The Yonex NanoRay Speed (NRSP) Iron Gray badminton racket is a lower price racket based on Yonex top-of-the-line NanoRay Z-Speed (NRZS). The racket is suited for intermediate and advanced players who want fast swing and precision control through its Compact Frame, a smaller frame size further reduces unwanted air resistance and improves feel. The Nanoray Speed (NRSP) also uses unique frame design called Snap Back Zone (SBZ) where the frame is thinner at the midway point at either side of the racket head. At this point, specialized material is used within the frame, allowing it to flex on impact and repel the shuttle with explosive acceleration and devastating power.

The Yonex NanoRay Speed (NRSP) badminton racket also uses the new Horizontal-A concept grommet pattern that helped create one of the smallest frame in Yonex's history. The pattern anchors 4 strings horizontally to allow greater flex in the string bed and to create an enlarged sweet spot at the top of the frame. So even off-center shots can be powerful.
