The Yonex Nanoray 20 Badminton Racket comes with Isometric technology which equalizes the length of the main and cross strings in the string bed, enlarging the sweet spot for improved accuracy. The control support cap provides an 88% wider flat surface compared with an ordinary racquet for easier gripping, fast follow-through and the sharpest maneuverability. Aerodynamic contouring of the top of the frame minimizes air resistance so air flows faster across the curved surface during the swing, accelerating head speed and transferring more speed and power into hits.
