This is a popular bit in showjumping. It offers a mild gag action, while the curved mouthpiece and ring design gives clear turning aids. The top (bridle cheek) rings are very cleverly angled in order to avoid excessive cheek pressure.
This model has a centre lozenge that sits flat on the tongue with rein pressure, and also features a gold finish mouthpiece, which encourages acceptance.
Always recommend bit guards with a Universal or 3-Ring Gag as the cheeks can pinch when rein pressure applied.
