More precise weight distribution throughout the grip end, frame top and the joint increases the rotational power. These enhancements ensure the momentum for quicker consecutive shots. Namd*1, which produces more flex and a faster snapback, is used throughout the frame and shaft, unleashing dramatic steep power. The synergy created from the Rotational Generator System enables continuous powerful attacks.
The already slim shaft has been modified utilizing a high-quality graphite material, creating the slimmest shaft*2 to date in Yonex. It provides a smoother follow-through by reducing air resistance and generates rotational power through more flex and a faster snapback.
The original ISOMETRIC frame has also evolved into a more ISOMETRIC shape, expanding the sweet spot. Designed for reduced power loss from off-center shots, the 2.9% larger sweet spot increases power.
*1 Namd is a technology developed by Nitta Corporation to “uniformly disperse carbon nanotubes into carbon fiber composites”.
*2 Hyper Slim Shaft in ASTROX 100 ZZ
Common technologies throughout the ASTROX 100 series.
1. Expanded Sweet Spot in Modified Frame
Compared to regular round frames, Yonex’s original ISOMETRIC frame creates a wider sweet spot. The ASTROX 100 frame has been slightly modified into an even more square-like shape, increasing the already wide sweet spot by 2.9%*1, while maintaining the same overall frame size. Benefits of this evolved ISOMETRIC shape include increased power on strong and continuous shots even if they don’t hit the center of the racquet.
2. Newly Designed Cap: E.B.CAP PLUS
A new structure reduces shaft twisting and increases its flexibility. Thumb fitting shape transmits even more power to the shuttle.
Differences between the ASTROX 100 ZZ and the ASTROX 100 ZX models.
3. Advanced Rotational Generator System
The new innovative Rotational Generator System precisely distributes weight to the top of the frame, joints, and the end of the racquet grip.
In ASTROX 100 ZZ, Black Micro Core material at the top of the frame increases rigidity by 4% and vibration absorption by 2%*1. While the use of Black Micro Core material puts more weight on the head of the frame. A new built-in T-joint, which is 1.3%*1 lighter than any other Yonex racquet, allows the racquet to have a lower weight distribution. By redesigning the racquet’s weight distribution in this manner, high rotational power needed for strong continuous smashes is generated.
4. Improved Swing-ability and Resilience: Slim Shaft
ASTROX 100 ZZ : Hyper Slim Shaft
Designed with the slimmest shaft in the history of Yonex racquets*1, this ASTROX model, traditionally hollow inside, uses graphite material in the core, resulting in an 11.8%*1 reduction in air resistance. By making the shaft solid, resilience is increased, further allowing strong continuous shots.
ASTROX 100 ZX: Extra Slim and Rexis Shaft
Rexis is a high-performance shaft precisely designed through an advanced molding technique with High-Quality, ingenuitive, Performance Graphite material. It has surpassed Yonex’s quality standards.
5. Revolutionary New Graphite Namd
By utilizing high quality Namd graphite throughout the shaft and frame of both models more flex is produced with a faster snapback, unleashing dramatic steep power. The material stays flexible even with increased swing speed, bending when swing speed increases and restoring its original hard shape at the end of the swing. The ability to bend even further and snap back rapidly, produces stronger shots and greater smash speeds.
Viktor AXELSEN (Denmark), CHOU Tien Chen (Taiwan), Akane YAMAGUCHI (Japan) and other #TeamYonex athletes will make their debut using the new ASTROX 100 ZZ during the 2020 season.
