D rings also work like a fulmer but without the risk of getting caught on a Haynes etc and look less Like a baby bit. Will help with steering. D-ring snaffles transmit the pressure from the rein aids directly onto the tongue and lower jaw without leverage action on the poll. Due to the fixed cheeks the rein aids reach the tongue in a more direct way. This is the perfect bit to assess every horse. Unique, patented, 45° angle to lozenge, lies perfectly flat on the horses tongue when the rider has a contact. Anatomically adapted mouthpiece. The use of the D rings with this bit will act as an eggbutt, therefore lying still in the mouth, no chance of pinching the lips. Has a more direct effect due to fixed cheek.
