The Head Graphene Touch Speed MP adaptive tennis racket is a customisable frame that belongs to the Speed range endorsed by a star player Novak Djokovic & has been designed for advanced & intermediate level players. The racket is head light balanced, therefore grants more mobility, speed & enhanced handling, & with Graphene Touch technology it's capable of producing fantastic shot sensation with a dampened feel on top of that. Furthermore, the frame can be modified in multiple ways with Head's Adaptive Tuning Kit (32 tuning possibilities in total). Starting from grommet sets, you can switch to another stringing pattern easily e.g. from a heavier one to a light, more spin-friendly option. The length of the frame is customisable with three spacer rings (5, 10 & 15mm) & the end cap can be replaced with a heavier one to ensure a more balanced feel of the racket. By default, the racket is shipped strung with Lynx 17 string in a light 16x 19 string pattern, & fitted with Hydrosorb grip to provide enhanced comfort & moisture absorption.
