The ergonomically formed mouthpiece allows a rapid and balanced effect on the tounge, encouraging the horse to chew. In addition, this bit supports the contact to the corners of the mouth in a very effective way, keeping the horse on the bit. The mouthpiece is made of SENSOGAN, the material that activates the chewing activity of your horse. Dynamic RS bits encourage the horse to accept the bit more easily. In comparison to conventional single jointed bits Dynamic RS mouthpieces give even pressure on the entire tongue area. Dynamic RS bits represent a better contact between the horse and ride.
