VITTORIA AIR-LINER PROTECT DOWNHILL

Maximum protection on the most extreme Downhill courses: No more worrying about sharp rocks or tricky roots – Air-Liner Protect has got your back!
The Air-Liner Protect Downhill tire insert is born from the toughest DH courses of the UCI Mountain Bike World Series. Built from high-density polymer foam that guarantees long-lasting durability and resilience, it allows riders to tackle even the steepest descents with confidence. It provides a strong barrier between the rim and tire, offering unprecedented protection against punctures, sidewall cuts, and pinch flats. The Air-Liner Protect Downhill version uses a higher-density foam compared to the enduro version, meticulously engineered to withstand the relentless, extreme forces encountered in high-speed descents. Unlike its predecessor, the Air-Liner Protect Downhill comes as a complete ring with the ends already sealed, eliminating the need for cutting and zip ties.

Technology
Air-Liner Protect Downhill is made from a high-density foam material formula, specifically designed to meet the demands of downhill racing. 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 only be used with tubeless setups (not compatible with inner tubes) and only with multi-way tubeless valves – one valve is included in the package.

• Air-Liner Protect protects rims from hard impacts and reduces the risk of snake bites.
