The Dunlop SX series

The SX is Dunlop's spin specialist — the line built for players who measure a good shot in revolutions per minute. The signature feature is an elliptical beam geometry called Spin Boost, which lets the strings deflect a touch more on contact and snap back into position with extra bite. Add to that an open string pattern and a lively response, and you get a frame that genuinely accesses heavy topspin with less effort than most rivals. It's a popular cross-shop with the Babolat Pure Aero — many players prefer the slightly softer feel of the SX.

Who it suits

The SX range covers everyone from advanced spin players (SX300 Tour, 305g) through to improving juniors and lighter-swing adults (SX300 Lite, 270g). The standard SX300 (300g) is the most popular all-rounder. If you're looking at heavy topspin frames more broadly, see our spin tennis racquets page or the Babolat Pure Aero.

Frequently asked questions

What is Dunlop's Spin Boost technology?
An elliptical cross-section beam that allows greater string movement on contact, helping the ball brush up the string bed for more topspin.

SX300 vs SX300 Tour — which should I pick?
The SX300 (300g, 100 sq in) is the all-court spin frame; the Tour (305g, 98 sq in) is heavier and more controlled, suited to advanced players.

Is the SX a good arm-friendly racquet?
It's softer than the Babolat Pure Aero but still a modern stiffness. Players with elbow concerns may prefer our arm-friendly tennis racquets shortlist.

What strings work best in the SX?
For maximum spin, a poly or hybrid is ideal. For comfort with spin, try a soft co-poly such as Babolat RPM Soft.

Do you ship Dunlop SX racquets pre-strung?
Yes — Lite and LS variants typically arrive pre-strung; Tour and base SX300 are usually unstrung but can be strung on request.
