Gravel Insert for Tubeless-Ready Bike Tires, Compatible with Any Wheel Size Up to 29", One Size

The Air-Liner GRAVEL is a high-quality polymer tire insert that takes the performance of tubeless-ready gravel tires beyond the limits Air-Liner GRAVEL is re-usable and very easy to install – as easy as mounting an inner tube on your tire – and it is compatible with tubeless-ready tires and with 3-way valves The Air-Liner GRAVEL insert absorbs impacts, preventing the risk of pinch-flats, while reducing tire burping at the bead, since the Gravel specific shape produces a bead-lock for your tire. The Air-Liner Insert replaces a portion of air volume inside the tire, allowing for lower pressure, and a more controlled deformation. This allows for better tire grip and less vibration. Vittoria is the official tire of USA Cycling. Tire choice of professional riders in the peloton. Winner of Tour de France, Giro d’Italia, Vuelta a España, Classics, World Championships, European Championships and Olympic Games.
