A new, adaptive frame built for optimal performance, the HEAD Graphene Touch Speed Adaptive gives players all they need and more in a truely customizable package. HEAD engineered the Speed Adaptive with the worlds strongest and lightest material to make their Graphene Touch racquets 30%* stronger providing an optimized weight distribution for a faster swing and more power. By using Graphene Touch in the racquet shaft, HEAD has been able to dampen the vibration produced by the racquet giving the racquet power that never felt so good!The Speed Adaptive is a huge step up from HEAD`s previous Adaptive String Pattern (ASP) racquets. While these racquets do still have ASP, they took it a step further and with the Adaptive Tuning Kit (sold separately) the user can change the length, string pattern, and weight of the racquet.
