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 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.Sitting at the heavier end of the spectrum, the 300 gram version of the SX 300 is ideal for intermediate and advanced players with a fair amount of arm strength. It retains the same stiffness rating as the heavier Tour racket at 64 RA, making this a great option if you prefer the feel of a more flexible racket but want to stick to a slightly lighter weight.

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.
