The mouthpiece may slide on the full, loose ring, so that it rests on the most comfortable position for the horse, rather than fixed. The horse may relax its mouth and chew the bit. All bits are available in middle soft (green) and soft (red) hardness.
The mouthpiece has a hexagonal shape, with large side washers which prevent pinching of the bit on the labial commissures and to prevent the ingestion of air. The side supports are unique in the market. They are made from bestSwedish steel.
