Stop choosing between power and control. The Hyper Hammer 4.0 produces major levels of both in a lightweight, deftly maneuverable frame.

Hyper carbon is the lightest, stiffest, and strongest material ever used in tennis racquets. Compared to titanium, hyper carbon is 4 times stiffer, 65-percent lighter, and 4 times stronger. It is used in the horizontal axis cross section, creating more power. Hyper carbon is also used in the vertical axis cross section, increasing torsional stability, giving you more control. Hammer technology maintains head weight, resulting increased stability and more power, as well as producing a larger sweet spot. is always serving up hot deals on high performance sports equipment.
