Product Details
JS-12 II is designed with a lightweight 6.6mm shaft, which is 8% lighter than the previous 6.8mm shaft and also reduces the wind resistance by 2.9%. The strength of the frame is also improved by 17.5% with the help from NANOFORTIFY TR+ material.
The material property of PYROFIL greatly enhances the overall elasticity. What’s more, the FREECORE synthetic handle technology is integrated into the high-end Speed series racket for the very first time, making the hitting more stable and comfortable.
JS-12 II has an eye-catching painting, matches perfectly with the streamline watermark sticker, and even delivers a stronger sense of speed. The style setting of “easy swinging and comfortable hitting” further makes it a distinctive Speed racket. Having been through years of growth and evolution, as well as the integration of material and technology, JS-12 II not only bears the spirit of speed, but also ignites our inner passion!
Technologies
FREE CORE
Designed by computer simulation and aided with the adoption of injection moulding technique, this revolutionized handle style allows the shaft to move more freely, which can not only make swings smoother but also improve overall handling experience.
REBOUND SHIELD
Introducing highly resilient and durable glass fiber into the multilayered design of the frame to provide better elasticity and comfort during hitting.
NANO FORTIFY TR+
Built on the strengths of the NANO FORTIFY TR, the NANO FORTIFY TR+ is engineered with an advanced, more durable carbon-fiber that is firm but offers pleasing resilience and hand-feel.
PYROFIL
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.
Hard Cored Technology
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.
AERO-SWORD
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.
Seven-Six76
The single-pass grommet hole construction creates less friction between strings, this effectively reduces tension loss, while extending string life.
