The new Metallic Carbon Fibers are embedded in the frame using Dynamic-Sword technology, which offers better aerodynamics and consequently faster swing. The Nano Fortify TR+ and Rebound shield technology, together with a classic wooden handle, give the racket a unique feel while improving serve speed and increasing smashing power.
To improve speed while maintaining a lighter weight, the ARS-90-K is designed with NANO FORTIFY TR to keep the frame lightweight and durable.
In the new edition, it uses WES technology, which employs a softer material in a specific portion of the handle near the neck to increase the head speed of the racket and enable true “whip” effects for faster and more aggressive shots, while also increasing the attacking angle, which becomes even sharper.
The racket is suitable for players who have fast, dynamic, and extremely attacking play.

technology improves the racket frame. The racket frame features an inward-facing cut structure oriented towards the 6 and 12 o'clock positions (on the racket head) and an outward-facing cut structure oriented towards the 3 and 9 o'clock positions, designed to mimic the aerodynamics of a sword. That way each swing is fast and sharp.

This system copies actions of the whip and because of that has a built-in softer material in a specific place of the frame near the neck of the racket. This improves the acceleration speed of the racket’s head and enables the "whip" effect, so you can create faster and more powerful offensive attacks, while also keeping a good amount of control.

Introduction of the METALLIC CARBON FIBER (metal + carbon fibers) into the racket’s construction ensures a unique and elastic feeling and an incomparable feel at impact.
Technology RTC is a structure that originates from a scientific design, developed with data analysis. This technology introduces a "responsive point" at key points of the frame, so you can achieve the best quality of the rebound, which then increases the quality and the speed of the strike.


Pyrofil- high-quality and ultra-light carbon fibers from Japan- offer great dampening of vibrations and improve play characteristics.

:
Based on Nano Fortify TR material. Nano Fortify TR + is designed with advanced carbon fibers, that are more solid and more durable, so they guarantee durability and a comfortable feeling.
:
Sonic-Rebound integrates RTC technology with graphite materials. That offers more resilience, with the goal, of allowing you an optimal and fast rebound, which newly identifies “fast” rackets.

Smaller shaft flex is key to optimized power transfer.
:
String layout with 76 holes (grommet holes). That means less friction between strings, Which decreases tension loss and lengthens the strings lifespan.
