The HEAD GrapheneXT speed MP restrung tennis racquet was first introduced in 2014. HEAD constructed the speed MP with graphite and graphene XT technology. The latter removes weight away from the shaft and toward the grip and the top of the racquet. The result is more ball speed at impact and more stability due to the increase in swing weight. The speed MP has a fast-feeling 22-millimeter beam 100 square inch head and spin-friendly 16×19 string pattern. With an unstrung weight of 10.6 ounces the racquet remains mobile yet stable enough for bigger hitters. The GrapheneXT Speed MP comes pre-strung with synthetic gut 16g at 57 pounds.
