Stainless steel bits are a good value. The metal is is strong, durable and resistant to tarnishing and rust. This stainless steel French Link Bradoon features a 14mm mouthpiece with 55mm loose rings. The loose rings enable the mouthpiece to rotate freely, which is preferred by some horses that use their tongue to move the bit. In the center of the mouthpiece, the small peanut-shaped French link lays flat across the tongue and provides more mobility than a single-jointed mouthpiece. Some horses may prefer the feel of a French link and go lighter in it, with less leaning on the bit.
