Description Technical Specs

The Yonex ASTROX 77 Shine Yellow badminton racket is a little more head heavier racket offering more power compared to the ASTROX 77 Metallic Blue badminton racket. Astrox rackets are an attack-oriented 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 counter balanced 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.

ASTROX 77 uses a world's-first, new dimension graphite material, Namd, which greatly improves the adhesion of the graphite fibres and resin by attaching nanomaterial directly to the graphite fibre.

Yonex NAMD new carbon technology

In high performance racquets, it is common to combine nanomaterials with resin that connects graphite fibres, but in Namd, nanomaterials are directly adhered to the graphite fibres and the degree of adhesion between graphite fibres 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 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.

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.

Not bad, but I prefer the blue one. January 19, 2018
Reviewer: Robert S. from New Jersey  
Similar review to the one that I just placed on the Astrox 77 Metallic Blue. I bought both colors of Astrox 77 so it's not too boring using the same color all the time. Nevertheless, I find the Metallic Blue color works better for me since it has a head lighter feel in comparison to the Yellow one. I was able to swing and react faster with the blue one. I confirmed this with Badminton Alley customer service and they verified this; they performed a swing-weight test on them when about 4 rackets of each color from the batch they received using a specialized machine and found that all of the Yellow rackets has higher( or heavier) swing weight. Nevertheless, both rackets are excellent to play with.
