The original Air-Liner for mountain bikes. It ramps up like a shock on big hits to protect the rim, buttresses the sidewalls for cornering, and keeps the tyre rideable for up to an hour after a flat.

Highlights

  • High-density polymer insert that ramps up under impacts
  • Prevents rim strikes, burping and bead unseating
  • Run-flat for up to an hour
  • Allows lower pressure and lighter casings
  • Four sizes from XC to fat bike
  • Sold individually

Why run an insert

More grip climbing and descending, better rim protection, lower pressures without burping, and less high-frequency vibration. Vittoria rates the life cycle at 2,000 hours in normal conditions, or one hour of run-flat riding (based on an 80 kg rider).

Compatibility & fit

Choose the size that matches your tyre width; every size suits 26, 27.5 or 29 in wheels. Works on standard and tubeless-ready rims, with tubeless and tubeless-ready tyres, any tubeless valve and any sealant, preferably ammonia-free. Sold as a single insert, so order two for a pair of wheels. 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.
