Downhill insert
Vittoria Air-Liner Protect Downhill Tyre Insert
The densest Air-Liner Protect, built for downhill and bike-park riding where rim strikes are frequent and heavy. Its T-section foam shields the rim and sidewalls while leaving room for low, grippy pressures.
Highlights
Why we rate it
Highest-density foam
Firmer than the Enduro insert to resist the repeated, high-speed impacts of downhill tracks.
Low pressure, high grip
The T profile keeps air volume up so you can drop pressure for traction without folding the tyre.
Full protection
Guards against punctures, pinch flats and sidewall cuts as well as rim damage.
Closed loop
Pre-formed ring that fits without cutting or zipping.
