At only 175 grams, the Radical Edge plays like many of the frames the top pros use. Molded tubes in the throat of the racket called Power Channels™ allow the main strings to be longer and create maximum throat stiffness for an increase of raw power every player needs. In addition, it features the Inner Grommet System Technology (IGS2), which delivers optimal stiffness and provides you with a good feeling for how you hit each shot, so you can control your power even better. The Radical Edge is perfect for beginners and intermediate players that demand high performance without breaking the bank.
