VITTORIA AIR-LINER PROTECT DOWNHILL

VITTORIA AIR-LINER PROTECT DOWNHILL

Maximum protection on the most extreme Downhill trails: you will no longer fear sharp rocks or treacherous roots: Air-Liner Protect has your back.
The Air-Liner Protect Downhill tire insert was born on the toughest DH courses of the UCI Mountain Bike World Series. Built from high-density polymer foam that guarantees long product life and durability, it allows riders to tackle even the most extreme descents with confidence. It provides a robust barrier between rim and tire, offering unprecedented protection against punctures, sidewall cuts, and pinch flats. The Air-Liner Protect Downhill version uses a higher-density foam than the enduro version, meticulously engineered to withstand the extreme, relentless forces encountered on high-speed descents. Unlike its predecessor, Air-Liner Protect Downhill comes as a complete ring, with the ends already welded, eliminating the need for cutting and zip ties.

Technology
Air-Liner Protect Downhill is made with a high-density expanded material formula specifically designed for downhill needs. The material is compatible with any type of liquid sealant. It is available in 2 wheel sizes (27.5" and 29"), each compatible with tires from 2.4" to 2.6". It must be used only with tubeless set-ups (not compatible with inner tubes) and only with multi-way tubeless valves – one valve is included in the package.

VITTORIA AIR-LINER PROTECT DOWNHILL MAIN FEATURES:

• Air-Liner Protect protects rims from heavy impacts and reduces the risk of snakebites.
• The “T” shape creates a barrier between the edges of the rim and the inner side of the tire.
• Air-Liner Protect does not affect tire rolling.
• Under air pressure, the insert collapses onto the rim, creating a seal capable of withstanding even the hardest impacts.
• With Air-Liner Protect, no foreign object can roll around inside the tire.
• Air-Liner Protect supports the tire sidewalls under cornering load.
• You can take corners at full speed: there is no risk of your tires burping off the rim.
• Air-Liner Protect also increases sidewall protection from cuts and punctures.
• Thanks to its “T” shape, Air-Liner Protect allows you to increase the air volume inside the tire.
• This means you can lower air pressure and obtain greater grip without risking damage to the tire or rim.
