Full Cheek Snaffle
The cheeks of these bits extend both upward and downward, tapering as they get farther away from the mouthpiece, with a half-moon ring similar in shape to the Dee-ring or eggbutt (depending on the design). The long sides provide a great deal of lateral guiding effect. The full cheek without bit keepers is more fixed in the mouth than a loose ring, and thus has a similar action to the eggbutt or Dee-ring. Use of bit keepers, however, makes the full cheek even more fixed than the Dee-ring, concentrating bit pressure on the bars and tongue.
