The SPEED PRO model is created for the advanced tournament player who needs more control for their fast-paced game. The new Graphene 360 technology provides greater stability and optimized energy transfer for more power, thus more ball speed. The 18/20 string pattern provides higher control during even the fastest rallies. The SPEED silo follows the new asymmetric design identity, featuring a bold black and white color-blocking in the shaft area. Completed by truly unique see-through carbon fibers in the head, the racquet looks as beautiful as it performs. The Speed Series is endorsed by Novak Djokovic and Sascha Zverev.
