This Aurigan® Large Ring Loose Ring Bit by Herm Sprenger features 90mm rings and an 18mm Aurigan mouth. Aurigan is a nickel-free alloy comprised of 85% copper, 4% silicon and 11% zinc. It oxidizes rapidly, producing a pleasant taste in the horse’s mouth. This in turn encourages optimal acceptance of the bit.
This HS Aurigan® Bradoon has a 16mm Aurigan mouth and 55mm rings. Aurigan mouthpiece metal, manufactured only by Herm Sprenger, encourages most horses to chew and salivate, leading to a soft mouth and optimal bit acceptance .
