Curb and Bradoon Bit Sizes
Curb and bradoon bits are available in the same standard sizes as most other bits are and are measured between the mouthpiece rings or cheeks, usually ranging in sizes from 3, 3.5, 4, 4 1/4, 4.5, 4 3/4, 5, 5 1/4, 5.5, 5 3/4 and 6 inches.
Uses Of Double Bridle Bits
Double bridles are used for showing and elementary dressage upwards. Double bridles can also be used for showjumping and cross country however it takes an experienced rider to successfully and correctly use two sets of horse reins.
Curb Bits Fitting Bits
The bits must fit correctly to enable the horse to successfully perform at their best. Each horse’s mouth is unique and the type of mouthpiece and cheeks are chosen must reflect the horse’s individual way of going.
The curb bit should sit a quarter to a half an inch lower in the mouth than the bradoon bit which sits in the corners of the mouth again just wrinkling the corners of the horse’s mouth, the curb chain is then fitted into the chin groove.
The curb chain acts when the pressure to the curb rein is applied, causing pressure to be applied to the chin groove in combination with pressure to the poll, the longer the shank of the bit the more severe the pressure.
When fitting a curb chain it must have all the links smooth and lying flat and when pressure is applied to the rein the shank of the Weymouth should be at a 45-degree angle to the mouth. If the mouthpiece of the curb has a high port then the roof of the mouth will also be affected.
The Curb Bit Mouthpieces
Curved Mouthpiece – Allows even pressure to be applied inside the mouth and more room for the tongue, this type of bit can be useful for horses with sensitive bars, due to the distribution of pressure.
Ported Mouthpiece – Allows more room the tongue and will also affect the roof of the mouth when curb rein applied.
Curb Bit Cheeks
Sliding Cheek – The sliding cheek allows the mouthpiece to move up and down and is a great bit for horses prone to leaning or becoming fixed in the mouth.
Fixed Cheek bits – The fixed cheek horse curb bits will remain fairly still inside the horse’s mouth and is a great bit for horses who are very light in the mouth or prone to going behind the vertical.
