The chic V2 Tubeless valves come with a new Tyre Insert airflow system and many different colors. 6 slots milled into the base of the valve stem allow the valves to be compatible with most tubeless tire inserts. Through the slots can flow tubeless sealant fluid as well as air unobstructed. The V2 valves are made of aircraft aluminum 7075, so they are lighter and stronger than before!
