Leonardo da Vinci invented his flying machines watching birds and dragonflies.
Similarly, we took inspiration from nature to define the most efficient cross section ever used on a tennis racquet.
Bone is a complex structure built with composite material. This type of construction is the result of hundreds of million years of evolution and is optimized to withstand a remarkable combination of forces and torques.
SNAUWAERTECH BIONIC x-section adopts the bone-like design and is accurately shaped according to the frame local loads, always protruding towards the convex side of the frame and offering a higher resistance to bending and twisting forces.
In the frame head the bulkier part of the section faces towards the string bed area, in particular at 3/9 o’clock, increasing the lateral stiffness and offering a better ball control. In the flex point (5/7 o’clock) the section is symmetrical to better resist to the torsion.
Both GRINTA and VITAS frames features BIONIC x-section.
Tennis is an energy game. If the frames limits the string movement, part of the energy generated hitting the ball is absorbed by the frame into frame vibration, resulting in less ball velocity and spin.
SSG has a unique squared and tapered shape in the inner cavity of the grommet barrel, designed to maximize the string freedom at 360° in particular diagonally.
Differently from existing single dimension extended holes, the squared shape used for specific strings maximizes the string movement along the diagonal of a hole compared to the one of a round hole having the diameter equal to the side length of the squared.
The squared grommets have been used at 3/9 in the GRINTA frames to enhance the control and at 6/12 on the VITAS frames to enhance the power.
