The all-new badminton racquet by YONEX, the Voltric Z Force II Unstrung, is for advanced attacking players. YONEX Voltric Z Force 2 is one of the top picks among the top players in the world. Key Features: MAXIMUM ENERGY TRANSFER: The ultra-thin yet stiff shaft and ultra-aerodynamic head shape of YONEX Voltric Z Force 2 Badminton Racquet allow the shuttle to be hit with increased power, reducing the deceleration of the shuttle and allow it to be returned with sustained, ultimate power TUNGSTEN-INFUSED GROMMET: Tungsten-infused grommets of YONEX Voltric Z Force 2 Badminton Racquet maximize the contact time between shuttle and string. This, combined with the TRI-VOLTAGE SYSTEM, ensures that the frame flexes in a controlled way, holding the shuttle on the string bed for longer for maximum power transfer to the shuttle. AERODYNAMIC FRAME CONSTRUCTION: Air resistance is minimized by including the tip of the grommet inside the frame to produce an ultra-smooth, air-resistant shape that, together with a heavy head, delivers a smooth swinging frame with awesome power. EXTRA SLIM-SHAFT: Cutting-edge NANOMETRIC carbon technology produces an ultra-thin, ultra-tough, aerodynamic shaft created for stronger, more intense shots. AGILITY: The Control Support Cap provides an 88% wider flat surface than an ordinary racquet for easy gripping, fast swing-through, and the quickest manoeuvrability. Moving some of the weight at the top of the frame to the T-Joint area removes any unbalanced feeling while retaining flexibility at the head allows free and smooth handling. SOUND FILTER: Built into the YONEX Voltric Z Force 2 Badminton Racquet, a strong and powerful sound is created on impact, encouraging more aggressive play and making hitting more comfortable. BUILT-IN T-JOINT: Moulded deep into the layers of graphite where the frame connects with the shaft, the YONEX built-in T-Joint creates a durable and high-strength one-piece frame that is torque-free.
