?Vittoria Air-Liner
?MTB Tubeless Tyre Puncture and Rim protection
?Ultimate tyre accessory for mountain bike tyres
?Air-Liner is a foam based tubular insert for tubeless tyres designed to protect the rim, enhance grip and prevent punctures
?Air-Liner can be used on both standard wheels and tubeless-ready wheels, with both tubeless and tubeless-ready tyres, and with any type of sealant (preferably without ammonia)

?The Air-Liner is a high-quality polymer insert which replaces a portion of the air volume in the tyre. This trait, combined with the shape, provides a tunable system that enhances ride performance and allows your tyres to remain stable, grippy, and controlled, even at low pressures. Both wheel and tyre are protected by the Air-Liner insert, while eliminating flats caused by rim-strike impacts.
?Durability: Tested to a projected life of 2000 hours under normal riding, or 1 full hour of run-flat downhill use under a typical rider.
