Hi-Copper Mouth Bit with Stainless Steel Cheeks/Rings.
Thinner Mouthpiece Bits
This thinner type of mouthpiece is not as mild as the standard size as the mouthpiece is thinner therefore the pressure is distributed over a smaller area. This thinner type though may be useful though if your horse has large fleshy lips and/or tongue, which some of the larger breeds have as they have less room in the mouth for a thicker bit.
The loose rings snaffles make a more mobile bit than an eggbutt or fixed cheek bit, which should encourage your horse to keep a relaxed jaw and mouth the bit. The loose ring may be useful if your horse leans on the bit, or takes hold, as the bit is always movable so the horse cannot take hold as easily as they could with a fixed cheek. This bit is also useful for gaining contact as the movable mouthpiece enables the bit to fit the mouth, contour the tongues natural position and sit comfortably.
The French link has proven one of the most popular mouthpieces; it has 2 joints, which means the pressure of the bit is distributed over both the tongue and bars of the mouth. Because the mouthpiece has two joints, it shouldnt cause any interference with the roof of the mouth. The French link uses tongue pressure to encourage the horse to go on the bit and has bar and lip pressure but not a squeezing action like that of a bit with a single joint. The more joints a bit has the less likely the horse is to lean as the bit becomes more mobile.
An Alternative to the French Link is the Lozenge bits.
