Swing DNA - Shaft Optimisation

Find the perfectly matched shaft in 3 swings

"A player can go to any of Mizuno's Fitting centres around the country and be fit to the perfect shaft within 15 minutes. The fitter can apply their skills to the more constant components - length, lie angle, grip size, knowing that our Fitting System will look after the engine of the club - the shaft."

Swing DNA - What's the blueprint?

The Mizuno Club Fitting Workshop

Just ten years ago the most complex shaft choice a serious golfer had to make was 'Stiff or regular?' Now the massive growth of custom fitting has thrown up so many options that the average player has more ways to get it wrong than ever.

Faced with this problem, Mizuno has developed a cutting edge technology that takes shaft fitting to a whole new level. In creating Swing DNA a unique system that identifies the unique blueprint in every swing - Mizuno has addressed the most critical element of the entire custom fitting process.

Specially-created software sifts through the mass of shaft options to select the optimal match, based on Swing DNA recorded by Mizuno's Shaft Optimiser. What was once a time-consuming and inaccurate process is now one that is immediate, consistent and widely available.

• Clubhead Speed
  • How fast the clubhead and shaft are moving during the swing.
• Tempo
  • How quickly the player transitions from the backswing to the downswing.
• Shaft Toe Down
  • A measure of the bowing of the shaft in a downward directtion during the downswing.
• Shaft Kick Angle
  • The amount of shaft forward bending during the downswing motion.
• Release Factor
  • How and when the clubhead and shaft are releasing during the downswing.

Shaft Optimisation

On traditional custom built sets shaft recommendations were based on the theory that fast swingers required stiff s, while everybody else was a regular. Twenty years on, the Mizuno range of custom iron shafts has evolved to more than 50 options, with only a few State of the Art Facilities able to take advantage.

Mizuno's new Shaft Optimiser changes everything. A real golf club with specially developed strain gauges and microprocessor, the Shaft Optimiser records an individuals Swing DNA from just 3 real shots. Combined with an exclusive Mizuno software the unique DNA is used to narrow down a baffling prospect of more than 50 shafts to the very best match - with 2 back up suggestions to test against.

The Shaft Optimiser is unique in the amount of information it records. Clubhead speed and tempo might typically determine the ideal flex and weight of the shaft, but with so many variables to consider - weight, flex, kick point, tip softness - much more hard data is required to accurately determine a player's optimimum shaft. The Shaft Optimiser also measures shaft toe down, shaft kick angle and release factor readings in order to build up the players unique blueprint.

Be fit to the perfect shaft within 15 minutes.

"Identifying the complete Swing DNA Blueprint is hugely important because two players with identical speeds can need completely different shafts to maximise their flight. Players who release the club early, for example, need a different bending profile to those who favour a late hit. Their swing speeds might be the same, they might even need the same flex, but fi tting them for the same shaft could be disastrous."

Theory vs. Reality

Mizuno's process incorporates an interchangeable shaft system so that the recommended shaft / head combination can be tested as confirmation.

Offering a choice of head weights - standard, lighter and graphite-weighted each test iron is designed to feel and play exactly like Mizuno's final production models. To ensure that the extra weight of the specially-made titanium adaptor didn't impact on the club's playing properties, 8 grams of mass was removed from the hosel of the test head. Any combination of shaft and head screwed together during the fitting process, will have the weight, feel and performance of a final production iron
