D-Ring Snaffle Bit, Double Jt. 16mm, Stainless St. No Color 135 mmD Rings prevent the bit from being pulled through the horses mouth so it lies more steadily on the tongue giving a more comfortable feeling. Gentle pressure is pivoted directly onto the tongue ensuring light and precise rein aids. The fixed rings enable the rider to have a good contact with the bit. The additional contact surface from the cheeks on the mouth corners supports guarding and sideways acting rein aids.
