Stiffness : S○○○ ●F
Weight / Grip Size: 4U / G5
String tension LBS : 4U:≤32 lbs(14.5Kg)
Frame Material: Graphite+Resin+Fiber Reinforced System(FRS)
Shaft Material: Graphite+Resin+7.0 SHAFT
TECHNOLOGIES:The single-pass grommet hole construction creates less friction between strings, this effectively reduces tension loss, while extending string life.
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.
