The Barrie is a severe bit due to the centre links of the two pieces being offset giving it a double nutcracker action, which creates more tongue and bar pressure.
Excessive bit causing severe pinching of the tongue and bars. Bomber would prefer to offer a softer alternative where possible; such as the Buster Roller, which is recommended for strong older horses or those with a low head carriage.
The Corkscrew mouthpiece is grooved to offer extra control over strong horses. The groove in the mouthpiece causes edges that result in pressure points in the horse’s mouth. The edges amplify pressure on the mouth, especially the bars and tongue, and also act on the lips. This offers the rider more control than a smooth mouthpiece, and can help to prevent the horse from leaning.”
The Barrie creates pressure points on the tongue due to the links concentrating pressure on a small surface areas. Pressure descends onto the bars and due to the mouthpiece being a single break, it will create a squeeze on the bars – this squeeze on the bars is less than the squeeze created by a single jointed mouthpiece but more than most double jointed mouthpieces due to the Corkscrew. The Barrie creates two different tongue pressure points which are both concentrated on small surface areas. The two separate branches will also create a lot of squeeze on the bars due to their individual nutcracker actions. The Sweet Iron material was chosen as a metal option as it oxidizes. Oxidization encourages salivation and acceptance of the mouthpiece. The single break, Barrie, is a broken mouthpiece and will take the shape of the horses mouth.
