The Black Ace first appeared way back in 1979. Tennis has obviously evolved sense then, and ProKennex has a modern Black Ace 315 Tennis Racquet to continue the tradition of arm friendly performance. The Black Ace is designed to achieve the perfect balance of power and stability thanks in part to the new material and geometry. A unique trapezoidal structure in the racquet shoulders allows for increased ball speed and flexibility. This combined with the elliptical cross section in the racquet's head and Spiral Tech Carbon create a frame that is undeniably comfortable and powerful. Pro Kennex is most known for their Kinetic System, which utilizes movable mass in sections of the head to increase power in the upper hoop, and reduce frame twisting.
The Black Ace 300 is 11.1 ounces unstrung, and an open 16x19 string pattern. With a flex in the mid fifties, the Black Ace is one of the most flexible racquets on the market today. The frame is a comfortable choice for those with medium to fast swings, that want more comfort and power in a modern frame.
