Max Control Full Cheek Snaffle Bit
OK, here is my description!
It should be named the wonder bit/biofeedback bit/quieter than the rider's hands ever could be bit, et al. This impressive little bit is moveable as a normal 3 piece bit until pushed outward, when it locks into position and becomes like a mullen mouth. For a super sensitive horse, it is fabulous, because it really is quiter than your hands ever could be and you are allowed to more easily give slightly within the contact. It could be a bit "sturdy" with super busy hands, but is also good for the horse that plays with the bit too much (another name! "Zen bit"). And for the horse that likes to spit out the bit, this bit is pretty hard to spit out!!! The fullcheeks are really great for horses that need extra help with lateral stiffness and super for youngsters to teach lateral suppleness. Thickness is 16mm (narrows towards center)
So now, here is the official description!
Horse & More by Herm Sprenger's Max-control bit is a double-jointed bit that looks similar to other double-jointed loose ring snaffles but locks at a certain angle to help the rider maintain maximum control. This bit lies well in the horse's mouth while working properly. When the horse resists the rider's hand, there is a rigid locking effect that turns the bit into a straight bar. This bit is a great training aid or daily bit for horses who like to pull or resist contract. This bit by Horse & More, a division of Herm Sprenger, is currently available in the sizes shown above.
Sizes are transposed:
5" = 125mm
5.5" = 135mm (between 5.25 and 5.5"; closer to 5.5")
5.75" = 145mm
