One day, your game will be as fast as lightening - just like Novak's. Until then, the Speed Jr, gives you the same benefits of the grown-up Speed series inn a lighter and easier-to-handle version. Made for the serious newcomer, the racket features the new Graphene 360+ technology, a combination of Graphene 360's energy transfer and innovative spiralfibers for an enhanced flex and clean impact feel. While the 16x19 string pattern and new grommets ensure improved playability, the new design identity scores with an asymmetric combination of matte white and glossy black.
