The Dunlop CX 400 2027 is a lightweight 100 square inch racquet that brings the CX line's control-minded feel to a more accessible all-round package. It should suit a broad range of intermediate players, along with improving players who want easier manoeuvrability, controllable power and a smoother, more connected response than a traditional heavier control frame.
With its 100 square inch head, the CX 400 offers a more forgiving contact zone and easier depth than the smaller, thinner-beamed CX 200 models, while still aiming to keep the response predictable. The 16x19 string pattern helps the racquet deliver easier access to spin and a livelier launch than a denser pattern, which is useful for players who want help shaping the ball without overswinging. At 285 grams unstrung, it is easier to accelerate than the heavier CX frames, making it a sensible option for players still building strength or those who value quick handling from the baseline and at net. Its 330 mm, 4 point head-light balance is less head-light than the more traditional CX 200 models, which helps add some stability and support through contact without making the racquet feel cumbersome. The constant 24 mm beam also gives this model a firmer, more modern all-round profile, contributing some accessible pace compared with the thinner-beamed control models in the family.
For 2027, Dunlop's main change is a revised stiffness distribution through the hoop rather than a simple cosmetic refresh. The upper hoop is designed to flex inward a little more for better ball feedback, while the lower part of the hoop is firmed up to improve torsional stability and help the racquet feel steadier when contact is not perfectly clean. Sonic Core has also been repositioned to 3 and 9 o'clock, where it works with Vibroshield to reduce unwanted vibrations and create a smoother, more comfortable feel. Control Frame Geometry is intended to reinforce stability through the face and throat, while Powergrid Stringtech+ refines the central 16x19 string bed to encourage string movement for usable spin and pace.
The CX 400 2027 fills an important role in the CX range by offering a lighter, more forgiving route into the series' control-oriented identity. For players who want a racquet that is easier to swing than the CX 200 models but still designed to feel composed and connected, it is a worthwhile option.
-
Sonic Core: Located in the middle of the hoop, this super-elastic, super-light material, offers rebound properties significantly higher than other materials. Reduced vibrations mean reduced impact and more comfort.
-
Vibroshield: Feel the control when hitting. The high elasticity properties of the vibration dampening material within the racquet frame reduce vibrations and gives an increased feeling of control when hitting.
-
Control Frame Geometry: Improved stability, and greater spin and power. Advancements to the frame shape provide improved stability in the face and throat of the racquet. And more vertical string length means increased string movement for greater spin and power.
-
Powergrid Stringtech+: Hit with increased spin and power. The updated string pattern enables increased spin and power in the central hitting area.
Photos used contain images of strings for illustration purposes. Adult tennis racquets are unstrung unless otherwise noted or stringing services have been selected above. Brand logo stencils are not applied by default with stringing services. If you request brand logo stencils, please note that a stencil is painted onto the strings within a brand's stencil and may wear off over time - this is how stencils are applied on tour. Depending on the string you select, the stencil paint application fullness, colour and visibility may vary.
Adult racquets generally do not come with covers. To protect your racquet, we recommend getting a racquet bag.
Product specs such as weight may vary slightly from racquet to racquet to what is advertised due to the manufacturing process.
