Premium standard for natural gut tennis strings, and is now updated with BT7 technology for 15% better durability. BT7 permits a larger contact surface of the natural gut fiber bands. Also available in black!
Babolat RPM Team 16 is a new co-polyester and is a slightly more forgiving alternative to RPM Blast. The infusion of micro air bubbles into the string permits additional flexibility without sacrificing durability. Also an excellent choice for big hitters looking for extra spin. Octagonal (8-sided) cross-section adds the extra bite on the ball for added topspin and slice.
