Almost every horse owner asks themselves this question. Although at first glance the difference seems small – after all, it is just one joint more – in reality both these bits work completely differently in the mouth.
A wrong choice can lead to escaping from contact, throwing up the head and even pain. In this article we explain the mechanics of both solutions so you can make an informed decision.
1. The single-jointed bit – a classic with a “catch”
The single-jointed bit consists of two parts joined in the middle. For years it was considered the gentlest, but modern knowledge of anatomy sheds new light on it.
- How does it work? During rein action the bit folds into a “V” shape.
- The “nutcracker effect”: This is the biggest threat. With strong hand action, the middle joint can rise high and dig into the horse’s palate, while at the same time squeezing the edges of the lower jaw.
- For whom? For horses with a high palate and a thick tongue, which need a clear signal on the edges of the lower jaw.
- Important: At Balotade we use anatomical profiling even in single-jointed bits, which significantly reduces the risk of pressure on the palate.
2. The double-jointed bit – comfort and precision
It has two joints and a middle element (link). Thanks to this the bit fits the natural shape of the tongue better.
- How does it work? It arranges itself in the mouth into the shape of a gentle arc (the letter “U”).
- Pressure distribution: The pressure is distributed evenly over the tongue and the edges of the lower jaw, and the middle link lies flat on the tongue, not touching the palate.
- For whom? For most horses, especially sensitive ones, which do not accept the point pressure of a single-jointed bit.
- Advantage: It makes it easier to relax the jaw and encourages chewing.
A comparison in a nutshell
| Feature | Single-jointed | Double-jointed |
| Shape in the mouth | Letter “V” | Letter “U” |
| Main point of pressure | Edges of the jaw + palate | Tongue + edges of the jaw |
| Action | Direct, can be point pressure | Diffused, usually gentler |
| Risk of pain | Possible palate pressure | Possible excessive tongue pressure |
🔥 Find the ideal bit at Balotade
Whether you choose a single- or double-jointed bit, at Balotade we focus on an anatomical shape that respects the sensitive interior of your horse’s mouth.
How to check what your horse prefers?
The choice depends on the structure of the mouth (the amount of room for the tongue and the height of the palate):
- Observe the reaction to contact: If the horse throws up its head when the reins are taken up on a single-jointed bit, the joint is probably digging into its palate – try the double version.
- Tongue sensitivity: If the horse becomes “dead” on a double-jointed bit or puts its tongue over it, this may mean that the pressure on the tongue is too great for it – then it is worth returning to an anatomical single-jointed bit.
- Tongue thickness: Horses with a very thick tongue often have little room in the mouth – for them a double joint (with the additional link) may take up too much space.
Summary
There is no single universal answer, but statistics show that most horses work better on double-jointed bits. The key, however, is not only the number of joints, but above all the quality of workmanship and the anatomical curve that you will find in every Balotade product.
