Special Instruction:

Yonex ASTROX 77 racket is built using with Rotational Generator System. The counter balanced head adapts to each shot, helping you to control the drive and attack the opposition with increased acceleration, steeper angle and power on the smash.

This racket helps you to lead the attack with increased power and control.

  • Smash power up 7.1% (The difference between the initial speed and the final speed is minimized in order to be launched strongly)
  • Smash angle is 2.3° steeper *Tested by Yonex (Measurements by swing robot)

Special Features

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.

Rotational Generator System
Weight Distribution - 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 a rapid succession. 



ASTROX 77 uses a world’s-first, new dimension graphite material, Namd, which 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 Namdnanomaterials 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.


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

The square-shaped ISOMETRIC frame shape is designed to keep vertical strings at a similar length, as well as the horizontal strings to produce an expanded sweet spot in all directions.

New Build-in T-Joint
‘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.

New Control Support Cap
YONEX has designed a new octahedron shaped control support cap that reduces air resistance whilst encouraging nimble handling.

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