While the brand has been established since 2023, Aretera Golf has seen a surge in popularity and discussion within the past year, specifically after the launch of their EC1 shafts. Although the Alpha One came before them, it was the EC1 which made its way into the golf world with success and accolades, especially impressing the group of THP Community members whose hands we put both driver and fairway shafts into for a thorough testing.
However, Aretera isn’t here to try and be a one trick pony, as we recently discussed in a feature article about the brand, they truly are built different. That is why they are announcing their next premium shaft design creation, the AO2.

Aretera AO2 Shafts
The AO2 shafts are a culmination of intense research and testing by Aretera to take some of their initial concepts and ideas into account while blending them with even more modern technological advancements. At their core, the AO2 line of shafts are a design which have a firmer tip and middle but maintain a more active butt section.
As Aretera describes it, this makes for a more enhanced connection for what they refer to as “hand feel” golfers who want torsional stability and maximum power transfer efficiency without sacrificing the feel under the hands. As you might guess, this combination of design traits makes for a very unique EI Profile, which can be seen below:

The ability to create such an interesting profile comes back to the technology which Aretera hangs their hats on, namely PowerGrid and Coreless Design. For the former, that comes down to the company’s relentless pursuit of the most premium materials available. Ultra-high modulus exotic fibers woven into spread tow fabric which is thinner, lighter, and possesses more multi-directional benefits compared to more of the standard materials.


That PowerGrid application is then taken to another level when combined with the Coreless Design aspect. With the way most shafts are made, the layering process creates a natural bias both in how the materials are applied as well as the natural tendency of one trait to overwhelm the other when it comes to flex versus feel. For Aretera, the PowerGrid materials along with the alternating staking process means they use 16-20 plies compared to the traditional 5-7.

Those added layers mean more fine tuning in terms of being able to create torsional stability, feel, and flex in unison as opposed to the usual give and take battle that occurs. Not only has Aretera been able to place material where the most stresses and deformations occur, but it is key to creating the “Aretera Feel” which THP’ers in particular have long raved about.
The Details
Aretera is unveiling the new AO2 shafts not as a replacement to the EC1, but a sibling within the lineup. As has become standard for them, there will be both Gray and Blue models with the main difference being a 7% stiffer tip section in the Gray. This aspect combined with the multitude of weight and flex options opens up a very unique fitting matrix compared to others.
This is officially Aretera AO2 shafts launch week and it drops with a price of $419.99. The line will be available at their ever growing network of certified fitters across the nation. For more information visit their website at areteragolf.com.

Doing a side by side with these would be really interesting for me. In my mind, I don’t think it would work, but would love to be proven wrong.
[/QUOTE]
That what wouldn’t work?
Before I get to a computer to sit down with deeper thoughts, amidst the chaos, I did get swings in with these, as well as the Alpha One and EC1 models in order to get some overarching feedback of similarities and differences in feel.
They all three have what I would absolutely describe as an “Aretera Feel” to them. What I mean is there’s much more similarities between the models that are also unique to the brand compared to feedback from other driver shafts that I have had in play, and do play.
They clearly have their methodology in terms of application techniques and the overall science involved, they believe it makes them unique, and in my experience, it does.

It’s definitely, imo, unique. There’s a flow to it all, but not at the cost of stability. That in and of itself isn’t something only Aretera achieves imo, but the methods and tech design they use to do it, is.

The stiffer tip and the softer butt – in my mind the opposite would work better for me. That said, I think a side by side with the EC1 would be a good case study for me.

What makes you think that though? You need more launch? What’s the parameter for that guess, is what I’m curious of
[QUOTE=”Jman, post: 13608538, member: 1579″]
The EC1 is softer in the middle (they call it “more compliant”)with more stiffness in the top section as well as the butt end of the shaft. So it’s a pretty different profile.

Is that similar to the profile of the UST THP Proto shafts from last year?

I am in pursuit of launch – yes. Also, the thought of the softer butt end just gives me pause, both from a feel perspective, as well as left / right dispersion.
I am due for a good fitting though to help sort it out.

A softer handle section doesn’t automatically mean wider dispersion though, it’s the thing about shaft profiles, it’s a three part dance rather than a one part more than the other.
I can say so far, I have no doubt they’re meant to hold up to aggressive moves still, and I definitely get a stronger flight than I do with the EC1.

This is one of those cases where I’d love to learn I am completely wrong. I can take being wrong well if it improves my driver game.
Can’t wait to see more of your EC1 comparisons.

