Version · 23 optionsSX 300 Tour 2025Change

The 2025 SX 300 Tour is the heavier, more precise version of Dunlop's spin line. It weighs 305 g unstrung (323 g strung) and has a 98 in² head, an open 16x19 pattern and a 23/26/23 mm beam, wider on the sides since the 2025 version for more stability. With a swingweight of 321, a balance of 6 points toward the handle and 69 RA, the racquet accelerates quickly and produces heavy topspin balls with good power. The Vibroshield in the handle helps with comfort, but the response remains firm.

The RR Score is not yet a precise figure. It summarizes the data we have today (specs and reviews) and changes as more information comes in. A low score does not mean the racquet is bad and does not reflect its technical quality: often it is just missing data or reviews. The specs combine several sources and may have discrepancies: check the manufacturer's website and the store where you buy.
