  • Steffi Graf
    Tennis Player
  •  Stefanie Maria “Steffi” Graf is a former World No. 1 German  tennis player. In total, Graf won 22 Grand Slam singles titles,  second among male and female players only to Margaret  Court’s 24. Wikipedia

This racquet was made for Steffi Graf in late 2005.  When you, or me in this case, pick up the racquet the first reaction is wow, this is heavy!  You would be correct! The racquet is standard length but the long grip makes it look longer so the optics contribute to the recognition of weight.

And, the head size is 85 square inches not 95 as would be expected given the “95”designation on the racquet.

Another interesting thing about SMU (Special Make Up) racquets is the data printed on the inside of the shaft.  You can not depend on it!  This racquet has all the markings of a standard nCode Six-One 95 but the string pattern is actually 18×20 not 16×18 as designated on the racquet.
