The Medium Flex + mouthpiece consists of 3 layers:
a central core offering the flexibility of the mouthpiece: flexibility + stimulate the same mechanoreceptors as a double-jointed bit.
the intermediate core giving the mouthpiece ergonomics: the pressure points are well distributed, the morphology of the horse’s mouth is respected.
the cover layer providing damping: the “Medium” mouthpiece is less damping than a “Soft” and more damping than a “Strong” mouthpiece. The information transmitted from the rider’s hands to the horse’s mouth is partially absorbed. This is an intermediate damping.
