Vittoria Air-Liner Protect Downhill - 29x2.4/2.6

The Air-Liner Protect Downhill tire insert is born on the most challenging DH tracks of the UCI Mountain Bike World Series. Made from high-density polymer foam that ensures long-lasting durability and product resistance, it allows riders to confidently tackle even the most extreme descents. It provides a robust barrier between the rim and the tire, offering unprecedented protection against punctures, sidewall cuts, and pinch flats. The Air-Liner Protect Downhill version uses a denser foam compared to the enduro version, meticulously designed to withstand the extreme, relentless forces encountered in high-speed descents. Unlike its predecessor, the Air-Liner Protect Downhill comes as a complete ring, with the ends already welded, eliminating the need for cuts and ties. You will no longer fear sharp rocks or treacherous roots: Air-Liner Protect has your back.
