TECHNOLOGY

AUXETIC
Auxetic constructions show a unique deformation compared to non-Auxetic constructions. Due to their internal properties, Auxetic constructions widen when a “pull” force is applied and contract when squeezed. The bigger the applied force, the bigger the Auxetic reaction.
SPIN SHAFT
The spin shaft provides optimized lateral stability, creating higher spin potential
SPIN PATTERN
The open 16/19 string pattern maximizes string snap-back for greater spin generation
SOUND GROMMETS
Sound grommets provide enhanced power via greater string movement and optimize sound and vibrations
SPIN GROMMENTS
Spin grommets allow for greater main string movement in all directions for maximizing power and spin.
