Stubben Fine Line Flex Eggbutt

Slightly flexible wide ported mouthpiece from Stubben, available in many styles but only up to a 135.

16mm thickness

The 1302 Fine Line Flex Eggbutt Snaffles´s mouthpiece is made from flexible, food-grade PU, offering a warmer feel in the mouth even at lower temperatures. A concealed metal core ensures break-resistance and security. The anatomically shaped mouthpiece follows the natural line of the horse’s mouth, lying evenly across the tongue and bars while a slight tongue relief reduces pressure. The fixed eggbutt rings prevent pinching at the corners of the lips and ensure improved lateral stability, allowing the bit to sit more quietly in the horse’s mouth.

If you already have a bit that fits your horse well, you can use it as a reference for choosing the correct size.

If not, measure your horse’s mouth width by placing a bit sizer or a soft cord/string in the mouth at the position where the bit will sit, mark the ends, then measure the distance. The bit width should be such that the rings rest just outside (or very slightly beyond) the lip corners—if the bit is too narrow, it will pinch; too wide, it will shift side to side. For loose ring bits, allow a little “play” (1cm on one side) so the rings can rotate freely without pinching the lip

After each ride, rinse or wipe the bit to remove saliva residues. Once cleaned, dry the bit with a towel.

Any bit can cause pain if used roughly or improperly. The wrong size can also be painful for the horse.
