Version · 23 optionsSX 300 2025Change

The 2025 SX 300 is Dunlop's spin-and-power racquet. It weighs 300 g unstrung and has a 100 in² head, a 16x19 pattern, a 23/26/23 mm beam, a swingweight of 318 and 69 RA. For 2025 it gets a new mold, with a wider frame on the sides for more stability and energy transfer, Vibroshield in the heart and head against vibration, and more open Spin Boost XT grommets in the throat, which let the strings move more and increase spin.

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.
