If your game is fast as lightning, the SPEED PRO can give you the control you need. Recommended by Novak Djokovic, the PRO comes with the Graphene 360+ technology, a combination of Graphene 360's energy transfer and innovative spiral fibers for an enhanced flex and clean impact feel as well as an 18/20 string pattern for high control no matter how fast the game. The PRO is available in a new design with an asymmetric combination of matte and glossy white and glossy black.
