The HEAD YouTek Graphene Instinct Jr. Tennis Racket comes with new Graphen technology to bring your game to the next level. Youngsters won"t be short of inspiration on court knowing they"re playing with the junior version of Maria Sharapova"s and Tomas Berdych"s weapon.Graphene is the world"s strongest and lightest material. It consists of a single two-dimensional layer of carbon atoms. Graphene technology allows for the optimal redistribution of weight in HEAD racquets. Through the use of Graphene in the shaft, the weight in the middle part of the tennis racquet can be reduced. Instead, weight can be shifted from the racquet shaft to more functionally relevant areas in the tip and grip. This unique construction provides players with an unmatched manoeuvrability and an increased swing weight. In other words, a racquet with Graphene is easier to swing and enables even more powerful shots.YouTek combines superior technologies to perfectly match your individual needs. Whether your game is aggressive and adventurous or consistent and smooth, YouTek enhances your performance and brings out the best in you.This racket features D3O technology. Integrated into the lay-up and positioned in the shaft of the racket, this is essentially material that changes its behaviour and adapts to different strokes during play for the best results. Aggressive shots come with a high-speed impact and so the molecules lock together and increase stiffness, thus providing more power. Upon the impact of slower shots the molecules absorb the impact and add a softer touch for better feel. If you think quickly and make sharp decisions, this racket will be with you every step of the way.The racket also includes Innegra hybrid-composite structure. This tough fibre is the lightest performance fibre in the world and reduces the amount of vibrations upon impact for better stability, in the long term this
