Solid feel impact for smash-based hitters looking for more power and durability. Made with the newest technology and with X-Fullerene. X-Fullerene provides more repulsion power and frame stability than Fullerene. Yonex developed the new generation Fullerene which has 4 radial ribs by manipulating Fullerene molecules to unite carbon atoms into a soccer ball structure. The X-Fullerene is used in the resin which bonds the Carbon Fibers and creates the cross-link construction. The ten-fold increase in binding force made it possible to create 5% higher repulsion power and 15% greater stability. Comes in Metal Orange.
YONEX Nanoscience achieves the quickest of racquet work two ways; first, by providing sensitive control of how racquet materials perform at the level of a thousand millionth of a particle unit, and second, by reducing the amount of racquet material the shaft needs, for the ideal super-thin/ high-strength ratio.
NANOSPEED 9900 TYPE X FEATURES:
NANOSCIENCE: Yonex Nanoscience achieves precise control over racquet functions at the molecular level. It establishes a high-performance molecular bond of the fullerene and carbon nano-particles, creating an ultra-lightweight racquet that's thinner, stronger and more stable than an ordinary racquet for maximum power and speed from swing energy.
X-FULLERENE: X-Fullerene is used in the resin which bonds the Carbon fibres and creating the cross-link construction. The tenfold increase in binding force makes it possible to create 5% higher repulsion and 15% greater stability.
NEW GROMMET SYSTEM: The single-pass grommet hole construction provides more grommet holes, creating a high-performance stringing pattern that puts 7% more durability.
MUSCLE POWER: Muscle Power sets the string on rounded archways that eliminate stress-load and fatigue through contact friction. The construction creates total unity of the string and frame through closer-and-tighter contact.
NANOSCALE ELASTIC TI: Elastic Ti provides the high elasticity needed for structural high strength and a powerful rebound effect. At impact, Elastic Ti resists deformation, stretching then recovering its shape quickly to launch accurate hits charged with the full energy of the swing.
ISOMETRIC: The 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-center hits.
BUILT IN T-JOINT: Moulded deep into the layers of graphite where the frame connects with the shaft, the Yonex built-in T-Joint creates a durable and high-strength one-piece frame that is torque-free.
