This bit is designed to provide added tongue stimulation, thanks to its double-jointed mouthpiece that eliminates the nutcracker effect and offers a more comfortable fit for your horse. The central roller also encourages tongue activity, promoting relaxation and focus.

The King Dee cheekpieces provide lateral guidance and a steady, balanced feel, making it ideal for training and daily use.
