The BIOMIMETIC 500 25 is designed for advanced juniors who seek the same all round power and control as the standard 500 but in a shorter 25 inch racket length. The ultra light weight specification makes the tennis racket very manoeuvrable and the 16x18 open string pattern means there is plenty of potential for spin generation.The frame is constructed with 100% premium Aerogel enhanced graphite and features Dunlop's new Biomimetic technology. HM6 Carboin enhances the racket feel; Aeroskin technology reduces aerodynamic drag making the tennis racket faster through the air and the Gecko-Tac grip gives ultimate control in all conditions.
