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 effectively reducing tension loss while extending string durability.
Innovative technology combining the two popular frame structures SWORD and AERODYNAMIC, the AERO-SWORD can efficiently reduce air resistance while allowing a faster and greater hitback
Engineered with US-imported aerospace-level materials, the Twin Epoxy Resin System (TERS) stiffens the frame further, provides the best elasticity and achieves holeless compact structure through automatic ventilation. TERS enables efficient force transmission and keeps amazingly stable and sturdy controllability during fast attacks and defence.
