The 2421 Easy Control Loose Ring Snaffle Soft-Roll double jointed transitions between a flexible snaffle and a straight-bar bit depending on rein pressure. Under light contact it behaves like a gentle snaffle, but when the horse pushes forward on both reins, it transforms into a bar-bit. Its double-jointed mouthpiece distributes pressure evenly across tongue and bars, while the soft copper roll in the center stimulates salivation and encourages acceptance.
