Description:Yonex has taken the Nanospeed Series to the next level by developing ‘X-Fullerene’, a new Nanoscale material designed to enable an even faster and more powerful game. X-fullerene has made it possible for Yonex to create a thinner and stronger head-light racket while maintaining great manoeuvrability and repulsion power. The new built in T-Joint enhances performance by increasing the stability of the shuttle on the string bed and through the air. 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-centre hits.
