The bar can be held at a pressure point with a twist grip (TG), but the pulling force of the kite can now be varied variably. The wind window keeps its width and the steering lines turn out automatically. The TG allows buggy and ski rider a relaxed shoulder position because the "windward arm" is extended by the twist grip. Control impulses with one hand are very easy on the TG, without having to do without the power and depower functions.
