The blue sweet iron rollers on this Bombers Cherry Roller Full Cheek Snaffle Bit are constructed tightly, so there is no chance of pinching. The rollers promote relaxation in the lower jaw by encouraging the horse to mouth and play with the bit, thus reducing the likelihood of him grabbing hold of the bit or leaning on it.
The blue sweet iron oxidises easily, creating a warm and sweet taste in the horse's mouth, which encourages salivation, gentle mouthing and acceptance of the bit.
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, therefore encouraging 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. 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.
