a central core which determine the flexibility: here, the flexibility + allows you to stimulate the same mechanoreceptors as a double-jointed bit.
the intermediate core which give the ergonomics: the morphology of the horse’s mouth is respected with a better distribution of the pressure points.
the cover layer will provide damping: the mouthpiece “strong” provides reactive damping. The information transmitted to your horse is less attenuated than with other damping. The horse’s reaction will therefore be immediate.
