Yonex Nanoflare 170 Light (Black-Blue) Badminton Racket 5U4 – Sonic Flare System ? gives improved shot speeds by positioning high modulus graphite at the top and bottom of the frame. H.M. Graphite is utilized on the top of the frame with results in improved repulsion performance. Torayca is utilized at the bottom of the frame which greatly improves the stability of the frame and the repulsion performance of the racket. New Aero Deformation Frame ? when a shuttle is hit, the force on the strings causes frame deformation. The frame then returns to its original shape with its stiffness. The force provided by the frame deformation reduces stress and increases the distance the shuttle travels. Please note, where applicable, we will relogo the strings on rackets which have been restrung.
