The Double Jointed Novocontact Sensogan D-Ring Eggbutt Ø65 mm from Sprenger is a double jointed eggbutt bit with D-shaped rings and modern novocontact geometry. The mouthpiece is ergonomically designed and creates an oval shape that provides an enlarged contact surface on the tongue during even rein contact. With increased rein aids, the mouthpiece rotates forward, reducing the contact surface and enabling more precise and effective communication through direct pressure transfer to the tongue and lower jaw.
The double jointed construction combined with the fixed D-rings provides a slight limiting effect and helps the bit remain stable in the mouth with clear lateral contact. The design also helps protect the horse’s sensitive lip corners. This model allows direct transmission of rein aids and is designed for horses that may occasionally become strong in the hand but are too sensitive for more severe bits. The bit has a thickness of 14 mm and a ring diameter of 65 mm.
The bit is made from Sensogan, an alloy of copper, manganese, and zinc. The manganese hardens the copper without affecting the natural oxidation process, making it possible to achieve the same oxidation behaviour as Aurigan, despite a lower copper content.
Sensogan bits should be thoroughly cleaned with water after each use and then dried. As the material contains copper, oxidation may cause the bit to darken and lose its shine over time. If necessary, Sprenger Diamond Paste can be used for cleaning and maintenance.
