Dunlop Spin Boost Technology

SPIN BOOST technology is a dynamic set of spin-enhancing grommets that work with a dense, control-string pattern to increase the accuracy of shots hit with spin. Oblong-shaped, the grommets are located on the ten main strings at the top section of the racket hoop. This means more string movement that creates bite on the ball and generates mechanical rotation (spin) as well as making the string bed more forgiving, effectively enlarging the sweet spot.The result on off-centre shots at low impact locations on the string bed is 46% more string slide motion (compared with high impact locations), meaning more bite on the ball and more height and distance on shots. On off-centre high impact locations on the string bed the technology gives less string slide motion with less height and distance given to the ball.
