SL-70

SL-70

Updated this year with Nano Technology and Nano Superlight Resin, the SL series uses the 'Muscle Tec' string system which is designed to enlarge the power zone of the racket by allowing the strings to move over a smooth rounded surface rather than being static as in conventional rackets.  'Muscle Tec' enables the strings to be strung at a lower tension yet still gives a high tension feel.
