Herm Sprenger - Dynamic Loose Ring Snaffle Bit - 14 mm - Sensogan Coating - Double Joint The Herm Sprenger Dynamic RS Sensogan® Loose Ring Bit features the innovative Sensogan mouthpiece metal. As a result of ongoing research and development, experts at Herm Sprenger have created Sensogan for a mouthpiece that offers all the benefits of Aurigan®, yet retains its discreet and elegant silver color much longer. Like Aurigan, Sensogan promotes a delicate and sensitive connection to the horse. It instills a pleasant taste, encourages salivation and promotes bit acceptance. It also significantly regulates the oxidation process to allow the bit to maintain its beautiful color. Distinctively unique, this metal is a propriety blend of copper, zinc and manganese. A reduced copper content allows some oxidation to occur, but the addition of manganese regulates and slows oxidation which in turn slows discoloration. Manganese is also an important micronutrient for horses, as a crucial component and activator of enzymes. All Sensogan bits are marked with a black ring at the cheeks. The Herm Sprenger Dynamic RS Sensogan® Loose Ring Bit is designed to give soft, but effective instructions for optimal communication between horse and rider. Combining an ergonomically formed curved 16mm Sensogan mouthpiece with the same angled center joint found in KK Ultra bits, this bit lies perfectly in the mouth. The result is soft and even pressure for maximum bit acceptance. 70mm stainless steel rings. Herm Sprenger Model# 40424 Price includes Free Shipping! Bit comes in box from Manufacturer.
