The single-pass grommet hole design decreases friction between strings, reducing tension loss and prolonging string life. The advanced Fiber Reinforced System (FRS) is constructed with a multi-layered carbon fiber and increases elasticity while allowing high tension string control.

The ULTRA-THIN FRAME is 7% thinner than traditional rackets to increase swing speed, yet retains stiffness and anti-torsion performance. The compound frame consists of a fan-shaped upper section which reduces wind resistance, a compound-sword middle section to lighten filler and allow rapid rebound, and an airfoil lower section that further lowers wind resistance for ‘whipping’ style strikes with excellent control.
