Neue Schule TURTLE TACTIO FLEX T16mm, BEVAL 55 mm ring

Specifically engineered to accommodate the larger or sensitive tongue. Often negates the need to shut the mouth. The Beval ring gives rein and cheek-piece attachment options in a neat package but whatever option you choose the mouthpiece remains in constant relative alignment to the tongue. The flattened underside of the cannons with their anatomy-inspired recesses are held parallel to the tongue whatever riding activity you enjoy and for whatever rein tension you employ.
