Vittoria Air Liner Protect Downhill tyre protection

Extreme protection on the DH tracks: No longer will you fear the wrath of jagged rocks or treacherous roots, for Air-Liner Protect Downhill has your back

The Air-Liner Protect Downhill tire insert originates from the most demanding downhill race trails of the UCI Mountain Bike World Series. Constructed from high-density polymer foam ensuring long-lasting product life, it allows riders to confidently tackle even the most demanding trails and terrains. It provides a robust barrier between the rim and the tire, offering unprecedented protection against punctures, sidewall slashes, and pinch flats. The Air-Liner Protect Downhill version boasts a higher density foam compared to the enduro version, meticulously engineered to withstand the relentless forces encountered during high-speed descents. Unlike its predecessor, Air-Liner Protect Downhill come as a complete loop, eliminating the need for tedious cutting and zipping.

It comes in 2 wheel sizes (27.5” and 29”), each compatible with tire size 2.4" to 2.6". It must be used with tubeless set-ups only (not compatible with the use of inner tubes) and with multiway tubeless valves only - a valve is provided in the pack.
