Sprenger's Dynamic RS range of bits have mouthpieces that are ergonomically designed, to suit the shape of the horse's mouth. The curved mouthpiece sits comfortably over the horse's tongue, with the central lozenge angled so as to be flat and smooth when the reins are taken up. This results in an even level of bit pressure across the horse's tongue and lips and makes for a mild, consistent contact.
The Universal cheekpieces provide you with a range of options, whether with one rein or two, particularly useful for a horse that can be strong in some circumstances. Combined with the Sensogan alloy mouthpiece, this is a really versatile bit that provides control but with respect for the horse's comfort.
