Endorsed by Sir Andy Murray, the Head Graphene 360+ Radical Pro tennis racket is designed for a versatile, advanced all-court player looking for improved playability and a high level of control. With the signature Graphene 360+ technology, the racket offers optimised energy transfer, enhanced flex and a clean impact feel, whilst control and stability come from its 98in2 (630cm2) head and a 315g (11.1oz) frame weight. Great for attacking the ball at an aggressive angle, the Radical Pro has a dynamic 16x19 string pattern for maximum spin and added power. Head light balanced for speedy handling, the racket uses Sound Grommets technology for enhanced power via greater string movement. It is the heaviest member of the Radical family and ensures a solid feel at impact and surgical precision. Tennis Rackets.
