This classic power racket has a strong frame that allows you to quickly change the pace of the game. The 'N' of the Wilson N120 stands for the N-code. The N-code is a nanotechnology process that manipulates the racket structure to improve the performance of the frame. N-coded rackets are 2 times stronger and more stable and up to 22% more powerful than regular rackets. The larger openings (power holes) on both sides of the frame ensure that the strings are more flexible. This creates 25% more power on the balls you hit.
