The Wilson Hyper Hammer 120 has a very light frame with most weight located in the top of the racket. As the name of the racket suggests, it´s just like a hammer. During a shot, the extra weight in the top of the Wilson Hyper Hammer 120 creates a lot of explosive power. Despite the low weight, the racket is extremely strong. Wilson has achieved this fantastic combination by making the frame with Hyper carbon. This material is lighter than titanium and many times stronger than graphite.
