Racket Response Indicator：
A new Speed racket engineered with the advanced Twin Epoxy Resin System (TERS), JS-12 comes with stiff frame and resilient shaft, offering easy controllability for net shots and massive force for sweeping movement, most suitable for fast players.
The single-pass grommet hole construction creates less friction between strings, this effectively reduces tension loss, while extending string life.
Innovative technology combining the two popular frame structure SWORD and AERODYNAMIC, the AERO-SWORD can efficiently reduce air resistance and allowing a faster and greater hitback.
PYROFIL carbon fiber and its composites, are advanced high-performance materials from Japan. The characteristic of high intensity bonds ultra-light offer racket excellent shock-absorption and enhance handling in every single game.
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.
Engineered with US-imported aerospace-level materials, the Twin Epoxy Resin System (TERS) stiffens the frame further, provides the best elasticity, and achieve holeless compact structure through automatic ventilation. TERS enables efficient force transmission and keeps amazingly stable and sturdy controllability during fast attack and defend.
