Brand new to Yonex is the Nanoray range of rackets, Overwhelm opponents with even faster shot-making and greater repulsion power. With HM graphite and Fullerene in the frame - Fullerene is equipped into the lower sides of the frame to deliver high elasticity and stiffness for exhilarating, sharp repulsion. In synergy with increased stiffness from the new Aero Frame shape, the 700RP generates exceptional drive shots. The secret behind NANORAY's exceptional performance is a unique head construction featuring YONEX's new Aero Frame structure where the frame sides vary in thickness between the top and bottom of the head. The thinner top of the frame sides minimize air resistance for greater head speed, while the thicker sides at the bottom of the head generate maximum repulsion through greater frame stiffness. Incorporating X-Fullerene into the whole shaft strengthens the binding force, increasing stiffness by 6% and repulsion power by 4%. This combination delivers high repulsion performance to hit deep into the opponent's court even with a compact swing during high speed rallies. Lightning fast shot-making with high repulsion is generated by near-instant 'snap back' from the shaft during the swing. Isometric square head shape - Developed by Yonex, the Isometric Square Head Shape provides a 32% larger effective hitting area than a conventional racquet. Unlike an ordinary racquet, whose main and cross strings vary in length, the Isometric Square Head Shape equalises the length of main and cross strings in the string bed and enlarges the 'sweet spot' for more consistent shot accuracy - even on off-centre hits. The new lightweight Built-in T-Joint is made from an epoxy resin material that enhances your level of performance by increasing the stability of the shuttle on the string bed and through the air. The new Yonex single-pass grommet hole construction provides more grommet holes at the 2 & 10 o'clock position on the frame, creating a high performance stringing pattern that increases durability by 7%.
