The ISOMETRIC™ equalizes the length of the main and cross strings in the string-bed, enlarging the sweet spot for more consistent accuracy even on off-centre hits. The single-pass grommet hole construction provides more grommet holes for a more high-performance stringing pattern. The built-in solid feel core cuts harmful miscellaneous vibration at impact. Solid feel core is carried in all racquets manufactured in Japan. ‘NEW’ Built-in T-Joint is manufactured from a special lightweight plastic combined with epoxy resin and foaming agent that enhances quality and performance by increasing the stability of the shuttle on the string bed and through the air. AERO+BOX Frame combines solid hitting feel and quick swing.
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.
*approximate measurement when compared to a conventional racquet shaft, tested by Yonex.
