Eggbutt bit with a movable link. A bit that sits quietly in the horse's mouth. Often ideal for sensitive horses that are fussy in the mouth or unsteady in the contact. The rotating link allows each side of the mouthpiece to move independently. An eggbutt bit creates a steady contact and prevents the corners of the horse's mouth from being pinched. Check your barrel/cylinder bit to make sure that the joint is not worn. Rings 60 mm. Thickness 12 mm.
