Loose Ring single jointed Rubber bit

Expert's Opinion: The Sprenger two-ring single-break rubber bit is a soft bit that offers a simple contact. Single-ring bits transmit the rider's aids on the edges of the tongue, and on the bars. When giving a rein action, the bit forms a V and exerts this pressure. This can be described as a "nutcracker" action. Single snaffle bits are not recommended for horses with a flat palate or small mouth cavity. They are best used on horses with a hollow palate and no sensitive bars or tongue. 

Loose rings transmit rein tension to the tongue and lower jaw without leverage on the nape of the neck. Loose rings provide less direct contact, which can help compensate for the rider's unstable and inexperienced hands. The horse also has the opportunity to lift the bit slightly with its tongue, which avoids strong tension on the reins in the short term. Thanks to their mobility, they are also slightly more relaxed. Loose rings are suitable for horses of all disciplines, at various levels of horse training, from young to old.
