The Dualtron scooter Valve is designed for tubeless tires and is compatible with specific Dualtron models, including Dualtron Thunder, Dualtron 3, Dualtron Thunder 2, Dualtron Achilleus, Dualtron Storm, Dualtron Storm Ltd, Dualtron X, and Dualtron X2. Please note that this valve is unique and sensitive, so care should be taken during tire replacement to avoid cuts or damage. If you're not experienced with fitting tubeless tires, consider purchasing a tire already fitted on the rim, which eliminates the need for a separate valve. You can also contact us to request a tire pre-assembled on the rim. This product includes one tubeless valve.
