Dunlop SX 300 Tennis Racquet Unstrung

The Dunlop SX 300 is the flagship of Dunlop’s spin-focused SX series a racquet built from the ground up to maximise topspin production for players who make spin the foundation of their game. The open 16×15 string pattern is rarer in performance racquets and creates dramatically more string movement at contact, biting into the ball and generating the kind of heavy, kicking topspin that pushes opponents back behind the baseline.

The aerodynamic beam profile reduces air resistance through the swing zone, enabling faster racquet-head acceleration that directly translates to more revolutions per second on the ball. The Spin Boost Grommet system in the frame further enhances string movement, amplifying topspin production beyond what the string pattern alone achieves.

At 300g unstrung and 100 sq in, the SX 300 is manoeuvrable enough for rapid swing acceleration while providing the mass needed to generate pace through a spin-heavy stroke a combination that produces groundstrokes with both serious RPM and the depth to be genuinely dangerous in rallies.

This is the choice for advanced club and competitive players who want to dominate from the baseline with heavy topspin, particularly on high-bounce courts. Available in grip size G2. Recommended stringing tension: 45-55 lbs.
