This Elliptical Lozenge Full Cheek Snaffle from Bombers Bits has a 45mm lozenge, which is designed to help the horse to mouth the bit and comfortably relax his jaw. The double joints remove the nutcracker action, as the bit stays in a curved shape, following the contours of the horse's mouth. Therefore the bar and palette pressure associated with single-jointed bits is removed.
The blue sweet iron mouthpiece oxidises easily, warming up and creating a sweet taste. This encourages the horse to salivate and gently mouth the bit, accepting and softening to the contact.
Full cheeks can be useful for horses that are unsure of the bit, because the bit doesn't move around so much in the mouth as it would do with loose rings. The fixed nature of the mouthpiece can encourage the horse to stretch into the contact. The full cheeks also help to prevent pinching at the sides of the mouth.
The arms of the full cheeks assist with steering, as pressure is applied to the cheek when a turning aid is given. This can be useful for young horses, or schooling and training purposes. The cheeks also ensure that the mouthpiece remains in a central position and cannot slide through the horse's mouth.
Please note that the blue will fade with use.
