JS-7 is an easy-to-use, All-AROUND-inclined SPEED racket for badminton lovers of all ages. With JS-7, every shot can be both fast and accurate.
The NANO TEC technology works by evenly distributing nano-sized particles in the vacant space between carbon fiber bundles, this highly increases the overall stiffness of the carbon composite fibers, and reduces the distortion of the frame.
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 offers racket excellent shock-absorption and enhances control.
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.
