The Sprenger flagship KK ultra series of bits completely revolutionised the concept of snaffle bits, using an anatomically shaped lozenge mouthpiece and the patented aurigan metal alloy.  Since the KK Ultra range, Sprenger have continued to innovate with the launch of the Dynamic RS range, WH Ultra range and most recently the Novocontact collection.

Their unique aurigan mouthpiece has also been subject to refinements with the new improved sensogan bit material with adjusted levels of copper, manganese and zinc in the mouthpiece. Sensogan focuses on the taste and salivation aspect of the bit, giving even more connection to the horse, with a slightly reduced copper content to the original aurigan material.
