Vittoria Air-Liner Insert - Gravel

Rim and tire protection for your TLR Gravel bike.

For tyre size from 31mm to 40mm - Rim internal widhth up to 25mm max.

For gravel tyres larger than 40mm - use the small size MTB Air Liner

Works with 650b or 700c wheels - simply cut to length.

Weight = 47g prior to trimming.

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 beadlockfor your tire.

Control: Air-Liner GRAVEL 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 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.

Air-Liner GRAVEL is re-usable and very easy to install – as easy as mounting an inner tube inside your tire – and it is compatible with tubeless-ready tires only and with 3-way valves (in the packaging, a
5-way valves is provided for ultimate airflow). The insert can be used with sealant – preferably without ammonia.

Air-Liner GRAVEL is compatible with wheels of any diameter up to 29” (700c), and up to 25mm internal rim width. For ensuring the best fitment with any wheel, the insert has been designed to be cut according to the desired wheel diameter. 

For best results use Vittoria Universal Sealer - Ammonia Free & Latex Free.

 Handi tip - For gravel tyres larger than 40mm - use the small size MTB airliner.
