A Kimberwick is a curb (leverage) bit. The further the reins slide down the Dee ring, the more leverage is applied. The curb chain or straps prevents the bit from rotating too far in the horse's mouth. When the reins are pulled back the bit applies pressure on the roof of the mouth, the chin and the poll. If there is a port, there may be pressure on the roof of the mouth. This is a bit commonly used in general riding and provides more aids to a horse that may be a strong puller or needs slight curb action to lower its head.
Available in 5" only.
Bits should be replaced regularly. If in doubt, replace it!
