WHAT IS SST PURE???
SST PURE® is a patented process of shaft alignment that analyzes a golf shaft to find its most stable orientation. Using proprietary patent-pending computer software and sensitive data-acquisition sensors, the SST PURE Shaft Alignment System quickly locates the “neutral” plane in each shaft. By assembling the club with the shaft in this SST PUREd position, off-line twisting and bending during the golf swing and at impact are greatly minimized. The SST PURE system also generates a printout for each shaft, showing its structural and performance analysis.

Why do shafts need to be PUREd?
Like snowflakes and fingerprints, no two golf shafts are exactly the same. Every shaft contains irregularities in straightness, roundness and stiffness that are inherent to the manufacturing process. These structural inconsistencies can negatively or positively affect a shaft’s performance depending on how the shaft is aligned in the clubhead. SST PURE locates the most stable orientation in any shaft.
The SST PURE process works on any shaft, regardless of its material; steel, graphite, even boron or thermoplastic shafts benefit from the SST PURE process.

What are the performance benefits of the SST PURE process?
The result of the SST PURE process is that players of all skill levels hit the ball longer, straighter and more uniformly consistent than ever before. Independent testing on players of all skill level has established that SST PURE improves impact repeatability on the center of the clubface by up to 51 percent. Clubs that have been PUREd have a softer feel than randomly installed shafts, which is the current standard for club assembly.

I just received my SST PUREd shafts. What is the correct way to install them?
On the butt of the shaft, there is a piece of tape with a line running down the length of the shaft. When you insert the shaft into the clubhead, the line should be pointing straight up. If you think of the hitting direction as 9 o’clock, this means you want the line at the 12 o’clock position.
For a left-handed golfer, however, you want the line in the 6 o’clock position.

What is the difference between spining and PUREing?
Spining is a nebulous terms that a lot of different people use to describe a lot of different processes. To some people spining means putting the shaft in a clamp and deflecting it back and forth. To others is means using a tube-like device to determine the straightness of a shaft.
The SST PURE process, on the other hand, is an engineeringly sound procedure that performs a structural and performance analysis on every shaft to locate its most stable orientation. This is done by computer analysis, so any errors which might be made from human judgment are negated. SST PURE locates the Plane of Uniform Repeatability in every shaft, that is, the dominant plane in the shaft on which the shaft flexes. This guarantees a softer feel and more consistent performance from club to club.
If any clubmaker tells you, "I can do the same thing as PUREing," don't listen to them unless you receive an official SST PURE printout. Your game is to important to be trusted to an individual's judgment.

Do steel shafts need to be PUREd?
Absolutely. Steel shafts are made by heating a flat piece of steel and wrapping it around a template called a mandrel. The ends of the steel are welded together to form what is called a weld seam. The location of this weld seam greatly affects the way the shaft performs. Straightness and roundness are also an issue in mass-produced steel golf shafts, and the SST PURE process takes all of these factors into account when PUREing a steel shaft.

Do PGA TOUR golfers use the SST PURE process?
The SST PURE Shaft Alignment Lab is present at many PGA TOUR events and has PUREd shafts for more than 200 TOUR players during the past five years. Some TOUR players will not hit a club unless it has been SST PURE aligned. Many players from the LPGA, Champions Tour and Nationwide Tour have also had shafts PUREd.

What does the printout mean?
The printout can be broken down into two sections: The top shows the results from a structural analysis of your shaft, and the bottom shows the results of a performance analysis before and after the shaft was PUREd.
The graph at the top of the page shows the results from the Load Symmetry Index Test. This test analyzes the structure of your shaft. The result is a number from 1 to 100. If a shaft were perfectly round, perfectly straight and equally stiff all the way around, its score would be 100 and the line on the graph would be straight across the top. Such a golf shaft does not exist.
The graphs at the bottom of the page indicate the movement of the shaft tip at impact. The red graph on the left demonstrates how the shaft performed in the Logo Up position, which is the typical method of shaft installation. The green graph on the right shows how the shaft performs in the SST PURE position.
Finally, the conclusion on the bottom of the page lets you know how much the shaft was rotated and how much more stable it is now that it has been SST PURE aligned.
