A common problem is that horses become too strong, for example, on the jumping course, and the rider needs to switch to a stronger bit, which, in turn, causes the horse to lose its willingness to cooperate. With this in mind, Stübben has developed a bit that combines the ability to have extra control while maintaining the horse's willingness to cooperate!
As long as the horse moves relaxed to the rider's aids, the bit lies softly and comfortably in the mouth, contributing to the horse's suppleness. However, if the horse doesn't listen and instead pulls, the bit locks itself like a straight bit, motivating the horse to return to the milder state.
This bit also works excellently in everyday work as it is a milder bit that is ergonomically designed and comfortable for the horse.
