Bucephalus: The Mors de Bocéphale Pro is a soft and flexible bit. The reins are attached to the D-rings of the bit with two strong rubber pieces. This creates a flexible connection between the rider's hand and the horse's mouth, promoting the engagement of the hindquarters in the reins. The pressure transmitted through the horse's mouth is reduced, which encourages forward movement, rhythm, and a smoother contact. This naturally promotes elasticity in the horses' movement and their willingness to collect.
