Recommended StringDunlop Silk NO CoverThe lightest racquet in the 400 series, the Biomimetic 400 Lite is ideal for players with a mid swing style looking for a lightweight, yet powerful racquet. The light weight and even balance make the racquet easy to use and very maneuverable giving plenty of access to spin. Power comes from the combination of new technology and the stiff 70RA frame. The 400 lite is constructed with premium Aerogel enhanced graphite and features Dunlop's new Biomimetic technologies. Cx Technology in the racquet head creates a more powerful aerodynamic profile. The anti friction grommet system allows more string movement for enhanced power from the string bed. Anatomic construction in the throat, inspired by human bone structure, adds stability and control to the racquet. HM6 Carbon enhances racquet feel, Aeroskin Technology reduces aerodynamic drag making the racquet faster through the air and the Gecko Tac grip gives ultimate control in all conditions.
