BLACK GRANITE - THE MATERIAL USED BY PROFESSIONALS
Fischer's racket generation, made of rock
Black Granite is a volcanic rock fibre that comes from Asamer which Fischer has used with the name "Black Granite" for the first time in tennis rackets. The material is extremely tough and particularly resistant tro fluctuations in temperature. "These properties make the racket extremely stable and precise" explains Michael Reiser, director at ASA.TEC
