Myler Black Steel Seven Shank SI Low Port Comfort Snaffle MB 04 - Test Ride Bit

A reliable transition bit for Level 2 horses, the Myler MB04 Low Port Comfort Seven Shank Curb Bit offers gentle tongue relief, mild leverage, and clear lateral cues. The MB04 sweet iron mouthpiece features a wide barrel and a low 1/4" port, encouraging relaxation and forward movement while still applying moderate bar and tongue pressure when rein aids are engaged. The signature Seven Shank design includes a mild curve and stylish dot accents, offering more leverage than a short shank but remaining smooth and balanced. Myler’s patented Independent Side Movement allows for isolated rein signals, helping improve headset and responsiveness in horses advancing in their training.
