Horse Spanish Curb Bit | Black Oxide Butterfly Cheekpiece & Single Joint Mouthpiece | BI-0057

BI-0057 Premium Spanish Curb Bit | Black Oxide Butterfly Cheekpiece & Single Joint Mouthpiece

The BI-0057 is a striking Spanish/Iberian curb bit featuring classic X-shaped (butterfly) cheekpieces with S-hook upper headstall attachments, a single-jointed mouthpiece, and loose lower rein rings — all finished in a bold black oxide coating. The butterfly cheekpiece provides a stable, non-rotating contact while the single-jointed mouthpiece delivers a clear, direct V-shape rein action on the bars, tongue, and corners — a more direct signal than the wave mullen of the BI-0060/BI-0061, making this an excellent choice for horses that respond well to a jointed mouthpiece in a classical Iberian cheek configuration.

Key Features

• Black oxide finish — a bold, dark coating that gives this classical Spanish bit a striking modern aesthetic; durable and resistant to corrosion with regular care
• X-shaped (butterfly) cheekpieces — a classic Iberian design that provides a stable, fixed contact; the broad cheek prevents the bit from rotating in the mouth and delivers clear, direct lateral signals
• S-hook upper headstall attachments — traditional Spanish-style S-hooks for clean, secure headstall connection; a distinctive feature of classical Iberian bridle hardware
• Single-jointed mouthpiece — creates a V-shape action on the bars, tongue, and corners when rein pressure is applied; a direct, responsive rein signal familiar to horses trained in snaffle work
• Loose lower rein rings — free-moving rings allow a degree of mouthpiece movement, softening the rein contact and encouraging the horse to mouth the bit

How to Use

Use with a correctly fitted curb strap or chain. The butterfly cheekpiece and single-jointed mouthpiece make this an excellent choice for horses that are well-schooled and respond to a direct, jointed rein signal within a classical Iberian cheek configuration. The S-hook headstall attachment is traditional to Iberian bridle fitting — ensure the hooks are correctly oriented for secure attachment.

Ideal For

Advanced horses in classical dressage, working equitation, Iberian disciplines, and traditional Spanish and Portuguese horsemanship. A refined bit for riders who want the elegance of classical Iberian design with a direct single-jointed mouthpiece and a bold black finish.

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