Tennis players, get ready to up your game with Babolat RPM Team strings! This 17-gauge black string gives you the perfect balance of what makes polyester great - insane spin production and maximum durability - but with added flexibility for better comfort. If you've tried other polyester strings but found them too stiff or harsh on your arm, the RPM Team could be your solution. The soft feel means you can play longer without that uncomfortable vibration, while still getting that crazy spin that makes your shots dip and dive. The 17-gauge (1.25mm) size gives you great playability and feel, and the black color looks sharp on any racquet. Whether you're a competitive player looking for every advantage or a recreational player wanting better performance, these strings deliver. They're the kind of strings that make you feel more connected to your shots while giving you that extra bite on the ball that creates heavy spin. Perfect for players who want poly performance without sacrificing comfort. Your groundstrokes will never be the same once you experience the control and spin these strings provide!
