Steep Attack

Overwhelm the opposition with the fast and powerful ASTROX. For players who demand a steep angled and devastating smash, taking the point to their opponent.


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 NANOALLOYTM Technology of Toray Industries, Inc.
