XXIO / ˈzɛk.si.oʊ /

Push Onward as the King & Queen of the 21st Century.

You haven't lost your golf. You've been playing with the wrong tools.
XXIO built the right ones — for you, from the first sketch.

The entire golf world builds clubs for professionals and hopes amateurs will keep up. XXIO did the opposite. They built some of the most advanced equipment, developed exclusively for swing speeds under 100 mph. The result? 20 consecutive years as Japan's best-selling brand.

The results speak

20 consecutive years as
Japan's best-selling brand.

The world's second-largest golf market. No other golf club series has dominated sales lists this long. Not Titleist. Not TaylorMade. Not Callaway.

20+

Years as #1 in Japan

Generations — each with longer carry than the previous

1909

Sumitomo Rubber Industries — 115 years of materials science

The problem nobody talks about

You lose about
1 mph per year.

After 50, most golfers lose about a mile per hour in swing speed — every year. Over ten years that's 10 mph. That's 25–30 meters of carry. That's the difference between reaching greens and not making it.

How the industry thinks

Built for pros.
Scaled down for you.

TaylorMade, Callaway, Titleist — all design first for Tour speeds over 115 mph. Then the technology is scaled down, becomes cheaper, shorter, and sold in pastels. They call it "ladies' clubs" or "senior shafts." In reality, they're compromises.

How XXIO thinks

Built for your body.
From the first sketch.

XXIO designs exclusively for swing speeds under 100 mph. Every component — from titanium to shaft to grip — is developed in-house to maximize speed with minimal effort. No downsizing. No compromise. Just physics working for you.

Your force profile determines — not your age.
Custom fitting for real.

A 65-year-old woman with 85 mph swing speed doesn't need a "ladies' club." She needs the shaft that matches her force signature. A 70-year-old man with limited thorax rotation doesn't need a stiffer shaft. He needs intervention first — then equipment. Data doesn't discriminate. Neither do we.

The Technology

Flight engineering. Tire research.
In your driver.

XXIO is owned by Sumitomo Rubber Industries — 115 years of materials science in tires, rubber, and metallurgy. The same researchers who minimize tire wear on asphalt optimize how titanium flexes at ball contact. It's not marketing. It's engineering.

ActivWing

Aerodynamic wing profile built into the club head crown. Taken from the aviation industry. Stabilizes the downswing, corrects club face angle, and prevents slice — without slowing speed.

Dual Speed Technology

Ultra-light shaft + concentrated mass in head. The physics is simple: speed squared beats mass. You swing faster with less effort — and the head hits like a sledge at impact.

Weight Plus

Counterweight at the end of the grip that moves the center of gravity closer to the hands. Reduces the force needed for the backswing. Guides the transition. The feeling: the club finds the right path by itself.

Rebound Frame

A spring within a spring. Six layers of stiff and flexible zones throughout the head. Result: 28% larger sweet spot and maximum energy return — even on off-center hits.

XXIO Weight Plus — counterweight in grip that guides your swing

The WAUW Feeling

The sound when the driver connects.
The ball that flies beyond all you believed.

There is a moment — right after impact — when your body knows before your mind. You hit it longer than you thought was possible. Not because you tried harder. But because the club finally worked with your physics, not against it. It is not just distance. It is proof that your ceiling isn't where you thought it was.

"I hit ten meters longer. But the strange thing was it felt like less effort — not more."

— WAUW client

Every new XXIO generation delivers measurably longer carry than the last. Not as a promise — as a requirement. If Gen 14 doesn't outperform Gen 13, it isn't released. That simple. That radical.

Three tiers.
Objective matching.

Your swing speed determines which XXIO is yours. We measure it on the force plates.

< 75

mph swing speed

XXIO Prime

The ultimate lightweight. Super-light SP-1300 shafts, maximum draw-bias, and the most forgiving profile in the portfolio. Gold accents. Functional luxury for the seasoned player.

75–90

mph swing speed

XXIO 14

The flagship. ActivWing, Weight Plus, Rebound Frame, VR-Titanium. High launch angle, forgiving, longer carry. The club that for 20 straight years has made Japan's number one.

85–100

mph swing speed

XXIO 14+

Tour feel without Tour weight. Carbon crown, stiffer shaft, adjustability. For you who've lost speed but refuse to compromise on control and appearance.

Why WAUW + XXIO

We measure which
XXIO is yours.

At WAUW Performance Lab we put you on Smart2Move 3D force plates, run TPI screening, analyze your swing in Sportsbox 3D AI, and verify with TrackMan. Then — not before — we match your force profile to XXIO's product portfolio.

The result: not the XXIO that looks best on the shelf, but the one that measurably gives you longer carry, better dispersion, and more joy. Every meter verified. Every choice based on your data.

That is the difference between buying a club and being fitted for one.
