Dunlop SX 300 Tour 2025

The Dunlop SX series has been upgraded with advanced technologies and a refreshed cosmetic design; this 300 Tour variant is suitable for advanced players who need their racquet to deliver huge spin and power on their biggest swings.

The 98-square-inch headsize is slightly smaller than average, offering a tighter sweet spot that enhances precision while demanding greater effort for increased power, making it ideal for players who can handle the challenge. The open string pattern delivers a lively response with easier spin access. As the heaviest model in the SX series at 10.8 ounces (unstrung), it provides additional stability, plow-through, and stopping power, enhancing the potential for powerful returns and heavy spin for those with a controlled full swing. Its head-light balance (unstrung) improves manoeuvrability, crucial for generating power, executing quick net play, and enabling faster swings for increased spin production. The beam thickness further optimises frame stability, improving energy transfer and power across the string bed, a feature commonly seen in modern racquets designed for spin and power.

The SX series features advanced technologies designed to enhance performance. The Spin Boost XT Grommet Technology increases grommet hole size by 58% at the 6 o’clock position, allowing greater string movement for improved spin, working alongside angled grommets at the 12 o’clock position for better control. The Spin Boost Frame Geometry increases frame width by 8% at the 3 and 9 o’clock positions, minimizing frame rotation for greater stability, while enhanced stiffness in the face and throat reduces deformation, boosting ball speed and spin. Additionally, Vibroshield Technology, a highly elastic material placed at key points, reduces frame vibrations by 30%, ensuring enhanced comfort during play.

Combined with its core technologies, enhancements, and specifications, this racquet becomes a formidable tool for players seeking to maximise power and spin.

• SPIN BOOST XT: Dunlop has increased the size of the grommet holes at the 6 o’clock position by 58% which allow more string movement for increased spin potential. This technology works in tandem with the existing angled grommets in the 12 o’clock position which deliver increased spin and control.
• SPIN BOOST FRAME: The frame width has been increased by 8% in the 3 & 9 o’clock positions which increases the stability of the racquet by minimizing frame rotation on impact. Spin Boost Frame Geometry allows you to strike more confidently knowing the racquet will be stable even on off center hits.
• Vibroshield: Vibroshield is a highly elastic material that reduces frame vibrations by 30% compared with the previous SX models which enhances overall comfort of the racquets. The Vibroshield material has been incorporated to the 3 & 9 position as well as the throat area to maximize its effect.
• SPIN BOOST FRAME: The frame stiffness in the face and throat of the racquet has been increased which results in less frame deformation on impact and in turn increases the ball speed and spin off the strings.

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.
