Dunlop SX 300 Tour

Tie your opponent up in knots with the Dunlop SX 300 Tour tennis racket in Yellow/Black, featuring Spin Boost+ technology for additional power and spin potential.
Spin’s a formidable weapon in itself, but combined with raw power, it’s devastating. Featuring Dunlop’s new Spin Boost+ grommets, the Dunlop SX 300 Tour allows you to play with both power and spin, giving you more options and limiting your opponent’s as you constrict them into submission.

Upgraded for 2022, Spin Boost+’s strategically shaped grommets allow more string movement in specific directions on 12 of the main strings at the top of the hoop (look closely and you’ll see the arrows on the frame to demonstrate), creating increased “bite” on the ball and thus producing more rotation. It’s not just spin either – by restricting the movement of the strings to certain directions, the technology helps you maintain control of your shots for greater accuracy. The new model also features slightly wider spacing of the grommets, forming a larger string grid area to deliver maximum spin even if you connect off-centre.

Now boasting a 98in headsize, the SX 300 Tour nonetheless remains the heaviest racket in the SX range and is chiefly aimed at experienced players with a fair amount of arm strength. If you can handle it, though, the rewards are huge: massive built-in power potential and shock-absorbing comfort thanks to the sheer amount of mass, along with accurate feel and control courtesy of a mixed-width beam and slightly lower stiffness rating. Add all of that to the racket’s outrageous spin-generation capabilities, and the Tour edition of SX 300 stands out as one of the best all-round rackets in the game today.


British stalwarts Dunlop possess one of the most recognisable logos in the game: the energetic “Flying D” has flashed through the air at tennis courts around the world since the 1960s. But their history goes back much further. All the way to 1888 and founder John Boyd Dunlop’s invention of the rubber pneumatic tyre for bicycles, a revolutionary development with all kinds of applications.

A few decades later, having initially entered the world of sport by producing rubber golf balls, Dunlop turned to tennis, using their expertise in vulcanisation to create some of the first “modern” tennis balls in 1923.

Then came the rackets. Or, more specifically, then came the Maxply. First introduced in 1932, the legendary wooden frame dominated the professional game for the next 50 years. Rod Laver wielded it to win both of his calendar year Grand Slams in the 60s, and it was in the hands of John McEnroe as he secured his Wimbledon and US Open double in 1981. After the Maxply came the carbon fibre Max 150G, and then the 200G – the racket Steffi Graf used to win the Golden Slam in 1988.

Dunlop’s focus extends beyond the pro game, though. In fact, their mission is to share the joy of tennis, giving every player the chance to enjoy the process of getting better, bit by bit, whatever your level.

Following that ethos, their modern range is clearly defined and easy to choose from. You’ve got the CX series for control, the FX for power, and the SX for spin, all available in a selection of weights and headsizes, of course.

Spin Racket

Spin rackets typically have open string patterns – fewer strings with more space between them – to allow the strings more “bite” on the ball and make it easier to produce spin. They often have specially designed grommets that increase the effect, along with aerodynamic frames for faster racket speed through the air.
