Vittoria Air-Liner Tubeless System: 2.25 - 2.50", MD

Air-Liner is a foam-based tubular insert for tubeless tires designed to protect the rim, enhance grip and prevent punctures. Air-Liner comes as a tube with two continuous carvings – one at the top and one at the bottom of the tube – designed to make room for the air and sealant within, and to better support the tire. In the packaging, Air-liner comes with a zip tie to close the tube on the rim. As the Air-Liner length always exceeds the wheel diameter, you need to cut the edges of the tube according to the size of the rim (you can use a cutter for this processes). After that, you need to make two holes – one for each extremity of the tube – and insert the zip tie in the two through holes (you can use a screwdriver for making the holes). Apart from this process, the mounting of the Air-Liner is not too different from the one of inner tubes. To facilitate the mounting even more, Vittoria suggests lubricating the insert with some water.
