Introducing the the Ki 10 (290g)! Like the heavier Ki 10 (300g), this lighter version offers a dangerous combination of spin, precision and power. At 290 grams (unstrung), this racket moves fast, making it easy to swing bigger when loading the ball with pace and spin. This racket benefits from legendary Kinetic Technology which uses movable mass in the head to reduce the amount of shock that reaches your arm. Other arm-saving technologies include a Comfort Cap, which adds Kinetic technology to the butt cap to attenuate residual vibrations. This racket also comes with a firm Spiral Tech Carbon layup to create fewer impurities and air bubbles. The result is a more stable and powerful feel when striking the ball. Intermediate players looking to dominate the court with heavy pace and spin should give this stick a very serious look. The fact that it is one of the most arm-friendly rackets in its class is a nice bonus.
