The Venice fixed ring bit has a double-jointed mouthpiece, designed to sit comfortably in your horse's mouth.
The link in the centre of the bit relieves that 'nutcracker' effect on the mouth. The 'nutcracker' effect is most common in single-jointed bits that may push down on the horse's tongue when both reins are pulled simultaneously.
The Venice fixed ring style keeps the bit steady in the horse's mouth, and it's made with titanium, a high-strength metal with no taste.
