Babolat RPM Blast 17g Tennis String is designed to produce a lot of spin and really control the ball. It is a co-polyster monofilament string that bites in to the ball and as is expect with a polyster the string will quickly return back to its normal position.

ITS THE WINNING CHOICE FOR RAFAEL NADAL, JO-WILFRIED TSONGA AND SAMANTHA STOSUR. THE RIGHT STRING FOR PLAYERS WHO WANT MORE CONTROL AND INCREDIBLE SPIN!

Packed with the latest technologies, this high-density co-polyester monofilament string offers a totally unique feel and a powerful, ultra-high-speed response. The octagonal section and cross-linked silicone coating allow the strings to quickly return to their original positions and “bite” the ball better for maximum spin.
