Shires 550 Flat Ring Jointed Eggbutt

A thinner mouthpiece can make this bit a little stronger, however, it may be a more comfortable option for a horse with a small mouth. The smaller sizes of this bit come with smaller rings to ensure the bit remains in proportion. Mouthpiece thickness: 14mm (3.5), 15mm (4 – 4.75), 17mm (6). Cheek height: 55mm (3.5, 4, 4.5), 75mm (5, 5.5, 5.75, 6).
