The Head Graphene 360+ Speed MP Black Tennis Racquets are loaded with an array of new updates from Head Tennis. Starting with the Head implementing “Graphene 360+” into the Speed MP with the combination of Head’s signature Graphene 360 technology for optimized energy transfer and the innovative “spiral fibers” for enhanced flex & a clean impact feel. The Speed MP comes with Head’s “Superactive stringbed” in which Head has widened the cross-strings adding power and spin to your game. The Speed MP comes with a dynamic frame construction — built for increased speed. The strong shaft and shoulder area allows for increased stability and that solid feel and sound.
