The Dunlop Aerogel 4D 500 (5Hundred) Tennis Racket is a classic and user friendly intermediate frame with a forgiving head size, slight head light balance and medium weight for a great blend of power and control. A solid feel is created by the latest 4D braiding technology at the key stress points, and the slightly open string pattern enhances the control of the shot. This means the average player can generate greater swing speed without sacrificing control or feel, thus producing a better all round game. This is a great improver’s racket who wants to have a tennis racket that will still suit as they progress and get better at the game.
