At 180 grams, the Graphene 360+ RADICAL 180 is more head-light, which directly translates into maximum maneuverability. It features the new Graphene 360+ technology, a combination of Graphene 360's energy transfer and innovative spiralfibers for an enhanced flex and clean impact feel. In addition, it comes with HEAD's Inner Grommet System for optimal stiffness and a solid feel. We also lengthened the main strings by creating molded tubes in the throat of the racquet. These Power Channels™ increase the stiffness in the throat for an incredible amount of raw power. The RADICAL 180 is the perfect choice for the serious player who needs a head-light power weapon.
