||A bit of magic. Copper and the effective curved mouth design make Kangaroo bits magical! Copper responds quickly to heat, offers comfort for the horse, encourages salivation and acceptance of the bit. Stainless steel rings and cheeks. A touch of nickel has been added to the special metal composition to ensure the bit retains an attractive silver color that even to a tack judge at a competition looks like stainless steel. John Dewsbury developed the first Kangaroo bits in 1831 in Walsall, England. Today, we continue on with Dewsbury's commitment to use only the finest and safest materials to produce bits that are of a higher standard and quality than anything else available.
