Graphene is Heads breakthrough technology. This material is the ultimate material for creating a new HEAD racquet frame with a 200 times breaking strength of steel and has exceptional properties. For the first time, you can redistribute the perfect weight from tip to grip. It allows for redistribution of weight compared to traditional frames, removing weight from the center and adding weight up and down to increase motor energy as a player hits the ball. This design allows you to produce lighter weight and less labor. Heads Corrugated Technology CT2 features an extra-long corrugated rail for exceptional power per shot. The Heads YouTek racquet series is designed with d3oTM smart materials that adapt to your play style. Powerful shots are more explosive and touch shots are more accurate. Special d3o material hardens and improves the power of hard shots, softer with slow slice shots, and more feel.
