Bomber Bit Sizing: To measure the mouthpiece, take the length from the outside of the horse's lip on one side to the outside of the other. To make this easier, consider using the Bombers Bit Measure.
Measure in millimetres on the mouthpiece of the bit ONLY (i.e. measure the length of the blue mouthpiece pictured below, not including any of the silver cheekpieces). The bit photographed is a 135mm bit.
The sizing chart below shows the standard sizes for straight Bomber bits used on Buttery Horse Co: Small (120mm) Medium (125mm) and Large (130mm) for most 15hh-15.3hh Thoroughbred polo ponies in Australia. Larger warmbloods, eventers and hunters who have thicker lips and wider jaws may need 135-145mm. A few thoroughbred polo ponies will need Extra Small (115mm), which can also be ordered as a custom size. Our standard sizes include the following variations:
Bombers says:When the mouthpiece is too large, the bit joins move and the curves can sit incorrectly in the mouth. This leads to the mouthpiece applying pressure in areas it should not be. An oversized bit will also create too much movement in the mouth, allowing the bit to slide from side to side within the mouth. This movement causes discomfot as well as background noise to the riders aids.
