Myler Level 3 Medium English Dee Bit with Hooks - Sweet Iron Mouthpiece 33

Give Your Finished Horse the Ultimate Tongue Relief

The Myler Medium English Dee with Hooks and the MB 33 mouthpiece is the gold standard for riders who have put in the work and have a horse that is ready for maximum comfort. If your horse is already responsive to your seat and legs but tends to get fussy or busy in the mouth with traditional bits, the Level 3 relief provided by this Myler design is a game-changer for your communication.

This bit is engineered with a 1 ½" wide port that allows for total tongue freedom, meaning your horse can swallow easily and stay relaxed through the poll and jaw. From our barn to yours, we know that a relaxed horse is a focused horse, and this bit is built to help you achieve that soft, consistent connection in the ring or on the trail.

Key Benefits for You and Your Horse

• Maximum Tongue Relief is achieved through the Level 3 MB 33 mouthpiece, featuring a wide 1 ½" port that allows for free swallowing and eliminates tongue pressure for finished horses.
• Enhanced Lateral Control is provided by the 3 ⅜" Medium English Dee cheekpieces, which offer a stable feel and prevent the bit from being pulled through the mouth during turns.
• Stability and Poll Relief are made possible by the integrated hooks, which allow for an indirect action that stabilizes the bit and provides a touch of poll pressure when needed.
• Independent Side Movement allows you to lift one shoulder at a time, making it easier to refine your lateral work and help your horse stay balanced through corners.
• Ergonomic Curved Design wraps comfortably around the bars of the mouth, avoiding the harsh nutcracker effect and encouraging a softer feel in the hand.

Frequently Asked Questions

Q: How should I size this Myler bit for the best fit?

Myler bits follow the "Myler Gap" rule. Unlike traditional bits that should fit snugly against the lips, the Myler Med Eng Dee w/Hooks 33 should have about 1/8" to 1/4" of the mouthpiece visible on each side of the horse's mouth. Because of this curved design, these bits often fit about 1/8" larger than your standard bit size.

Q: Is this bit legal for Dressage competition?

While the MB 33 mouthpiece is often permitted in various disciplines, the addition of hooks (slots for the headstall and reins) makes this specific bit illegal for sanctioned Dressage. It is an excellent choice for Show Jumping, Eventing schooling, and Trail Riding where poll relief and stability are desired.

Q: What makes the Level 3 mouthpiece different from Level 1 or 2?

A Level 3 mouthpiece like the MB 33 provides the most tongue relief Myler offers. It is intended for horses that are considered "finished"—meaning they are trustworthy, consistent, and respond primarily to the rider's weight and leg cues rather than needing constant bit pressure.
