New for 2018, Head has updated the Radical range with an eye-catching colour scheme and now features its latest in materials technology – Graphene Touch . Graphene Touch adds a dampening material, called Kraibon to Head’s polarized weight system. The result is exceptional vibration dampening and easy power within the frame. With a 102″ head size and unstrung weight of 280g, the Radical S is lighter and more forgiving than the Radical MP and Pro. Like the previous generation, the Graphene Touch Radical S also comes with a Dynamic String Pattern which features tighter string spacing in the contact zone for more directional control.
