Watch LessonBuster Roller Round Twist
The Buster Roller link is shortened which increases bar and tongue pressure making this mouthpiece sharper than conventional link bits. The increased pressure on the bar will lift the head and the roller will increase pressure on the tongue bringing the chin in. Best suited for a horse with a low head carriage and which leans on the bit.
The Round Twist creates more pressure points on the bars making it a stronger bit.
Bomber recommends this mouth piece as an alternative to the Barrie, it is kinder and achieves a similar result. Recommended for horses that are built downhill.
Functionality
The Buster Roller creates a direct pressure point on the tongue. The tongue pressure is direct and unforgiving, center component is a smooth roller that concentrates pressure on a small surface area. Pressure descends onto the bars and due to the mouthpiece being a double 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.
The twists in the mouthpiece will create pressure points on the tongue that descend onto the bars. These twists are milder than the square twist as the round twist has a more rounded surface area, though that surface area is very small.
The Buster Roller Round Twist is available in Sweet Iron. The Sweet Iron material was chosen as a metal option as it oxidizes. Oxidization encourages salivation and acceptance of the mouthpiece. The double break, Buster Roller, is a flexible mouthpiece and will take the shape of the horses mouth.
