The double broken snaffle bit ''Flexi'' is a frequently used simple bit. The sliding rings enable a slight gag effect for horses needing a simple mouthpiece with a little upwards action.
The ''double broken'' part is ideal for horse with a flat palate. In any case, it fits better to the shape of the palate and the position of the tongue.
Furthermore, this ''Flexi'' version (the bit is covered with a synthetic material of ''resin'' type) is recommended for sensitive (young) horses and mares, sometimes more reluctant to steel.
