The Head Speed Elite offers tour-like qualities in a light weight frame. It features Head's YOUTEK technology that incorporates a new "smart material" into the frame called d3o. d3o is located in the shaft area where the racquet flexes the most and is able to sense the needs of the player during different strokes. On high impact strokes, the molecules lock together instantly to increase the stiffness of the racquet for more power. On slow speed strokes, the molecules absorb the impact to provide a softer touch for better feel. With d3o and Teflon Friction Reducing Polymer grommets, YOUTEK provides a perfect combination to match your individual needs. The Speed Elite offers excellent maneuverability and a medium beam for more power. Recommended for players with moderate to fast swing styles and for levels 3.5-5.5.
