The Vertex 04 racket, official racket of the Premier Mexico tournament, comes with a neoprene cover. It is a diamond-shaped racket with maximum power and a rough Top Spin surface. It is designed for professional or advanced players. It incorporates two new concepts in the frame, the CURVAKTIV system: Its twisted structure provides additional resistance to twisting. Thanks to the twisting of its faces, it allows us to introduce a variable section on the side of the racket. We manage to introduce a smaller section than that of the vertex03 frame, increasing rigidity, but we also manage to widen the section along its length, achieving a more uniform transmission of stresses throughout the blade. This better distribution of vibrations and stresses is also supported by the combination of the CURVAKTIV with the AIR POWER. AIR POWER is the natural evolution of the Air React Channel system. It is a channel that we generate through a hollow piece on the lower side of the blade. This hollow piece works better than if it were a solid piece because it is made up of less material and is less prone to deformation, making the structure stronger. The outer core is made of Xtend Carbon 12K carbon, the inner core is made of the new MultiEva rubber and the inner core is made of 100% carbon fibre CarbonTube. It has the Custom Weight weight plate system allowing the balance of the racket to be modified according to the needs of each player. It has the Vibradrive system for vibration absorption. It also incorporates the Hesacore grip, which reduces stress, vibrations and the likelihood of injury.
