Product details:
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.
