PRODUCT SPEC Flex : Stiff Weight / Grip Size : 3UG5 (88g) / 4UG5 (83g) String tension : 3U:≦ 32 lbs (88g) 4U:≦ 31lbs (83g) 5U:≦ 30lbs (78g) Frame : High Resilience Modulus Graphite+HARD CORED TECHNOLOGY Shaft : High Resilient Modulus Graphite + PYROFIL + 6.6 SHAFT Balance : Head Heavy. TECHNOLOGIES Power Box - The box-shaped design effectively increases the stability and anti-torque, can stand higher string tension 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 SEVEN SIX - The single-pass grommet hole construction creates less friction between strings, this effectively reduces tension loss, while extending string life
