The McHardy is a combination of a jointed Happy Tongue with the Buster Roller. An excellent bit when more control is required, allowing at the same space for the tongue. This is because it is ported, which allows space for the tongue and relieves pressure in this area.
This bit will be suitable for you if your horse has a large and/or sensitive tongue and tends to lean on the bit .
It is readily available in a full cheek and a 2.5 ring.
