As the world number 1 in badminton, Yonex has always been in the forefront of innovations that push the boundaries of what can be achieved on court. With levels of speed in the game continuing to increase, Yonex has now 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 racquet while maintaining great manoeuvrability and repulsion power. X Fullerene has four radial ribs which unite the carbon atoms into a unique soccer ball structure. The X Fullerene sits within a resin which bonds carbon fibres to create a cross link consruction. This translates to a 5% increase in repulsion power and 15% greater stability. With single pass grommet system creating a high performance stringing pattern that increases durability by 7%. Built in T joint for strength. LSC system to raise comfort and improve shock resistence. Buy this racket and receive a Free Karkal LG Grip.
