The Head Speed Pro is the latest racquet of choice for Novak Djokovic and makes use of new Head technologies such as d3o and DuPont Teflon grommets in a player-oriented package. A 98 square inch head, thin 18mm beam, leather grip and 12.4 oz. strung weight add up to a very control and feel oriented stick for those players advanced enough to wield it. A more open 16x19 string pattern than Head typically has offered in its players frames makes the Speed Pro more spin friendly for topspin players. Head introduces d3o technology in the Head Speed Pro, and is a "smart" material in that it behaves differently under varying dynamic loading or impact. Integrated in the frame lay-up and positioned in the shaft area (where the racquet flexes the most), d3o seeks to help players maximize performance on all shots. High speed impacts lock d3o together within nanoseconds at the molecular level, stiffening the frame to provide maximum power. Conversely, on slower speed impacts, the d3o molecules absorb the impact providing softer touch for better feel. The Speed Pro also uses a DuPont Teflon grommet system that reduces friction. Less friction means maintaining more of the strings energy, and a resulting slight increase in power.
