On this page you can purchase Power Cord in sets (one set is enough for one racquet). Power Cord, by virtue of its relatively high elasticity, is an extremely comfortable and powerful polyester tennis string. With this string you will enjoy the significant spin and durability advantages of a polyester together with a livelier feel approaching that of a non-polyester. Power Cord's performance is equivalent to other industry leading 'soft' polyesters but, like all Golden Set products, available at an affordable price.
