SIA = control pulse adapter or Direct-to-bar adapter
The SIA enables all sizes of the Nasa Star (from 2.5m to 12.5m) to be connected directly to a suitable bar.By using the 3 line system with the SIA (Direct-to-bar adapter) you can set any amount of depower on the kite when streetkiting. This also allows for a considerably greater wind range per kite size.
Three knot sliders (red, yellow and blue 'Overcoat') cover the connecting knots thus preventing any fouling and devourof the lines.
