Racer™ piggin strings are more than just a good feeling body. The eye of every string is constructed using a special process that results in an eye that will not turn. Racer™ eyes are the right size, and hand sewn with rawhide burners for speed and smoothness. Each string is treated with a specially formulated wax that penetrates into the string fiber. This creates just the right balance and body to add speed to your tie.
