The F X series consists of five premium performance tennis rackets and is packed with technology. It is the first series to feature Dunlop's innovative POWER BOOST GROOVE technology, which provides players with a larger sweet spot, resulting in more power and allowing them to play with 'Power at Full Force'.
The F X series was thoroughly tested by our Dunlop Srixon engineers in Kobe, Japan, with the rackets achieving an average rebound of 4.8% across all impact positions compared to the same racket without GROOVE technology. The result is more power with greater consistency across the string bed.
“The F X series is the result of the tireless work of our global research and development team,” said Masahiro Asahino, Head of Tennis Division at SRI. “The end product is a series of power rackets designed for the modern game, where players benefit from improved consistency, control, and feel. Every player, regardless of skill level, strives for power, and that is exactly what this series delivers.”
By combining this new Power series with our existing series (SX - Spin, CX - Control), we now have a technically advanced racket for every type of playing style and skill level, which improves every game and helps to spread health and happiness through tennis.”.
The F X series also features four other key technologies that help deliver ultimate performance with consistency, feel, and forgiveness. These are:
POWER BOOST FRAME GEOMETRY : An aerodynamic head shape with a sharp, modern-looking shaft and a wider core for more stability, all working together to provide more power and stability during the swing.
FLEX-TOUCH RESIN: A completely new material with a unique, high-performance thermoplastic elastomer blend with high elasticity and vibration-damping properties, resulting in an improved playing feel.
SONIC CORE MADE WITH INFINERGY BY BASF : The FX series rackets also benefit from the use of BASF's Sonic Core made with Infinergy®, an innovative technology first introduced in the CX series. Infinergy® is the world's first E-TPU (expanded thermoplastic polyurethane) developed by BASF and is located in the 2 and 10 o'clock positions of the racket.
POWERGRID STRING TECH: The FX series also features the POWERGRID STRING TECH stringing technology from the CX series, characterized by a tight string pattern in the middle of the racket and a wider pattern in the upper part of the racket head. This technology ensures a more even distribution of force, especially in the upper part of the racket, which is increasingly used by the modern player.
The FX series follows the introduction of two additional product silos: the SX series, which focuses on providing players with more spin, and the CX series, which focuses on giving players more control. The name FX reflects Dunlop's new Elements of the Game , was developed for consumer understanding, and reflects the key benefits of each racket range: FX - Force, SX - Spin, CX - Control.
