YONEX ASTROX 77 SHINE YELLOW 4UG4

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 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.

AERO & BOX FRAME?Combines solid hitting feel and quick swing.

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.

The single-pass grommet hole construction provides more grommet holes for a more high-performance stringing pattern.

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

The built-in solid feel core cuts harmful miscellaneous vibration at impact. Solid feel core is carried in all racquets manufactured in Japan.

The slimmest racquet ever produced by YONEX vastly reduces air resistance whilst providing maximum feel.

The control support cap provides an 88% wider flat surface compared with an ordinary racquet for easier gripping, fast follow-through and the sharpest maneuverability.

The lightweight T-Joint increases stability of the shuttle on the strings, maximizing power and control.
