GAMMA has moved to the molecular level, real nanotechnology, to improve elasticity, resiliency, and shock absorption. The nanotechnology was first used to create GAMMA TNT string; now the technology is applied to carbon fiber composites to create the IPEX Nanotechnology. Each IPEX racquet concentrates different high modulus carbon fibers throughout different strategic areas of the racquet, improving power, control, and feel. The resilient IPEX carbon fiber composite structure returns energy faster, snapping back to its original position upon ball impact for greater energy transfer than ordinary carbon fiber structures. Stronger and more concentrated carbon fibers provide perfect stiffness for greater stability, resiliency, and energy transfer to the ball for maximum performance.
