Double-Jointed Bits: A Precise and Comfortable Mouthpiece

The double-jointed bit is now one of the most widely used bits in equestrian sports. Thanks to its mouthpiece consisting of two joints and a central link, it distributes pressure more evenly within the horse's mouth than a single-jointed bit.

Popular across many disciplines, the double-jointed bit promotes stable, precise and comfortable contact. It is suitable for a wide variety of horses, particularly those with a thick tongue, low palate or greater sensitivity to the pressure exerted by certain bits.

How does a double-jointed bit work?

The mouthpiece consists of three sections:

• a right-hand section,
• a left-hand section,
• a central link connecting the two sections.

When the rider applies rein pressure, pressure is distributed across:

• the bars,
• the tongue,
• the corners of the mouth.

Thanks to its two joints, the bit follows the shape of the horse's mouth more closely and reduces the nutcracker action that a single-jointed bit can produce in some horses.

Why choose a double-jointed bit?

More even pressure distribution

The two joints allow the bit to adapt more easily to the anatomy of the horse's mouth.

This design is often appreciated for:

• sensitive horses,
• horses with limited space in the mouth,
• horses with a thick tongue,
• horses that find certain single-jointed bits difficult to accept.

More consistent contact

The double-jointed bit follows the movements of the horse's mouth more closely.

It encourages:

• relaxation,
• stable contact,
• better acceptance of the bit,
• more precise communication between horse and rider.

A versatile mouthpiece

The double-jointed bit is used:

• in dressage,
• in show jumping,
• in eventing,
• for leisure riding,
• for everyday training.

Its comfort makes it a popular choice for riders and horses at all levels.

Different types of double-jointed bits

Double-jointed loose ring bit

The most mobile design.

Benefits:

• encourages relaxation,
• encourages the horse to mouth the bit,
• provides a softer contact.

Double-jointed eggbutt bit

The fixed rings provide greater stability.

Particularly suitable for:

• sensitive horses,
• horses requiring consistent contact,
• everyday training.

Double-jointed D-ring bit

Its fixed D-shaped cheeks provide greater lateral guidance.

Ideal for:

• young horses,
• horses requiring additional guidance,
• basic training.

Double-jointed full cheek bit

The long side cheeks provide increased lateral guidance.

Often used for:

• backing young horses,
• young horses,
• developing steering and direction.

Double-jointed Baucher bit

Its upper cheek attachment provides greater stability in the horse's mouth.

Valued for:

• its stable contact,
• its precision,
• its discreet design.

Double-jointed Pessoa bit

With several rein attachment options, it allows the action of the bit to be adjusted according to the chosen setting.

Mainly used:

• in show jumping,
• for horses requiring greater control.

Different types of central link

Not all double-jointed bits feature the same type of central link.

Common designs include:

Round lozenge
The most common design.

Lozenge
More elongated in shape, it can provide improved pressure distribution in some horses.

Anatomical mouthpiece
Designed to follow the natural shape of the horse's mouth more closely.

The choice mainly depends on the horse's mouth conformation and individual preferences.

How to choose a double-jointed bit

According to your horse's sensitivity

• sensitive horse → eggbutt, Baucher or anatomical mouthpiece
• horse requiring greater mobility → loose ring
• young horse → D-ring or full cheek

According to the horse's mouth conformation

The bit should be suited to:

• the width of the mouth,
• the thickness of the tongue,
• the space available between the tongue and palate,
• the sensitivity of the bars.

Although double-jointed bits suit many horses, every horse has individual preferences.

According to your training goals

• everyday training → loose ring or eggbutt
• dressage → eggbutt, Baucher or anatomical mouthpiece
• developing steering → D-ring or full cheek
• show jumping → eggbutt, Pessoa or Baucher depending on the horse's needs

Available materials

Double-jointed bits are available in a wide range of materials:

• stainless steel bits,
• copper bits,
• bits made from alloys designed to encourage salivation,
• sweet iron bits,
• resin bits,
• rubber bits.

Each material influences the feel of the contact, the temperature of the bit and how readily the horse accepts the mouthpiece.
