Astrox 77 Overview:

Introducing the new Astrox 77 racquet 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.


Astrox 77 features NANOMETRIC:

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.

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 features NAMD:

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 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.
