SST Pure: A deep dive into the technology
Due to the manufacturing process, all golf shafts contain irregularities in straightness, stiffness, and roundness. And depending on how a shaft is aligned, the inconsistencies can adversely affect a shaft’s performance and consistency.
SST PURE was developed as a solution to this problem.
In simplest terms, the SST PURE (stands for it stands for Plane of Uniform REpeatability) process finds a shaft’s most stable orientation to minimizing twisting and off-line bending during the swing. This results in longer, straighter ball flight and more consistent performance in all PUREd shafts. Subjectively, PUREd shafts are often described as feeling “softer” than their non-PUREd counterparts.
For more background on SST PURE and PUREing on tour, we talked with SST founder Dick Weiss, independent rep Scott Garrison, who has the only SST Pure machine on a tour truck, and rep Arnie Cunningham.
Here’s what they had to say.
SST founder Dick Weiss
GolfWRX: Give us a 101-level overview of SST PUREing.
DW: What we do at SST is we analyze the irregularities in a shaft and based on various algorithms, various mathematic formulas, determine which is most asymmetric. Which is the one that’s causing the shaft to bend and twist out of line at impact and also in the first load – the transition between backswing and downswing, there’s a lot of movement in there also. What we do is identify that and mark it so it can be assembled into the club head.
It’s a technological development. It’s come about because we have computers today to do this. We don’t do it by eyeball. The computer doesn’t care who’s going to play it, what level of skill they have, what the material composition is of a shaft, who made it, what kind of ball you’re going to hit. That’s not what we do. What we are saying is we want to analyze a shaft to get it to perform to the best of its ability. You can take a shaft based upon irregularities in it – because shafts are not round or straight.
If you take any shaft and roll it on a table like a pool cue, you’ll see 90% of the time they’ll bounce along because they’re not round. There’s high points and low points, thicker and thinner areas. All we want to do is locate that and say, “Let’s make it work as an asset, let’s make it work as a support for a shaft so they don’t torque out or twist out at impact.”
GolfWRX: Can you give us a brief overview of exactly what goes on in the SST PUREing process?
DW: Sure. In the PUREing process, there’s approximately fifty-six steps you have to take assuming you do what we call a retro-PURE. There’s two ways to PURE. One is if you take a brand new head, a brand new shaft, PURE the shaft and assemble it into a head – that’s a brand new club. The second way would be what we call a retro-PURE. One is we take apart an existing club, keep the shaft, take the grip off, peel the tape off underneath the grip. We use our Weiss-Gibson Ultimate Extractor, we cut the ferrule off. We remove the shaft. We drill out the old epoxy in the head and acetone the head down. We then drill out any old epoxy that may be in the tip of the club. We turn down and clean the outside tip of the club if there’s any epoxy or residue from the epoxy itself where the ferrule may have been. We then go ahead and PURE the shaft. We come back and fit a ferrule, reassemble the club. We use a fast dry epoxy with shafting beads in it.
GolfWRX: Now what would you say to those who don’t believe in the SST PUREing process?
DW: In any technology, people question it which is good. People still don’t think the Earth is round. I think if they are honest with themselves – forget about Dick Weiss and SST as an entity. If they’re honest with themselves and they know anything about clubs whether they make them in their garage or professionally, they have to be able to tell that shafts can not perform the same just randomly or haphazardly assembled. Each shaft has its idiosyncrasies.
So I say for the ones that don’t believe in it, do a test yourself without any type of process. Take a club out, hit it, bring it back in, try to stay off the quadrants, 90 degrees left, 180, another 90, that’s not the way to do it. Move it 30 degrees to the left or right. Put it back in and go hit it. Flip the plane upside down, put it back in, and go hit it.
We’ve started doing a lot of internal testing is because everyone says, “Let us see some independent testing.” We said okay and did it. We took the tour van and five workers with us. We used clubs I hadn’t seen. They came from tour. We didn’t look for asymmetric products. We just took what was there, new shafts, new heads, some of the heads I’ve never seen before. It doesn’t make any difference. We’re happy to subject it to any tests.
Scott E Garrison
“Studies have shown the irregularities in shafts, and that causes offline shots. If you play pool at a bar, you’re going to take the straightest queue.”
GolfWRX: How do you showcase the benefits of SST PUREing when players visit your truck?
SEG: When I have a player in the truck, and I do a quick demonstration and put a shaft in the machine, within two minutes, they’re in…they’re hooked.
All the OEMs, they’re seeing their players want this done, so we’re PUREing up shafts and getting them back to [their trucks] so they can build PUREd clubs for their players.
GolfWRX: What performance examples can you give us where a player PUREd his shafts and saw tremendous improvement?
SEG: It was about seven years ago when I just finished re-gripping Ben Martin’s putter with a SuperStroke grip. As he was leaving, I asked him if he had ever had his clubs PUREd. He said, “No, but I had heard about it and was curious.” I showed him a set I was in the middle of PUREing and he was sold. It was Monday morning, the week of the RBC Heritage and it was pouring. He said to PURE his entire set. That’s what I did Monday afternoon. I ripped his gamers apart and PUREd the shafts and put them back together (a retro-PURE). He was leading the tournament, he shot a career-low round and finished third. He told me later how much better his mis-hits were.
Arnie Cunningham
GolfWRX: What’s the most obvious benefit of PUREing?
AC: It’s about dispersion patterns. Until a person can really dive deep into the numbers—and we’ve done it throughout the years at Golf Laboratories and its proved over and over that the dispersion pattern is better PUREd vs not.
GolfWRX: Are there any misconceptions about PUREing?
AC: Detractors might be looking for some miracle feel, but really, it’s about the dispersion and an improvement on the already good technology in shafts.
GolfWRX: Tell us about the USGA restrictions on PUREing.
AC: You’re stabilizing the golf shaft. You’re putting it in the best playing position possible. If you PURE a shaft, by USGA rules, you can not turn that shaft to allow for a draw or a cut. Just that rule tells me they know it works because they’ve tested and they’ve seen the difference in performance.

Spotted: Tommy Fleetwood’s TaylorMade Spider Tour X Prototype putter
Tommy Fleetwood has been attached to his Odyssey White Hot Pro #3 putter for years now. However, this week at the Wells Fargo Championship, we did spot him testing a new putter that is very different, yet somewhat similar, to his current gamer.
This new putter is a TaylorMade Spider Tour X head but with a brand new neck we haven’t seen on a Spider before. A flow neck is attached to the Spider head and gives the putter about a 1/2 shaft offset. This style neck will usually increase the toe hang of the putter and we can guess it gets the putter close to his White Hot Pro #3.
Another interesting design is that lack of TaylorMade’s True Path alignment on the top of the putter. Instead of the large white center stripe, Tommy’s Spider just has a very short white site line milled into it. As with his Odyssey, Tommy seems to be a fan of soft inserts and this Spider prototype looks to have the TPU Pure Roll insert with 45° grooves for immediate topspin and less hopping and skidding.
The sole is interesting as well in that the rear weights don’t look to be interchangeable and are recessed deep into the ports. This setup could be used to push the CG forward in the putter for a more blade-like feel during the stroke, like TaylorMade did with the Spider X Proto Scottie Scheffler tested out.
Tommy’s putter is finished off with an older Super Stroke Mid Slim 2.0 grip in blue and white. The Mid Slim was designed to fit in between the Ultra Slim 1.0 and the Slim 3.0 that was a popular grip on tour.

Then why has every shaft I had pured always magically been logo down when built.
