ArcSaber racquet is designed to store up energy during the shot, allowing you to attack with pinpoint accuracy. For players seeking a higher lever of control. Yonex ArcSaber 002 extending the top of the frame increases the sweetspot for acute angle shots. NanoAir Spring: By introducing Nanoair Spring into the resin which binds the carbon fibres, nanoscale air bubbles in the material help the racquet to flex and bend as in a spring. The result is a better transfer of energy from string-bed to shuttle for a more powerful hit. Isometric: Developed by Yonex, the Isometric Square Head Shape provides a 32% larger effective hitting area than a conventional racquet. The Isometric Square Head Shape equalizes the length of main and cross strings in the stringbed, enlarging the sweetspot for more consistent accuracy even on off-center hits. Build-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. Control Support Cap: The Control Support Cap provides an 88% wider flat surface compared with an ordinary racquet for easier gripping, fast follow-through and the sharpest manoeuvrability.
