When you strike a ball with a Core1 Pro Kennex tennis racquet each of the independent graphite cylinders creates a separate, opposing shock wave. When the two opposing shock waves meet at the wood spine they counteract and cancel out each other, eliminating the harsh negative impact shock and vibration you can sometimes experience with a typical tennis racquet. Ionic technology delivers advancement to the famed Kinetic Technology adding a Jetron™ fill to the chambers. Jetron™ is a remarkable inelastic composition of ionizing carbon structures used as a coating for the Kinetic™ mass and chambers, creating a completely clean and unique feel of pure atomic energy. Use Pro Kennex tennis rackets and technology to upgrade your tennis game!
