Części rowerowe Vittoria Airliner Medium 45 mm 2,25 - 2,50" 1115AL010M777BX

New tubeless system from Vittoria. The ring is mounted in the tubeless tire and allows you to drive on even if you have a puncture, as well as not having to use as much tubeless sealant and you also have the option of driving with even lower tire pressure. Also means that you can use less liquid and therefore in the end it weighs roughly the same as an alm. tubeless setup.The foam ring fits both a 26", 27.5", and 29" tire, as they are simply shortened in length. They fit tire width 2.2"5 - 2.50" and rim width 45 mm.Lasts for many thousands of kilometers, and the tire only needs to be changed when it is worn.
