Short hackamore shanks

Short hackamore shanks: more direct, more moderate leverage

Short hackamore shanks have a direct influence on the mechanical action of a hackamore. By reducing the length of the leverage arm, they provide a more direct transmission of the rider's rein aids while limiting the amplification of pressure applied to the horse's nose, the curb chain beneath the jaw and the poll.

However, this does not mean that a hackamore fitted with short shanks is automatically "milder." Its overall performance always depends on the complete bridle setup as well as the quality and precision of the rider's hands.

What is the role of hackamore shanks?

The shanks form the leverage system of the hackamore. Their length determines the degree of mechanical advantage generated when rein pressure is applied. The longer the shanks, the greater the leverage effect. Conversely, short shanks reduce this mechanical advantage, generally resulting in a more immediate and direct response.

The sensations experienced by the horse nevertheless depend on many other factors, which is why two hackamores fitted with shanks of the same length can perform quite differently.

Shank length is only one part of the equation

The length of the shanks is only one aspect of a hackamore's overall function. Its final action results from the interaction between several components:

• the length of the shanks;
• the stiffness and construction of the noseband;
• the type of hackamore curb chain and its adjustment;
• the positioning of the hackamore on the horse's nose.

It is the combination of these factors that determines how pressure is distributed and how the hackamore ultimately performs.

Short hackamore shanks and competition regulations

In competition, the length of hackamore shanks is governed by the rules of individual equestrian federations and disciplines. Maximum permitted dimensions may apply, particularly in show jumping and eventing, to regulate the leverage effect of approved hackamores. As these regulations may change over time, it is advisable to consult the current rulebook for the relevant discipline before competing.
