Thanks to its perfect balance between power and flexibility, the professional frame of the PROKENNEX BLACK ACE 300 TENNIS RACKET – developed using new materials and an updated geometry – gives exceptional quality ball feel. 

This Prokennex tennis racquet comes equipped with their world famous Kinetic System technology. The Kinetic System consists of micro-spheres (Kinetic Mass) contained in capsules which are built into the frame. As the tennis racket moves in preparation for the shot, the Kinetic System stores kinetic energy in the Kinetic Mass, which upon acceleration, gather on the walls of the capsule on the side opposite to the ball. During impact, the tennis ball is compressed and the strings flex, during which time the Kinetic Mass moves towards the ball, unleashing additional energy. Immediately post the impact, the Kinetic Mass spheres move freely to stabilise themselves while instantaneously rebalancing the frame. In addition to stabilising the frame, the Kinetic System increases the usable area of the string bed, facilitating the success of the shot.

Once the ball leaves the racquet strings, the Kinetic mass microspheres move, using all the energy left in the frame. Players will notice a pleasant feeling of comfort while playing and a drastic reduction in fatigue and in stress in their arm, with an increase in the precision and power of their tennis game. Immediately after the ball leaves the racquet strings, flexibility is activated.

The new nanotechnology of the Spiral Tech graphite filaments ensures extreme flexibility and unprecedented acceleration. The trapezoid shape of the shoulder grows out of the handle in perfect harmony with the oval shape of the head. This geometry allows complete stability of the string bed, giving a clean and effective impact with the ball. By stabilising torsion in the frame, the Kinetic System enhances the player’s potential, shot after shot.

Black Ace is designed for players who want to perform at full power without ever sacrificing total control of the racket in terms of precision and manoeuvrability. This tennis racket is weighted for intermediate and advanced players. The arm-friendly Black Ace 300 tennis racket offers easy acceleration that makes it easier to whip up heavy spin and pace.
