A kite control bar having a tensioning bar end float which is capable of expanding and contracting. When an adjusting force is exerted upon the trim line, the trim line to backline leader connection pushes the bar end float from an expanded state to a contracted state. When the adjusting force is released, the bar end float tends to return to its expanded state. This ensures that constant tension is maintained on the trim line to prevent excess line from tangling inside the kite bar and bar end float while depowering.
