Developed by Lisa Wilcox and Ernst Hoyos together with Sprenger is a double jointed bit that features a unique roller which provides a gentle stimulation to the tongue which encourages the horse to chew, prompting salivation, allowing the acceptance of the bit therefore the relaxation of the jaw. Lisa states "It has been Ernst and my experience that through this gentle stimulation our horses learn more quickly to accept the bit softening their entire top-line enabling us to perform the movements with more relaxation, and ultimately more harmony." Stainless steel rings with a Sensogan mouthpieceMouthpiece width: 16mmInside ring diameter: 70mm A little more about Sensogan: SENSOGAN® – the new bit material developed by Sprenger – is the result of additional development and consequently the improvement of our original material, Aurigan. We have built on the success and positive features of Aurigan, specifically the taste and salivation aspects to give an even more delicate and sophisticated connection to the horse. It is the distinctive composition of copper, manganese and zinc that makes SENSOGAN® so special. With a reduced copper content the oxidation process is still maintained, however, the extraordinary combination with manganese is what makes the difference. This combination results in a smoother and more regulated process of oxidation. Tests show a very positive influence on the horse’s satisfaction, motivation and willingness to perform. The copper discharge quantity into the horse’s saliva is reduced considerably, which helps to keep the noble white- gold colour for a longer time. The new ingredient manganese on the other hand is an important micronutrient. As a crucial component and activator of enzymes, manganese is highly relevant for building up connective tissue as well as for the muscle and energy metabolism. It can therefore be helpful in preventing muscle tension and in supporting stress reduction. Beyond that, manganese is needed for the reduction of histamine and can prevent allergic skin reactions. Also, the feed industry discovered manganese to be a promising food additive that is gaining in importance in modern feeding of sport horses.
