Is this trotting bit allowed in other riding disciplines?

Hi! Great questions 🥰

The fullcheek arms at the sides act as a kind of fullcheek. Their job is to help frame, steady and nudge the horse sideways. They also spread some of the pressure outside the mouth, which many horses appreciate.

The mouthpiece is single-jointed. That makes it slightly harsher than a double-jointed bit, because there is only one break point. On a rein aid, the bit folds into a V in the mouth and can rise up and press into the palate. This is the nutcracker effect, and it gets worse if the bit is too long. Fitting a single-jointed bit correctly therefore matters a great deal. Whether a horse goes better in a single-jointed or a double-jointed bit is individual. Single-jointed bits tend to suit horses with a high palate, and horses with excess mucous membrane over the bars. 🤗

Yes, you can absolutely use this bit for riding. I would swap it for a single-jointed bit with a lock, a double-jointed bit or a mullen mouth, though, especially for endurance. The bit stays in the mouth for far longer than usual on an endurance ride, so the risk of pressure injuries goes up.

Under the Swedish competition rules (TR), bitting in endurance is open, as long as you can control the horse and the bit does not harm it. So yes, you are allowed to ride with it.
