Bomber DC Morgan Bomber Blue Swivel

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. 

Bomber Bits should fit snugly, with no gaps between the lip and the start of the cheekpiece. They should sit flat against the lips, not squeeze the lips in.

• Measurements are taken of the mouth from just outside one lip to another (i.e. measure to the inside of the cheekpieces). For example, from inside the Tbar on one side to the inside of the other.
• The easiest way to do this is to measure against a bit with a straight mouthpiece (such as a Mullen mouth)
• Bit rubbers may take up an extra 3-5mm
• Control plates and other broken (3-piece) Bomber bits sit over the horse's tongue rather than straight in the mouth, so need an extra 5-10mm. This is included in our standard sizing. 
• Solid mouthpiece bits such as the Happy Tongue, Mullen or ported bar bits are slightly more forgiving if the bit is too big, but it will not be ideal because when you turn, the bit will shift in the horse's mouth. 

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.
