Everything You Need to Know About SST PURE

Are Your Clubs PURE?

Despite being used by countless Tour pros and loads of custom club builders – including the world’s largest – SST PURE remains an unknown to many golfers.  That’s a shame, because it can make your clubs perform and feel better.  In this article, we’ll bring you the facts about this process so you can start PUREing your clubs and your shots.

“What is SST PURE?”

SST PURE is a process through which a club builder finds a shaft’s most stable bending plane or Neutral-Axis.  Said more plainly, it finds the correct way to install a shaft so that it bends in a stable, repeatable way.

Every shaft has imperfections.  Modern shafts are very good, but they will never be perfect.  As such, they are going to be stronger in certain spots, weaker in others.  SST PURE minimizes the effects of these imperfections by finding the best, most stable orientation.

“What are the benefits of SST PURE?”

Longer, straighter golf shots.  In a Golf Myths Unplugged test [read it HERE], we found a PURE’d shaft produced 7 yards more distance with a six iron as well as hitting shots 2.2 yards closer to the target line.

Additionally, PUREing helps you to swing the club faster and more consistently.  When the shaft is moving off-plane (not in the directions you intend), your body has to adjust and “fight” the shaft.  When the shaft is PUREd, moving only the intended directions, it speeds up and improves your swing.

PUREing also makes your clubs feel better.  In the aforementioned test, 6 out of 7 golfers were able to feel the difference between a PURE and un-PURE shaft.

“Is SST PURE only for driver shafts?”

No, every shaft can be PUREd – steel and graphite, driver through putter.  While some would argue that it makes the biggest difference in a driver shaft, an argument can be made for almost any club.  PUREing a putter shaft won’t drastically change your dispersion, but putting is a game of inches, and a perfectly installed shaft can make a measurable difference.

“Can you PURE an old (used) shaft?”

Yes, you can PURE any shaft.  If you’re using a shaft that you like, but want to get more out of it, a club builder with an SST PURE machine can remove the shaft, PURE it, and then re-install it in the correct orientation.

“What equipment is required for SST PURE?”

An SST PURE machine is required to perform SST PUREing.  There is no substitute.

“How is SST PURE different than spining or FLOing a shaft?”

SST Pure, spining, and FLOing all have the same goal – finding the best orientation of the golf shaft.  SST PUREing is simply a much more scientific, accurate way of achieving that goal.  It’s a bit like asking how is a Formula 1 race car different than a tricycle.  Both are ways to go from here to there, but one does the job on a very different level.

“How do you install an SST PURE’d shaft?”

When a shaft comes out of the SST PURE machine, it has a line on it (see the line on the tape above).  This line is installed straight up (think “logo up”) to orient the “strong” side toward the target.

There is an alternative called “Soft Side PUREing” where the strong side faces away from the target.  The benefits can be a softer feel and higher launch, but this method is the exception, not the rule.

“How does SST PURE work with adjustable hosels?”

The answer to this question varies based on which adjustable hosel system you use.

If your adjustable hosel system does not change the shaft’s orientation, there’s no issue at all.  You can install the shaft as you normally would, make adjustments, and the shaft will remain in the PURE position.

If your adjustable hosel system changes the orientation of the shaft, you will need to re-install your shaft if you decide on a new setting.  This is why it’s important in your fitting to nail down not only the right shaft and head but also the correct hosel setting.

  1. So if I have an existing set of irons how would I go about getting them PURE’d?

  2. A PGA Club Professional told me that puring only made a difference with faster swing speeds. Any thoughts on that? Thanks.

      Lee,

      I don’t agree with that. If you have the correct shaft for your swing, it’s going to flex. If it’s going to flex, you want it to flex in a consistent, predictable way.

      Best,

  3. I’m going to be honest, I’m surprised you believe in SST pure. It’s been debunked a lot and honestly, flies in the face of the manufactures that their quality control is not sufficient. The shaft market has stepped up their quality significantly and if there was any truth the the SST pure, spine, etc. “science” that would be an easy up charge that could come from the shaft companies themselves.

      Ramsey,

      We don’t “believe” in SST PURE – we’ve done our own testing and found it very impactful. With regard to it being “debunked” – where and by whom?

      Second, your claims about the manufacturers are poorly thought out. No one is arguing that shaft manufacturers don’t make high quality product, but, just as with anything, there are tolerances. SST takes something very good and makes it better. It’s no different than the fact that club OEMs have tolerances for lofts, lies, etc which is why golfers need club builders to check or perfect the builds. The reason that shaft manufacturers don’t PURE themselves is the same reason why club OEMs don’t offer “perfect spec” builds – it draws attention to the fact that not everything comes out of the factory 100% perfect.

    Matt, what are your thoughts on puring some of the newer graphite iron shafts? How do they compare with steel iron shafts in terms of minimizing dispersion by puring?

    • Matt Saternus

      Elliott,

      Interesting question. I don’t have any data on steel vs. graphite and how the PURE position relates to logo up or logo down, but that could make for a very interesting Golf Myths Unplugged. My general feeling, however, is that it’s worth PUREing everything.

      Best,

      Matt

  6. I had tried to post before but it never made it into the comments. Not everyone agrees with SST and the buyer should do research on their own. Russ Ryden is a club shaft guru and he thinks most shafts do not need this process and the extra cost associated with it.

    • Matt Saternus

      Chris,

      How do you suggest buyers “do their own research” – buy their own SST PURE machine and test dozens of shafts?
      With regard to Russ Ryden – what makes him a “shaft guru” above and beyond any other fitter and what testing does he have to show that SST is unnecessary?

      -Matt
