The all new Kinesis racket has rewritten the rule books with its revolutionary vortex shedding frame geometry. The Kinesis is ideal for advanced players seeking control by combining a lightweight, even balanced frame with a medium flex shaft. The racket has been engineered with a 90 degrees twist at the 2, 5, 7 & 10 o'clock positions to reduce aerodynamic drag resulting in improved head speed and maneuverability. In addition, Micro Grommets keep the strings rigidly in place to allow pin-point accuracy along with enhanced power.
