A dynamic set of spin-enhancing grommets that work with the new spin boost string tech pattern to offer players more spin, power, and control. The new SX series features two more main strings than the current SX series. The grommets allow more string movement, which creates 'bite' on the ball, thus generating a spin rotation.  The extra movement makes the string bed more forgiving, effectively enlarging the sweet spot.

SPIN BOOST - String Tech

An innovative enlargement of the string bed creates more even power distribution and spin generation.


A unique V shape frame geometry in the shaft area of the racquet greatly enhances frame stability and racquet power.
