This bit is used for strong horses when maximum leverage and steering is required. Nelson cheeks are designed to reinforce the turning aid and reduce the chance of rubbing. The two rein option will allow the rider to have varying degrees of control and be able to differentiate between the snaffle rein and the running cheek rein that provides poll pressure. The BLU Sweet Iron mouthpiece creates a warm, sweet taste in the horse's mouth. This material is known to encourage salivation and acceptance of the bit. The Waterford mouthpiece is made up of rounded links that bend easily to fit the horse's mouth. This helps to evenly distribute pressure. It also moves in different directions which makes it hard for the horse to hold onto the bit.
