At 170 grams, the Graphene 360+ RADICAL 170 is designed for those who look for power. It is slightly heavier than the 160 version and comes more evenly balanced, which means that it packs a lot of power in an extremely maneuverable design. 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. While used by top pro players, the RADICAL 170 brings state-of-the-art power to the masses.

Auxetic 2.0
Auxetic engineering gives a unique experience compared to non-Auxetic constructions. Due to their internal properties, Auxetic constructions expand when a "pull" force is applied and contract when squeezed. The bigger the applied force, the bigger the Auxetic reaction. The Auxetic cage means you feel the impact right when and where the action happens, it is the ultimate connection between player and racquet.
Graphene Inside
Refers to Head's use of Graphene, the world's strongest and lightest material, within the construction of their tennis rackets to improve performance. The Graphene is strategically placed to optimize the racket's weight distribution, enhance energy transfer, provide greater stability, and improve power and control. Head has developed several versions of this technology, such as Graphene XT, Graphene Touch, Graphene 360, and Graphene 360+, each with advancements in how Graphene is integrated to achieve different playing characteristics.
Inner Grommet System 2
The next generation of HEAD's revolutionary Inner Grommet System Technology, IGS2, eliminates exterior grommet holes delivering optimal stiffness, but with less weight.
Power Rail
PowerRAILS Technology is an all new advanced beam cross section in the throat area of the racquet. PowerRAILS dramatically increases torsional stiffness delivering unprecedented power with stunning pinpoint control.
Power Channels
HEAD engineers have eliminated 33% of the grommet holes in the head of the racquet by developing innovative shared ports. In addition, Power Channels have been lowered deeper into the throat of the racquet.
Soft Grip
AFP
More power or more control - now you can have it all in one racquetball racquet. The new Adaptive Fan Pattern (AFP) technology allows you to choose between two different pattern depending on your individual style of play and personal needs. You can choose between the straight string pattern to maximize your power game and the special fan-shaped pattern to optimize your ability to control the ball. The new AFP technology is available in the new Radical racquet series.
