The single-pass grommet hole construction creates less friction between strings, this effectively reduces tension loss, while extending string life.
Inspired by military helicopter, multi-layered structure made by carbon fiber and composites, minimize material size, reinforce handling feel and performance at a critical standard.
The Rebound Transition Construction, with science-tested “Rebound Points” on specific parts of the racket frame, increases the rebound of the racket to produce more weight and velocity in your strokes.
The Sonic Rebound Technology integrates Rebound Transition Construction and a high-resilience carbon fiber material, maximizing the rebound effect upon impact to help you strike with that extra speed like you never experienced before.
The compound frame design can be divided into three major parts: The upper section is made with fan-shaped structure to lower wind resistance and accelerate each swing. The Compound-Sword structure in the middle section is designed to lighten the filler and enable fast rebound. Finally, the lower section is built in airfoil structure to lower wind resistance and keep excellent anti-torsion performance in a 'whipping' style which helps to create steeper and quicker attacks with satisfying control.
