max control multi ring bit locking mech double jt 16mm stainless st metallThe MAX Control is a double jointed bit which, at first glance, cannot be distinguished from other double jointed loose ring snaffles. However, it is a correction or training bit which locks at a certain angle and thus becomes a straight bar. The bit lies very well in the mouth when the horse is working properly. When the horse opposes the riders hand the more intensive rigid effect occurs.
