Yonex Astrox 77 Badminton Racket

Yonex Astrox 77 Badminton Racket

Made in Japan

The Yonex ASTROX 77 badminton racket is an attack-orientated model which can take the lead in a high-speed game with a design that can deliver powerful, steep smashes, allowing you to dominate the court. The new ASTROX 77 racket is equipped with Rotational Generator System. The counterbalanced head adapts to each shot, helping you to control the drive and to attack the opposition with increased acceleration, steeper angle and power on the smash.

・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)



Designed for intermediate to advanced players, Yonex adopts the new dimension graphite material 'Namd' making an improvement by enabling more powerful shots. This design allocates weight to the upper part of the frame, the joint part, and the end of the grip, resulting in less momentum lost and preparation for the next shot is rapidly made.

ASTROX 77 uses worlds 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 Namd, nanomaterials directly adhere to the graphite fibers and the degree of adhesion between 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.

From the initial movement of the player to the impact, the new dimension graphite is difficult to harden, and the shaft extends and accumulates energy due to the speed of the fast swing. Since the follow-through of the swing is smaller after the direct impact with the shuttle, the swing speed drops and the new dimension graphite regains hardness and strengthens the resilience of the shaft, allowing the energy to explode rapidly before returning to its original state.
