The concave aerodynamic racket head has an enlarged sweet spot. Easy handling and impressive dynamics an ideal racket for the ambitious offensive players. Nano-Eplon is a three-dimensional, nano-meter carbon mesh. This mesh is one of the stiffest materials ever built. One of the most distinguished qualities is the extreme loss-free impulse transfer and stability. Nano-Eplon technology from OLIVER ensures the perfect combination of lightness, stability and power. The new 3D- Mesh is set in the sweetspot-zone, to enlarge the torsional rigidity and to advance the power. The metacarbon and graphite lay-ups will be strengthened, without an increasing of weight. With Metacarbon, a fibre developed by OLIVER, enlarges the kilopond- pressure per mm², 4 times more than titan. Now, its possible to decrease the frame-density and to ensure a longer durableness. Even though Metacarbon has a fundamental stiffness, the connection with HSM-Resin ensures a extraordinary expansibility.The usage of Metacarbon makes a reduction of the weight possible. The Metacarbon-rackets offer an optimal comfort, handling and vibration cushoning. The Metacarbon makes a dynamic and explosive game possible due to the improved power transmission, weight-reduction, and durability. Graphite is a carbon fibre, which is produced through an oxidation of polyacrylnitril fibre. Graphite is 40 % lighter than glass fibre and additionally five times stiffer and has a two times more rupture power. Highmodulus Graphite (T700) is finer than normal graphite and is produced by heating. The Highmodulus Graphite (T700) offers a higher hardness grade at the same weight. It’s the optimal material for High-Impact sport devices. The concave system ensures more power due to its specialised concave construction. The concave frame profile in the inner of the racket-head stretches the side-length and enlarges the sweetspot up to 8%.
