Bombers ST Hackamore  

The ST Hackamore applies mostly nose pressure through the rubber covered noseband, with virtually no poll pressure due to the noseband not being fixed.

The position of the noseband can be adjusted by moving the stopper below the noseband.  The curb pressure, while there, is fairly light and the backstrap can be adjusted to regulate how fast the action on the nose comes into effect.

Care must be taken to set the noseband so that it sits on the bony part of the nose, and not on the soft cartilage.

HACKAMORES VS BITS
If all bits have failed or the horse has a problem with the conformation of the mouth a hackamore would be recommended for intermediate riders and above. Correct fitting of all hackamores is crucial to avoid damage to the delicate nasal bones or blocking of the nasal passages. The Hackamore is best suited to more experienced riders as the feel is very different from a bit. Always bear in mind our philosophy that more pressure can result in more resistance. 

The Bombers Hackamore ST is a popular mechanical hackamore with a specific, fairly mild action. Here’s a compact, practical breakdown:

Key features

• Primary nose pressure — the rubber-covered noseband applies most of the pressure to the nose rather than the mouth. 

• Very little poll pressure — the noseband is not fixed, so poll-lifting action is minimal compared with many curb-style hackamores. 

• Adjustable noseband position — you can move the stopper below the noseband to change where it sits on the nose. 

• Light curb/backstrap action — there is some curb effect; the backstrap can be adjusted to change how quickly the nose action comes into effect. 

• Rubber-covered noseband — softer contact than bare chain/metal; intended to be kinder to the nose. 

When to use it:

• Horses that dislike or can’t tolerate a bit (mouth pain, dental issues, very mouth-sensitive horses). Many riders switch to hackamore designs when a bit aggravates the horse. 

• Horses that evade poll pressure — if you want steering/stop that doesn’t rely on lifting the poll. 

• Disciplines — commonly used in jumping / showjumping and general schooling when a non-bit option is needed; retailers list it under jumping bits/hackamores. 

• As a training tool — when used correctly it can be an alternative to address specific issues (resistance to a bit, leaning, seeking heavy contact). Use it as part of a considered training plan, not as a first resort.

Fitting & safety notes (must-read)

• Fit on the bony part of the nose only — don’t place the noseband on the soft cartilage below; incorrect fit causes pain and injury. 

• Adjust the backstrap carefully — changing it alters how quickly the nose pressure comes on; small changes have noticeable effects. 

• Still a piece of tack with leverage — “no poll pressure” doesn’t mean “no force.” Hackamores can injure if used improperly or on unsuitable horses. Treat it with the same respect you’d give any leverage bit. 

• Not a fix for poor riding or conditioning — if a horse pulls, is unbalanced, or lacks training, a hackamore can make things worse unless the underlying issues are addressed.

Quick checklist before trying one

1. Check noseband position — sits on hard nasal bone, not soft cartilage. 

2. Start with a soft backstrap setting (slower action) and ride lightly to assess reaction. 

3. Use short, careful sessions and evaluate changes in breathing, head carriage, and responsiveness. 

4. Consult your trainer/coach (or your vet/dentist if mouth pain is suspected) before switching permanently.
