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.
No longer will you fear the wrath of jagged rocks or treacherous roots, for Air-Liner Protect Downhill has your back.
TECHNOLOGY
Air-Liner Protect Downhill is made of a proprietary foam specifically designed for donwhill applications. The material is compatible with any type of liquid sealant. 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 (40mm) is provided in the pack.
FEATURES
IMPACT PROTECTION
Air-Liner Protect saves the rims from heavy impacts while reducing the risk of snake bites.
The "T" shape creates a barrier in between the rim edges and the inner side of the tire.
HIGH SPEED
Air-Liner Protect does not affect the tire rolling.
Under air pressure, the insert collapses on the rim creating a seal able to withstand even the strongest impacts.
With Air-Liner Protect, there is no foreign object rolling inside your tire.
LATERAL STABILITY
Air-Liner Protect sustains the tire sides under the load of cornering.
You can approach turns at full speed: no risk for your tires to coming off the rim.
Air-Liner Protect also increases the protection of the tire sidewalls from cuts and punctures.
BIG AIR VOLUME
Thanks to its "T" shape, Air-Liner Protect allows for bigger air volume inside your tire.
This means you can lower the air pressure and gain additional grip without any risk of unbeading your tire or damaging your rim.
