Stainless Steel 3 3/4" Dee with Stainless Steel French Link Snaffle (MB 10) Copper Inlay Mouth. About the mouthpiece: the 10 mouthpiece is a more comfortable Myler version of the traditional French link mouthpiece. The traditional link typically measures 1 ¾" long and ½" wide (at the narrowest point); in comparison, the Myler French link measures 1 ¼" long and ⅜" wide. The smaller link allows the tongue more room in the mouth and minimizes interference with the palate. Although it lacks the benefits of a “true” Myler mouthpiece, the 10 is curved so the bars of the bit wrap the horse’s bar and lips instead of pinching. Finally, the Myler French link has a flatter contour than a traditional French link, also allowing more room for the tongue. It disperses pressure over the tongue similarly to the 02, but does not offer the Independent Side Movement of a true Myler mouthpiece. The 10 is popular with riders who are more comfortable with a traditional design, but we recommend the 01, 02, or 03 to get the full benefit of Myler features. For more tongue relief, step up to the 04. From The Level Best for Your Horse by Dale, Ron and Bob Myler. ©Toklat Originals, Inc.
