All three are double jointed: two joints with a centre piece between them. Compared with a single-jointed snaffle, there’s no nutcracker squeezing up into the palate, and the mouthpiece wraps around the tongue more evenly. The difference is entirely in that centre piece.
The French link has a short, flat plate in the middle. When you take a contact the plate lies flat on the tongue, so the pressure is even and soft. It’s a sound everyday bit and a common step on from a single-jointed snaffle.
Try the French Link Loose Ring Snaffle or the steadier French Link Eggbutt.
This is the one people get wrong. The Dr Bristol’s plate is longer and set at an angle to the rest of the mouthpiece, so when you take a contact its edge presses into the tongue. The result is a sharper, more defined pressure. It’s a stronger bit, designed for when you need extra help slowing down or stopping, and it isn’t a gentler cousin of the French link.
It has its place on a horse that gets strong across country, but it won’t encourage a soft, true contact. It’s not permitted in dressage either. See the DB Dr Bristol, or the Trust Full Cheek Dr Bristol for more steering help.
A lozenge is a small, rounded centre piece with no flat faces or edges. It sits quietly on the tongue and moves smoothly with the mouth, which is why it has become the default for many modern snaffles.
Some designs go further and angle the whole mouthpiece so the lozenge meets the tongue more naturally, like the Neue Schule Tranz Angled Lozenge Loose Ring. For a straightforward version, the Loose Ring Snaffle with Lozenge is hard to beat on price. For a horse that plays with his tongue, the curved Neue Schule Verbindend is designed to discourage tongue evasions, and it’s dressage legal.
| Centre piece | Feel on the tongue | Typical use | |
|---|---|---|---|
| French link | Short flat plate | Even, mild | Everyday flatwork and hacking |
| Dr Bristol | Longer plate set at an angle | Sharper, edge pressure | Extra brakes on a strong horse |
| Lozenge | Small rounded piece | Smooth, quiet | Most horses, most jobs |
Start with a lozenge or a French link. Both suit most horses, and the choice between them is often down to the individual horse’s preference. Treat the Dr Bristol as a tool for a particular job, not a default. If your horse only goes kindly in a Dr Bristol, it’s worth asking why, and our bit fit checklist is a good place to start.
The shape of the centre piece is easy to overlook when you’re browsing snaffles by cheek, so look closely at the product photos.
The quickest way to settle the choice is to ride in each one. The lozenge bits above, the Verbindend and the Trust Dr Bristol can all be borrowed on a 30-day Bit Bank trial. If you’d like help reading what your horse is telling you, call our Bitting Specialists on 01405 861800, option 3.
