Uses an updated version of the Isometric Head which provides an even larger sweet spot. For additional comfort, ultra-thin flexible fibers have been added to the frame, called Minolon. The new model still uses the enhanced 2G-NAMD SPEED technology, where durable carbon fibers are strategically placed on the frame for more power and a better feel.
The frame construction has also been slightly changed, featuring a thicker and more convex profile for greater stability and more power.
At the same time, the throat of the racket retains the M40X graphite, which means it does not twist and thus better transmits energy back to the ball. This increases power, and improves comfort, stability, and control.
Due to its specifications, it offers enough power for backcourt play, while at the net it is fast and highly maneuverable.

ISOMETRIC: The head shape enables an easier swing, better maneuverability and 7% bigger ideal hit point.
VIBRATION DAMPENING MESH: Material is in the frame and filters 30% of vibrations, while bettering the feeling and comfort.

M40X.: the use of a stronger graphite in the frame offers more power, while a more flexible graphite in the neck offers extra comfort, stability and control.
LINER TECH: increases the entry angle of certain strings, which increases the string movement, which then offers a bigger ideal hit point.

2G-NAMD Flex Force: Flexible graphite matrix, for a more optimal response and more spin.
