The Equipment Behind an Elite Doubles Player

Seo Seung Jae is one of the most accomplished doubles specialists of his generation, competing at the highest level in both men's doubles and mixed doubles for Korea. Players like him attract equipment questions constantly, because fans reasonably assume that if a world-class athlete chooses a particular frame, it must be exceptional. He is a sponsored athlete on the Victor roster, and he plays with Victor frames from their attacking range, most commonly associated with the Thruster family of rackets that the brand markets toward aggressive, power-oriented play.

The important caveat is that professional racket setups change between seasons, and sponsored players frequently use custom or pre-release specifications that differ from the retail version sharing the same name. Grip build-up, string choice and tension are also personalised to a degree that makes the retail frame only a rough approximation of what is actually in the athlete's hand. Treat the model name as a starting point rather than a formula.

How AAMAX.CO Helps Sports and Gear Sites Grow

Why an Attacking Frame Suits His Style

To understand the setup, look at the role. In men's doubles, Seo Seung Jae operates in a system built on rapid rotation, flat drives, aggressive net play and finishing rallies quickly. That style asks specific things of a racket. It needs enough head weight to generate steep, heavy smashes from the rear court, but it also needs to be manoeuvrable enough to handle fast exchanges at the net where reaction time is measured in fractions of a second.

Attacking frames like the Thruster line are designed around that compromise, typically with a head-heavy or even balance, a stiffer shaft that transfers energy efficiently for players with fast swing speeds, and a compact head shape that cuts through the air. A stiff shaft is unforgiving: it rewards clean technique and precise timing and punishes late or lazy swings. That is exactly the right trade for a professional and exactly the wrong trade for most recreational players.

Strings and Tension Matter More Than the Frame

Club players obsess over frames and underestimate strings, which is backwards. Professionals commonly play thin gauge strings, often in the 0.66 to 0.68 millimetre range, at tensions substantially higher than retail defaults, frequently in the high twenties to low thirties in pounds. High tension gives a flatter trajectory, better control on fast flat exchanges and a crisper feel, at the cost of a smaller sweet spot, less power assistance and faster breakage.

Copying professional tension is the most common equipment mistake in the sport. At high tension, the string bed does less work, so the player must supply more racket speed. If your swing speed cannot generate that, you lose power, gain arm strain and get worse results than you would with a moderate tension. Most club players are better served in the low to mid twenties, with grip size and weight tuned to comfort rather than imitation.

What Club Players Should Actually Copy

Copy the intent rather than the specification. If you play attacking doubles from the rear court, a slightly head-heavy frame will help you generate steeper smashes. If you play the front court in a rotational system, prioritise a lighter, more even-balanced frame that lets you react and block quickly. If you play singles, favour balance and control over raw power, because rally length and consistency decide matches.

Shaft flexibility deserves more attention than brand. Medium or flexible shafts store and release energy for slower swing speeds, effectively adding power for most amateurs, while stiff shafts only pay off above a certain swing velocity. Getting this one variable right will improve your game more than switching to any professional's exact model.

Why Player Gear Questions Drive So Much Search Traffic

Equipment searches sit at a rare intersection of fandom and purchase intent. Someone typing a player's name plus racket is either about to buy or about to research a purchase seriously. For retailers and content publishers, these queries convert at rates that generic category pages cannot match, which makes them worth targeting individually rather than lumping into a catalogue page.

The winning content format is consistent: name the setup clearly, explain the specification in plain terms, state honestly what is known versus assumed, then help the reader decide whether it suits them. Pair each player page with comparison content, skill-level buying guides and string tension explainers, all internally linked. Add a broader digital marketing layer with tournament-timed campaigns and email capture, and seasonal spikes turn into a returning audience. Because AI assistants now field a large share of these factual gear questions, structuring answers to be quotable matters too, which is where our GEO services keep brands visible.

Conclusion

Seo Seung Jae plays with Victor equipment from the brand's attacking range, most commonly linked to the Thruster series, strung thin and tight in the way elite doubles players generally prefer. Specifics shift by season and are customised beyond retail specification, so treat any exact model claim as approximate.

More useful than copying his racket is understanding why it suits him and choosing a frame that suits you. And if you run a site that answers questions like this one, we can help you turn that curiosity into rankings and sales.
