NANORAY Z-SPEED did not get its name at random. This racket was put to the test and made the World's fastest smashing record.
NANOMETRIC
Lightweight
NANOMETRIC* improves the bonding strength between the carbon fibres enabling us to take racquet shaft construction to another level. By reducing the amount of carbon in the shaft to make it 60%* thinner than a conventional racquet whilst retaining stiffness, YONEX has created a revolutionary lightweight racquet with lightening head speed and control.*NANOMETRIC is the new material which applies the NANOALLOYTMTechnology of Toray Industries, Inc.
