Karakal Black Zone 30 Badminton Racket Graphite 82g Isometric Head Flex Frame The Black Zone 30 is a great all round racket. It allows you to play with a controlled swing to aid your accuracy but also allows the player to push their opponents back with the depth of shot, the frame design cuts down on air resistance allowing for higher head speed to generate more power. The 7.5mm shaft reduces the flex allowing you transfer power from your shot directly to the shuttle. The theory behind these frames was to provide a badminton frame to suit any need , each of the 4 frames has a slightly different frame design giving them all a different feel. We kept the colours simple by using black satin finish on all the frames but adding splashes of bright colours to give each racket an individual identity. All frames use an Isometric head shape.
