The Head Graphene XT Speed Pro tennis racket, endorsed by Novak Djokovic, is the heaviest version in this Tour range & offers good manoeuvrability & stability despite the heavier weight. Created for intermediate to advanced players, the Speed Pro racquet delivers control & feel, thanks in part to the 18x 20 string pattern. The racket uses Head's latest Graphene XT technology to strengthen the frame & distribute weight more efficiently to the tip & handle. The racket swings very easily & smoothly, & has a 100in 2 (645cm 2) head so good pace can be developed on shots. The racket comes with a Hydrosorb Pro grip which is tacky & sweat absorbent.
