the tire
• Reduced air volume allows the tire to compress and rebound in a more controlled manner than standard tubeless systems; designed for use in combination with tire sealant
• Increases side-to-side tire stability while keeping tire tread soft and grippy for improved cornering, climbing and braking performance
• Highly durable polymer material has been tested to a projected life of 2,000 hrs. under normal riding, with run-flat downhill performance proven by pro riders around the world
• Top V-channel makes room for the tunable air chamber beneath the tread; corner edges flex on impact and progressively build to the thicker portion for flexibility and traction
• Bottom V-channel allows easy fine-tuning of the air chamber
• Round cross-section mimics the tire shape to support a greater contact area within the sidewalls of the tire casing
• Proprietary, high-density polymer material is designed to eliminate the traditional compromise of stability vs. grip so your tires remain stable, grippy and controlled
• Completely waterproof material won't absorb tire sealant, ensuring consistent performance all season long and allowing your sealant to do its job
• Compatible with any wheel diameter up to 29 in. (equivalent to 700c or ISO 622); designed to be trimmed during installation for a perfect fit around your wheel
