Developed on UCI World Series downhill tracks. The Air-Liner Protect Downhill puts a dense foam barrier between tyre and rim to fight pinch flats, sidewall slashes and rim damage at race speed.

Highlights

  • High-density expanded polyurethane, denser than the Protect Enduro
  • Complete loop: no cutting or zipping
  • Run-flat for up to 50 km
  • Lateral stability for cornering
  • eMTB compatible; tubeless valve included

Built for gravity

The higher-density foam is made to withstand repeated hard hits on rough DH and bike park tracks, and lets you run lower pressure for grip without folding the tyre.

Compatibility & fit

For tubeless 27.5 in tyres 2.4-2.6 in wide. Tubeless set-ups only (not with inner tubes) and Multiway tubeless valves only; a valve is in the pack. Compatible with any liquid sealant and rated for eMTB use. A 29 in version is also made. Fitting an insert is part of a tubeless set-up, a separate workshop service; the Tune Cycles workshop can fit it for you.

Vittoria covers its products against defects in materials and manufacture. Normal wear, punctures, impact damage and damage from incorrect fitting are not manufacturing defects. Your rights under the Australian Consumer Law also apply. For warranty support, return the product to Tune Cycles and we'll manage the claim with Vittoria's Australian distributor.
