The Eggbutt Dynamic RS Sensogan D-Ring Ø65 mm from Sprenger is a bit with fixed D-shaped rings and an ergonomically designed Sensogan mouthpiece. The centre joint is angled 45° forward, which is a characteristic feature of the Dynamic RS series and contributes to more even pressure distribution across the tongue. The construction is designed to lie anatomically correctly between the tongue and the palate.
The fixed D-rings allow direct pressure transfer to the tongue and lower jaw as well as light pressure on the poll. The design helps the bit lie stable in the mouth, is gentle on the corners of the mouth and can provide a lateral framing effect. The mouthpiece is available in both 14 mm and 16 mm thickness. The ring diameter is 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 and allows the same oxidation behaviour as Aurigan, despite a lower copper content. Sensogan is a high-quality and toxicologically tested bit material.
Sensogan bits should be cleaned thoroughly with water after each use and then dried. If necessary, Sprenger Diamond Paste can be used for cleaning and maintenance.
