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 310g allows you to play with both power and spin, giving you more options and limiting your opponent’s as you constrict them into submission. A new introduction for the SX range, Spin Boost’s oblong-shaped grommets allow more string movement in specific directions on the main 10 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. As the heaviest racket in the SX range, the SX 300 Tour 310g 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. Please note this racket will come strung unless the image displays otherwise.

Measuring Your Grip Size

Choosing the right grip size is a vital part of playing tennis. The right grip size will make your racket feel natural and comfortable.

Use a ruler and measure (in inches) from the crease fold in your hand, to the top of your ring finger. Please see table below:

Grip Size
USA (inches)
4 1/8
4 2/8
4 3/8
4 4/8
4 5/8

Note: It is always better to go for a smaller grip size, as you can easily increase your grip size with over grips.
