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 only 1 ½" 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.
Independent Side Movement
Stainless Steel Mouthpiece
Notes: 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.
The Kimberwick is a “D” shaped stainless steel ring with a purchase for the headstall and two attachment options for a single pair of reins: the direct (snaffle) and the indirect (curb) positions. Comes with curb chain. Like the Pelham, the purchase creates a fixed cheek so the bit is held in the correct position. The rider can choose the direct (snaffle) position or indirect (Curb) position for rein attachment. The Indirect Rein position adds very little to mild leverage. Designed to be used with only one pair of reins.
Action: Snaffle position is Direct rein action. Curb position is Indirect rein action.
Size: 4" “D” shaped ring with purchase
Degree of Leverage: Very little to mild leverage when the lower rein hook is used.
