The second version (V2) features an increased hose diameter compared to the original valves on the kite's leading edge. The upgraded V2 valves maintain a higher standard and make it easier to inflate and deflate the structure of the kite. To align with the new hoses, a complete replacement of bladders is recommended. Valves and hoses are included for a seamless upgrade. If you have any questions, feel free to contact us at info@boardclub.se.
