The Yonex Astrox 100 ZZ 3U4 is a professional badminton racket aimed at advanced players seeking relentless attacking potential, superior precision & incredible consistency achieved through remarkable stability of the frame. The racquet is endorsed by the Japanese badminton prodigy Akane Yamaguchi, & takes advantage of the Black Micro Core technology to ensure maximum smoothness & vibration dampening properties as well as a stiffer feel. Furthermore, the racket features a revolutionary lightweight Nanometric material to create a much thinner cross-section without losing the stiffness while adding a tremendous amount of speed to each stroke. Enhanced power potential of this head heavy balanced racket comes mostly from the Namd graphite material which improves bonding between fibres to enhance the energy transfer & turn it into explosive power on rebounds. The racquet offers a larger sweet spot with an isometric style head & it's shipped pre-strung with BG65 Ti string.
