Air-Liner Protect Downhill

Air-Liner Protect Downhill – Ultimate Protection for Extreme Trails

Born from the toughest downhill race courses of the UCI Mountain Bike World Series, the Air-Liner Protect Downhill tire insert is built to withstand the most extreme conditions. Crafted from high-density polymer foam, it delivers exceptional durability and long-lasting performance. Designed to provide a solid shield between the rim and tire, this insert offers unparalleled defense against punctures, sidewall cuts, and pinch flats—allowing you to ride with confidence on the most demanding terrains.

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.
