The D bits or Dee Cheek as they are also referred to, are a member of the Snaffle family. 

Often seen in racing when a slightly larger external Dee shaped ring would be used. A halfway house between an Eggbutt and a Full Cheek, the Dee has a short length of metal that protrudes both above and below the mouthpiece. The top and bottom of this are attached by joints to the loop that forms the outer rings of the bit. These allow the bit’s cheeks to move freely and give the distinctive “D” shape from which it is named. Normally the Dee cheeks will be made from Stainless Steel even if the mouthpiece is of another alloy or material.

The Advantages of Dee Cheeks 

---

With lengths that are shorter than those of a full cheek, it has the advantage of not being too long and so avoiding the worry of catching on the nostrils or tack when in use. This side pressure can also be useful when working the less experienced horse as long as it is supported by competent rider aids. Additionally, the Dee cheeks also help to keep the mouthpiece central in the horse’s mouth and can prevent it from being pulled adversely from side to side as might be the case with the less exercised rider. Consequently, they are useful in riding schools and some RDA groups.

As there is no joint directly by the horse’s mouth, this design of bit is less likely to cause pinching to the lips.

It is available in a wide range of mouthpieces to accommodate the requirements of many mouth types including fast twist, slow twist, copper and more.
