XXIO Lightness for Stronger Swings Bringing lightweight golf club design to the player's category, X enhances speed and distance for mid to low handicap golfers. X takes all our accomplishments in lightweight club design and presents them in a better player's form-factor.

The XXIO brand takes its name from the Roman numeral for 21 (XXI) and the letter O, which is both Japanese for “king” and short for ON (as in “Onward”). Thus, XXIO means “Push Onward as the King of the 21st Century!”

Owned by the same company as Srixon and Cleveland, XXIO are a Japanese golf manufacturer which offers a wide range of equipment from metalwoods and irons to golf balls and accessories. XXIO place a premium on creating products with a lightweight design geared towards more moderate swing speeds.

XXIO 12 Driver It's no different than many parts of high-end cars because these vehicles have features not found in other cars and since the features require specific parts and there are fewer of these cars made, the end result is a higher cost to ensure quality is maintained through the process.

The new XXIO Prime driver is meant to be a premium investment for seasoned, moderate swing speed golfers a straighter, longer ball flight. Though it may carry a hefty price tag, it's a high quality golf club for the mortal golfer.

LTD (a subsidiary of Japan's Sumitomo Rubber Industries – the SRI in Srixon – and the parent company of Srixon, Cleveland and XXIO) says in its annual report the overall golf market in North America actually grew last year. So not only did Cleveland/Srixon not get its share of that growth, it actually lost ground.

XXIO Prime Irons bring together advanced ball speed technologies and exotic, remarkably lightweight materials to improve distance and straight ball flight, while neutralizing swing fatigue caused by heavier Irons.

Srixon focuses on golf, with its balls holding the largest number of patents worldwide, and having previously supplied other leading manufacturers such as Dunlop Slazenger. They also produce a full range of golf clubs and accessories. In October 2007, SRI Sports acquired Cleveland Golf.

Most golfers would be absolutely shocked to see how much a shaft deforms during the swing in terms of Ovaling, Twisting, Kicking, and Drooping. The premium shafts significantly eliminate these effects because of their stronger and more stable material/design yet provide exceptional feedback and performance.

There are general rules all fitters use: (1) A lighter shaft will be easier to swing faster and is likely to launch the ball higher. But it's best to match your strength to shaft weight. (2) A more flexible tip section compared to the butt section likely will launch the ball higher.

Stiff flex shafts are less flexible and better suited for golfers with faster swing speeds - typically around 90 to 105 mph. Regular flex shafts, on the other hand, are more flexible and can accommodate golfers with average swing speeds - roughly between 80 and 95 mph.

If you have a fast swing, a stiff flex may be the right choice for you. However, if you have an average swing speed and could use a little help with distance, a regular flex shaft could be a better fit. Test your swing with different shaft flexes to find the one that works best for your game.
