Air-Liner GRAVEL takes the performance of tubeless-ready gravel tyres beyond the limits. Given the success and positive results achieved by Air-Liner mountain bike version, Vittoria decided to push the product beyond the MTB spectrum and to develop an innovative insert that could support tubeless-ready tyres for gravel applications.
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 tyres only and with 3-way valves (in the packaging, 5-way valves are provided for ultimate airflow). The insert can be used with sealant – preferably without ammonia. Air-Liner GRAVEL advantages are countless: Protection: The Air-Liner GRAVEL insert absorbs impacts, preventing the risk of pinch-flats, while simultaneously reducing tire burping at the bead, since the Gravel specific shape produces a bead-lock for your tyre. Control: Air-Liner GRAVEL replaces a portion of air volume inside the tyre, allowing for lower pressure, and a more controlled deformation. This allows for better tire grip, and significantly reduced handlebar vibration when compared to a standard tubeless-ready set-up. Performance: Air-Liner GRAVEL increases lateral stability without compromising grip and adherence. This allows for better cornering, climbing and braking performance. Durability: The polymeric material of Air-Liner GRAVEL is extremely durable. In normal conditions, it lasts up to 2000 hours of use; or 1 hour completely run-flat.
