Fast just got easier to handle thanks to the SPEED MP LITE. It features the Graphene 360+ technology, a combination of Graphene 360's energy transfer and innovative spiralfibers for an enhanced flex and clean impact feel as well as a 16/19 string pattern for the right amount of spin. The MP Lite features the silo's new design with an asymmetric combination of matte and glossy white and glossy black. The Speed Series is endorsed by Novak Djokovic.
