Dr. Bristol: A double-jointed mouthpiece, similar to the French link, yet more severe. That’s because the centerpiece of the Dr. Bristol design is rectangular, thinner, and includes angular edges.
- The centerpiece is slightly offset from the other sections of the mouthpiece.
- When the Dr. Bristol bit rotates in a horse’s mouth, the edges of the centerpiece exert pressure on the horse’s tongue and other sensitive parts of its mouth.
- A popular bit with jumpers, because more control is available when needed.
