Offering the Power Surge technology, developed with David Palmer, the Ion Element PSX racket from Black Knight provides reduced vibration, extra stiffness and power. It incorporates the Thin-K technology delivering an aerodynamic frame and the Nano-Crystalline Technology (NCT) allowing for fine-tuning of the weight and balance and ensuring greater control for hard hitters. The PowerNick 19 string results in a better bite on the ball and less air resistance, whilst the Thermal Core technology guarantees a stronger and more stable frame. In addition, the racket features the Power of 6 technology for optimum performance.
