Horse Western Curb Bit | Stainless Steel Mullen Mouth & Long Straight Shanks | BI-0045

BI-0045 Premium Western Curb Bit with Mullen Mouth Mouthpiece

The BI-0045 is a classic western curb bit featuring a smooth mullen (straight bar) mouthpiece and long straight shanks — all in polished stainless steel. The unjointed mullen mouthpiece distributes pressure evenly across the bars and tongue without any nutcracker action, making it one of the gentlest mouthpiece options in the western curb range. The long straight shanks provide a clear leverage action on the poll and chin groove, encouraging collection and a soft, responsive contact.

Key Features

• Mullen (straight bar) mouthpiece — smooth, gently curved unjointed bar distributes pressure evenly across the bars and tongue; no nutcracker action, making it comfortable for horses with a sensitive mouth
• Long straight shanks — provide a definite leverage action on the poll, bars, and chin groove; the longer the shank, the more leverage and the slower the signal — rewarding horses that respond to light rein pressure
• Small upper headstall rings — for clean, direct headstall attachment
• Small lower rein rings — for precise rein attachment at the base of the shank
• Full stainless steel construction — rust-resistant, hygienic, and built for long-term use in western disciplines

How to Use

Always use with a properly fitted curb strap or chain. The mullen mouthpiece and long shanks make this bit best suited to horses that are well-schooled in neck reining and respond to light, subtle rein cues. Use with soft, following hands — the leverage action amplifies pressure, so minimal movement produces a clear response.

Ideal For

Well-trained western horses in reining, western pleasure, trail riding, and ranch work. The mild mullen mouthpiece makes this an excellent choice for horses with a sensitive mouth that need a leverage bit for collection and refinement.

Size Guide: Measure your horse's mouth width from corner to corner and add 0.5 cm for the ideal fit.
