The Sx gets updated for 2022 which gets a new cosmetic look with new technology pieces. The new Sx series delivers even more spin, on those off-center shots giving players more confidence to hit harder and really target those court lines. More spin with more speed with a higher launch angle all equals to visibly more spin from the Sx racquets. Dunlop has implemented all new SPIN BOOST + grommets into the 2022 Sx racquet series. Dunlop adds a dynamic set of spin-enhancing grommets that work with a new spin boost string tech pattern to offer more spin, power and control. Dunlop has defined the shape of the grommets located on the 12 mains through the top section of the racquet hoop which is 2 more than the previous generation. This allows more string movement which helps create more bite on the ball. Dunlop continues the use of SONIC CORE technology within the Sx frames which is located at the 2 & 10 o'clock portions of the racquet. Made with Infinergy by BASF which is a world's first E-TPU developed by BASF. Dunlop has designed the string bed to create more power distribution thanks to SPIN BOOST technology. Dunlop's V ENERGY shaft greatly enhances frame stability and racquet power thanks to its unique V-shape frame geometry in the shaft area. The Sx 300 Tour is a spin and control oriented racquet that, based on the weight of the racquet, generates a lot of power in combination with a high level of spin. The Sx 300 Tour is perfect for players who hit the ball with a longer styled swing path who like to generate high-power levels in their hits and need control to hit with a higher amount of spin.
