The changeable Loxley gullet bars are available in 6 sizes, from NM – XXW.  They also fit the Cavaletti saddles (with the MW being purple instead of teal)

The bars are designed to compliment the broadness of the horses spinal area as the broadness of the horse increases, this allows the shape of the tree to adapt on a linear scale from an A-frame shape on a narrower horse to a wide head on a much broader horse.

Using the easy clip in system the bars are easy to fit and secure.