That’s great to hear. I was fit for the EC1 Blue 75/5 in my Callaway Elyte this year and I could point and shoot that thing with ease. My only issue and why I stopped playing it was the launch and apex were very high. Never got to try the grey to see if It was essentially the same but lower launching so if these are similar but with stronger ball flight I’ll have to grab one fast

Keep in mind, clubhead and ball will always play the biggest role in impacting/lowering (in this case) ball flight compared to the shaft.

Yup, shafts don’t inherently launch or spin for people.
But they [U]may[/U] affect the timing which may affect dynamic launch/flight characteristics.
Weight of shaft is likely just as important, large contributor to feel / timing.

They are timing mechanisms, yes.
My point remains true though, and it’s something we always point out as in the internet, most believe a change in shaft alone will drastically alters the launch and spin data. It can and does impact, but not to the degree many believe.
The ei profile of the Alpha 2 seems similar to the Grafalloy Prolaunch Blue. All all time classic shaft.
Throw in the new Aretera tech into that. You might make another all timer

I was playing the Elyte in 9.5 at that time and that was the lowest loft I could play for my driver swing to get enough spin on the ball to avoid it becoming unstable. I’m currently gaming the GT2 In 10 degrees with Hzrdous Yellow 75g X stiff and I might be wrong but to my eye it looks like it’s coming out lower than my Elyte was. But what is the primary factor for height and apex? Cause I’m currently debating upgrading my iron shafts from stiff to x stiff for the same reason.

Clubhead, and the internal clubhead design, will always have the biggest impact. Golf ball is often overlooked as well.
Can’t just assume that X will make everything lower. It might, but it also may not move things much at all, or have secondary impacts where dispersion and directional miss tendency is concerned.
I’d encourage a good, and I emphasize good, fitter.

Softer Butt, stiffer mid, into a pretty stiff stable tip.
I think the aretera shaft may be more abrupt in where it transitions, which is the most interesting part. But this aligns with their philosophy, take what people like / want to feel (either in the butt or in the mid) and improve energy transfer without compromising stability.
The sim is back up and running so my plan is to start data collection today. Really eager to get some hard data to go with what I’m seeing as I work towards the full review
These have me….in my thoughts.
They remind me SOOOOOOOOO much of the Alpha One’s, a scary amount in fact.
With this being my third experience reviewing Aretera’s designs, I’m absolutely going to coin the phrase “Aretera Feel” when talking about these, and the other options.
Yes, there’s more THERE to them than the EC1, but the overall flow through the swing without sacrificing what I consider stability through the zone is very familiar, and very unique.
The science there in their applications and techniques has to be doing something, because alternating through several similarly profiled (launch and spin, as well as weight and flex) shafts across manufacturers there were flight likenesses, but nothing felt like these do.
I’m not going to spit out data yet as I’m collecting that for the review, but my speeds are good, quite good actually.
I can definitely tell the difference in the blue and gray through the swing under the hands, even then, it’s not as dramatic as I thought it might be.
I’ve hit them so far in the TD and core Elyte heads, and the spin on both are low 2’s, about 200 rpm between one another, which is right on what I’d expect to see.
Also, they do look positively badass installed.

This is awesome info to hear. Love the “Aretera Feel”, so happy to see it continuing in their new shafts
Can someone explain to me on these shafts the picture of the two rows of bars I understand that one is for the butt one is for the mid and one is for the stiff but why are there two rows of them on the shaft?
Also [USER=1579]@Jman[/USER] I am very curious to hear the differences numerically between the ec1 and this new model. I. E. Launch spin and ball speed differences in the same head.
I value your opinions and insights and you have had a positive influence on some of my purchasing decisions especially in the fairway wood category.

To my knowledge, it’s the two models in the given shaft design, meaning gray and blue. This release did a better job of color coding each, the bars with slashes are the opposite color model. You’ll notice, the profile is the same except in the tip, which the grey has more bar filled to illustrate the 7% stiffer tip section.
Drastically different than EC1. These are, imo, more in the vein of the Ventus Killer that the original Alpha One was intended to be. They spin less, and they have stronger launch/flight when I hit both grays in the same head.
I’ve actually been a bit surprised by how much lower spin they are for me, personally.
[QUOTE=”noodle3872, post: 13654090, member: 56″]Aretera calls the “profile indicators”. The box with the angled lines denotes the “torsional stability“ or torque of that section of the shaft and the other box filled with the shaft profile color (blue or grey) denotes the “bending stiffness“ or flex of that section of the shaft.
[URL unfurl=”true”]https://www.areteragolf.com/shafts-ao2[/URL][/QUOTE]Ok cool so one is torque and other stiffness per section.
Thanks
