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 Grommet Pattern
The single-pass grommet hole construction provides more grommet holes for a more high-performance stringing pattern.
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.
Combines solid hitting feel and quick swing.
Rotational Generator System
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 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.
Touch G Fiber
“TOUGH G FIBER” is a mixture of Carbon Nanotube and Glass Fiber which has approximately 3 times the elasticity of conventional material. This new technology is utilized in the frame of “ASTROX 66” to enhance flexibility and maximize repulsion power which provides a soft shot feeling and increases the flight distance of the shuttle. This badminton racquet delivers the shuttle to the back of the court creating further advantage in the game.
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.
Control Support Cap
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.
