Dunlop SX 300

The Dunlop SX 300 is an explosive, spin-oriented performance racket designed for aggressive players who want maximum topspin potential and power from the baseline. The SX designation stands for Spin and Experience — and the SX 300 delivers both through a combination of Dunlop’s Spin Boost Grommet system, the open 16×19 string pattern, and the aerodynamically optimized frame profile designed to increase racket head speed through the hitting zone. Dunlop’s Spin Boost Grommet system uses specially shaped grommets that deflect during ball contact, allowing strings to move more aggressively before snapping back to their original position — creating a slingshot effect that significantly increases topspin generation on every groundstroke. The Aeroskin CF2 surface texture applied to the beam further enhances aerodynamics, reducing drag and allowing faster swing speeds that directly translate to more power and spin. At 300 grams strung with a 100 square inch head size, the SX 300 is both accessible in weight and confident in performance. The vibrant yellow and black cosmetic design echoes the racket’s aggressive, energetic playing character. The SX 300 is particularly effective for players who like to construct points from the baseline using heavy topspin to push opponents back and create offensive opportunities. If your game centers on topspin aggression and powerful groundstrokes, the Dunlop SX 300 is purpose-built for your style.
