Myler® Stainless Steel Medium Baucher, MB 33 Low Medium Wide Ported Barrel, Level 3. For English disciplines but not legal in dressage as port exceeds 30mm in height.

The MB 33 is the mildest Myler mouthpiece in terms of tongue pressure. The generously wide port allows room for the tongue to pass almost completely under the bit. Because this mouthpiece does not rotate on to the tongue and the port is wide, it applies little to no tongue pressure, working primarily off the lips and bars. The port on this mouthpiece is 1 1/2" high, so it will apply little to no palate pressure. Because the MB 33 offers such a high degree of tongue relief, the horse that goes well in this mouthpiece has a trustworthy and consistent disposition, and is trained to work off the leg and seat as well as the hands.

Key features:

• Independent Side Movement™.
• Stainless steel mouthpiece.
• Curved mouthpiece.
• Copper inlay.
• Not dressage legal (port over 30mm tall).

Notes:

• For the USEF dressage legal version of the MB 33, see the MB 33WL.
• For a slight increase in tongue pressure, see the MB 43LP or MB 43MP.
• For same tongue relief without Independent Side Movement, see the MB 16 (Western only).
• For the same tongue relief and Independent Side Movement, but with a slight degree of collapse, see the MB 05.
• For more generous tongue relief, see the MB 16PB.

Also known as a “hanging cheek” because the bridle attaches at the purchase. The fixed cheek keeps the bit suspended in the horse’s mouth and prevents it from sliding around in the bridle, giving the rider more control over the mouthpiece than a traditional loose ring. However, the reins remain free to slide. When engaged, the reins will pull back on the cheekpiece and mouthpiece, as well as rotate the purchase forward slightly, creating some poll pressure. Even though it has a fixed cheek, the Baucher is still considered a direct rein action cheekpiece because there is no leverage or curb action.

Action: Direct.
