Yonex Nanoray Z-Speed Badminton Racquet The latest head-light series from Yonex,The Nanoray Z-Speed racquet provides a fast and controlled swing with enhanced repulsion via the New Aero Frame. Nanoray is designed for players who force their opponents into the back of the court with extreme speed. 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. We only carry 3ug4 grip size but can special order other grip sizes Technologies: SBZ (SNAP BACK ZONE): The unique frame design of the NANORAY Z-SPEED means that the frame is thinner at the midway point at either side of the racquet head. At this point, EX-HMG, the most elastic and powerful material ever, is used within the frame, allowing it to flex on impact and repel the shuttle with explosive acceleration and devastating power. Swing Speed increased by 10%: Every element of this racquet has been designed to increase swing speed. A new frame cross section and ULTRA SLIM LONG SHAFT, together with cutting edge materials NANOMETRIC* and X-FULLERENE, make the NANORAY Z-SPEED the most aerodynamic racquet that YONEX has ever produced. NANOMETRIC*: improves the bonding strength between the carbon fibres enabling us to take racquet shaft construction to another level. By reducing the amount of carbon in the shaft to make it 60%* thinner than a conventional racquet whilst retaining stiffness, YONEX has created a revolutionary lightweight racquet with lightening head speed and control. X-Fullerene: The new generation X-Fullerene has 4 radial ribs which unite carbon atoms to form a football-like structure. The X-Fullerene is used in the resin which bonds the carbon fibres and creates the cross-link construction. The tenfold increase in binding force makes it possible to create 5% higher repulsion power and 15% greater stability. Flex:Stiff Frame:H.M. Graphite, SONIC METAL, EX-HMG Shaft:H.M.
