Yonex - Astrox 100 ZZ Kurenai AX100ZZ Made In Japan Badminton Racket (4U-G5)

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. 

Namd 

Astrox 100 ZZ uses NAMD in its entire frame from head to body of racket.

NAMD is world’s-first, new dimension graphite material which greatly improves the adhesion of the graphite fibers and resin by attaching nano material directly to the graphite fiber. This in turn helps double up contact time with the shuttle, resulting in explosive shots as the racket returns from flexed to straight at the end of the swing, this happens instantly.

In high performance rackets, 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.

Hyper Slim Shaft 6.2mm

Yonex's slimmest shaft ever features a solid core with revolutionary material. Namd provides greater flex and strapback performance at the same time reduces air resistance for faster swings. Designed to slice through the air, generating speedy power

Energy Boost Cap/PLUS

Uniquely shaped cap which maximizes shaft performance. The front allows the shaft to flex, while the sides arch-shaped curve stabilizes the racket face by preventing the shaft from twisting. This design ensures the maximum effect of “Namd (more flex and faster kick-back graphite material)” to increase control.

Isometric
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.

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 NANOALLOY^TM Technology of Toray Industries, Inc.

Black Micro Core

Used for the first time in Yonex badminton rackets, BLACK MICRO CORE is a stiff, high-density vibration-dampening material equipped into the upper part of the racket frame, letting players hit with solid feeling and power.
