The YONEX Astrox 100 ZZ Badminton Racket stands out with its advanced engineering, making it a top choice for seasoned players. The racket boasts the slimmest shaft ever created by Yonex, allowing for reduced air resistance and swifter movements. Unlike traditional rackets with hollow cores, the Hyper Slim Shaft of the Astrox 100ZZ features a solid core graphite construction, enhancing resilience and power transfer.The Isometric frame design has been refined to provide an expanded sweet spot that is 2.9% larger than previous models, ensuring more effective hits. Additionally, the Energy Boost Cap at the top of the handle is redesigned to minimize shaft twisting and increase flexibility. This cap also offers a comfortable grip for players who position their thumb at the top while serving.Constructed with high-quality Namd graphite throughout the shaft and frame, this racket delivers increased flex and faster snapback, resulting in powerful and steep smashes. The material remains flexible even at high swing speeds, bending as the speed increases and swiftly returning to its original shape at the end of the swing. This dynamic bending and rapid recovery produce stronger shots and higher smash speeds.Key features of the YONEX Astrox 100 ZZ include:- Original US version by Yonex- Extra stiff flex- Frame made from HM Graphite, Namd, Tungsten, Black Micro Core, and NANOMETRIC- Shaft constructed from HM Graphite and Namd- Weight: Average 88g (3U)- Grip Size: G5- Color: Dark NavyThe YONEX Astrox 100 ZZ is ideal for adult advanced players looking to enhance their game with a racket that offers superior control, power, and precision.
