Frequently Asked Questions:

Q: How do I know if my horse is ready for a Level 3 Myler bit?
A: The MB 12 is designed for "finished" horses—those that are highly trained, relaxed, and consistently respond to light aids. If your horse is already soft in the mouth and requires only subtle reminders to maintain collection and frame, this Level 3 design provides the maximum comfort they deserve.

Q: How should I measure for the correct fit with the Myler sizing rule?
A: Due to the forward-curved design, a Myler bit should fit slightly wider than a traditional straight bit. You should see approximately 1/8" to 1/4" of the mouthpiece visible on each side of the horse's lips to prevent pinching and ensure the port sits correctly over the tongue.
