Key Features As with the Pelham, the action of the Kimblewick is dependent upon the position of the riders hands. The rein slides on the Dee shaped bit ring. If the hands are lowered prior to pressure being applied to the reins, the rein will slide about an inch and the bit will assume roughly a 45° angle in the mouth. Causing the mouthpiece to act in a downward and backward motion on the lower jaw, this is complemented by a downward pressure on the poll, giving the bit a lowering action. There are 3 rein settings which increase or decrease the pressure. The Happy Tongue is a solid mouthpiece uniquely ported to give maximum tongue relief. The standard Happy Tongue is curved to be softer on the bars and slow in applying tongue pressure. Cheekpiece The cheekpiece is available in 2 sizes, standard and a slightly smaller model for a pony. The standard size Kimblewick is available with a shorter purchase, the Kimblewick Lite. Supplied with a nylon back strap. Mouthpiece This is by far our most successful design - we recommend for all young horses and those that show tongue sensitive signs. The 4 available ports have been scaled according to each width. This ensures accurate fitting over the bars and eliminates the rocking movement which occurs when the port is too wide.The Happy Tongue is also available as a straight mouthpiece which is slightly stronger.
