Designed to provide control over every aspect of the game, the Dunlop CX 400 Tour features a host of modern technologies to improve feel, accuracy, and comfort.The main new addition for this third generation of the CX is FLEX BOOSTER, a vibration-dampening material integrated into the shaft. Combining with the absorption properties of SONICCORE – the rebound-enhancing tech in the sides of the racket head – FLEX BOOSTER makes the racket easy to handle, offering pinpoint sensory information and long-lasting comfort.Elsewhere, POWERGRID string tech returns, utilising wider crosses at the top of the stringbed to create a larger sweetspot for greater control over off-centre hits. No holding back here – wield the CX with confidence and you’ll be rewarded tenfold.Featuring a classic boxy beam, the CX 400 Tour has the same control-focused design as other rackets in the series, but with a slightly stiffer feel and thicker beam for easier access to power. Its 100 sq in headsize and 300g unstrung weight make it the ideal choice for intermediate and experienced players looking to switch to a control-based frame.Please note this racket will come strung unless the image displays otherwise.

• Headsize: 645 sq cm / 100 sq in
• Weight (Unstrung): 300g / 10.6oz
• Balance (Unstrung): 320mm

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.
