The Sprenger KK ultra snaffle has been designed after extensive research to provide the optimum shape horse bits to fit the anatomy of the horses mouth. The KK ultra snaffle has a mouthpiece made from the revolutionary patented material Aurigan, which works like no other metal. Aurigan is a copper based material that oxidises to produce a pleasant and distinctive taste that horses love, and encourages a soft relaxed jaw, wet mouth and quick acceptance of this Sprenger bit. The University of Hanover has proven through a long term study that Aurigan, containing silicon and being nickle free, combines the oxidation advantages of copper but with maximum strength and durability. The ergonomically designed mouthpiece of the Sprenger KK ultra snaffle bit is shaped to lie unobtrusively in the horses mouth resulting in a soft and even pressure on the entire tongue area, encouraging the horse to accept the contact willingly and in a relaxed manor. The angled lozenge in the centre of this Sprenger bit is tilted forward by 45 degrees for comfort, and utilises the exceptional sensitivity of the tongue. KK ultra bits are available in 4 thicknesses, 14mm, 16mm, 18mm and 21mm. The 14mm is a good choice for stronger horses or those with a small mouth or big tongue. Sprenger have developed a bit that provides the rider with a kind, effective and consistent communication chanel with their horse.
