Yonex Astrox 77 Pro Unstrung

Namd Revolutionary Graphite: A world-first, new-dimension graphite material, Namd, greatly improves the adhesion of the graphite fibers and resin by attaching nanomaterial directly to the graphite fiber. In high performance racquets, it is common to combine nanomaterials with resin that connects graphite fibers, but in Namd, nanomaterials are directly adhered to the graphite fibers, and resin is greatly increased. This major improvement produces a shaft that flexes and stores energy, delivering explosive force on impact with the shuttle.

NANOMETRIC Lightweight: NANOMETRIC* improves the bonding strength between the carbon fibers 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 the stiffness, YONEX has created a revolutionary lightweight racquet with lightening head speed and control.

ISOMETRIC Enlarged Sweet Spot:  ISOMETRIC^TM technology continues to help the world’s greatest players achieve global success. Developed over 30 years ago, the ISOMETRIC^TM design increases the sweet spot by 7%*. Compared to a conventional round frame, a square-shaped ISOMETRIC^TM racquet generates a larger sweet spot by optimizing the intersection of the main and cross strings.

Rotational Generator System: By applying the counterbalance theory, weight is distributed throughout the grip end, frame top, and joint for maximum control. The transition to the next shot can be performed smoothly, with rapid succession.
