The Head Graphene Radical 160 racketball racket incorporates a 106in 2 (684cm 2) head with a diagonal 16x 16 string pattern that helps reduce vibration. It has a light 160g (5.6oz) frame that is evenly balanced to meet the needs of the players who tend to favour an all-court game. The racket is constructed from Graphene, the worlds strongest & lightest material that makes it easier to swing & enables more powerful shots. It features the Durazone & Power Channels technology which eliminates 33% of the grommet holes in the head of the racket & the Inner Grommet System (IGS2) that ensures optimal stiffness, but with less weight. In addition, the Power Stabiliser delivers amazing power even on off-centre shots.
