The eggbut is a basic bit. It is generally a soft bit. The rings cannot move separately and therefore the help of the hand works a bit more directly. Because the rings cannot move separately from the nozzle, bit rings are not necessary. The bit is fairly stable in the mouth. The eggbut is recommended for young horses and for a rider with a normal hand.
Properties of the straight mouthpiece:
A straight mouthpiece often works sharper than a single or double-mouthed mouthpiece. The shape of the mouthpiece determines where the pressure will lie in the mouth. A straight mouthpiece with tongue / port gives more pressure on the layers and keeps the tongue free. The straighter and thicker the mouthpiece, the more pressure on the tongue.
