The SteelFiber i95 is $60 a shaft, and it’s still one of the first graphite iron shafts I’d put in front of a golfer who’s tired of heavy steel. But it’s not a distance shaft, and there’s more than one SteelFiber with almost the same name.
Is the Aerotech SteelFiber i95 Shaft worth buying?
When I got fitted for the PXG Gen 8 irons, the fitter put the XP head on a SteelFiber 110, the heavier version of this shaft. His words were “steel wrapped in graphite.” He told me it was five grams heavier than the MMT I’d just hit and should feel a little stiffer. I didn’t end up in it. We went with a 105 graphite MMT, because that’s where I made the best contact of the whole day.
That’s how you should think about the i95 too. It’s a good shaft. But nobody can tell you from a spec sheet whether it’s your shaft. You find out by hitting it.
So here’s what it is, what it costs, which version to buy, and who I’d actually hand it to.
Quick Overview
- It’s a 95 gram iron shaft with a graphite core and a stainless steel fiber outer layer.
- It’s constant weight, so every shaft in the set weighs the same no matter the length.
- The version you want is the .355 taper tip CW, in Regular, Stiff or X-Stiff.
- It’s $60 a shaft at True Temper, GolfWorks and Golf Galaxy, so a seven-iron set is $420 before grips and labor.
- It isn’t discontinued. Aerotech is part of True Temper now, and the shaft is still sold as Steelfiber CW.

The i95 Makes the Most Sense When You’re Coming Down From Heavy Steel
Here’s who this shaft is really for. You’ve been playing steel somewhere around 105 to 125 grams. Your irons feel heavy. Maybe your hands are feeling it by the back nine. And you don’t want to jump all the way to a really light graphite shaft.
That’s the gap the i95 fills. At 95 grams, it’s a real step down in weight, but it’s not so light that it feels like a different sport.
And it’s constant weight. Some shaft sets change weight from your long irons to your wedges. With the i95, every shaft is 95 grams, no matter how long or short the club is. That keeps a matched set simple to build.
Now, here’s the thing about dropping weight. It changes your timing. Some golfers get faster and make better contact. Some get quick and start spraying it. That’s exactly why my fitter kept swapping shafts in the same head until my strikes got consistent.
So if you’re going to try it, hit it against your current shaft in the same head. Watch where you’re making contact and how far offline the misses go. If the strikes get better, that’s your answer. And if you’re still deciding between the two materials, here’s my full breakdown of graphite vs steel golf shafts.
The Steel Fiber Layer Is Why It Doesn’t Feel Like Cheap Graphite
The knock on lightweight graphite in irons has always been that it can feel loose. Kind of hollow. You lose the feedback you got from steel.
Aerotech’s answer was to wrap the graphite core in stainless steel fiber. True Temper says there are more than 59 miles of steel fiber in the construction. The idea is that the graphite core takes out the sting and the steel mesh gives you back the stability and the feel of a steel shaft.
You can see it in the photo. The finish looks brushed, almost like metal, not like painted graphite.
The torque is low for a graphite iron shaft, too. It’s 2.1 degrees in Regular, 2.0 in Stiff and 1.8 in X-Stiff. Lower torque means the head twists less through impact, and that’s a big part of why it’s built to feel closer to steel.
Will you feel less vibration? Probably, if steel has been beating up your hands. But that’s personal, so I wouldn’t buy a full set on that alone.
Buy the .355 Taper Tip CW, Not the Parallel or the FC
This is where people buy the wrong shaft.
There are a few SteelFibers that show up in the same searches. The one this review covers is the CW taper tip. CW stands for constant weight, it has a .355 inch tip, and you don’t trim the tip. You cut it to length from the butt end. If you’re building them yourself, here’s how to go about cutting a graphite shaft without destroying it.
Then there’s the .370 parallel tip i95. True Temper lists it separately at $55. It’s not a cheaper version of the same thing. The tip and the build are different, so it’s a different route for your club builder.
The FC CW is also a separate shaft, built for a different launch and flight. And Private Reserve is its own product too. If you see a great review of one of those, it’s not a review of this shaft.
One more thing that confuses people. Aerotech became part of True Temper in 2019. So on True Temper’s site, this shaft is listed as Steelfiber CW (Taper), and the 95 gram option is still there. In 2023, the graphics were updated to put “cw” right on the shaft, and the performance didn’t change. If you see an older i95 without the “cw” on it, don’t panic. It’s the same shaft.
At $60 a Shaft, It Costs Less Than the Graphite Shafts I’d Test Next to It
The i95 is $60 a shaft at True Temper, GolfWorks and Golf Galaxy.
For a seven-iron set, that’s $420 in shafts. Nine shafts is $540. And that’s before grips, ferrules, installation and any fitting, so don’t think of $420 as the price of a new set of irons.
Now compare that to what I’d put next to it in a fitting. The KBS TGI 95 is also a 95 gram .355 taper shaft, and GolfWorks had it at $71.95. That’s about $12 more per shaft. The Fujikura Axiom 105 is newer, 10 grams heavier, and Fairway Golf USA had it at $115. That’s almost double.
The Mitsubishi MMT 95 taper belongs in the same fitting too. Remember, an MMT is what I ended up in during my Gen 8 fitting. I couldn’t find a current US price on the 95, though.
So the i95 is the value pick in that group. That doesn’t make it the best shaft for you. But if it fits you as well as the others, you’re saving real money across a full set.
What I Don’t Love
There’s a catch. And it’s not the shaft, it’s the ordering.
True Temper’s site doesn’t even call it the i95 anymore. You’re looking for Steelfiber CW (Taper) in 95 grams, and the .370 parallel i95 sits right next to it for $55. Grab the cheaper one by mistake and you’ve got a shaft with a different tip that your builder has to handle a different way. Before you click buy, check for CW, taper and .355 on the listing. If any of those are missing, it’s not the shaft I’m talking about.
And don’t buy it for distance. A lighter shaft only gets you more yards if your timing holds up, and that’s on your swing, not the shaft.
True Temper also doesn’t publish a warranty term or a swing speed range on the product page. That bugs me a little on a shaft you’re going to put in a whole set. So you can’t pick a flex off a chart and call it done. Here’s how I’d determine your golf shaft flex instead.
Who It’s For
Buy it if:
- You play 105 to 125 gram steel and your irons feel too heavy.
- You want graphite in your irons but still want them to feel stable and solid.
- You want a constant weight set that’s easy to build and match.
- You’re getting refit anyway and want a lighter shaft on the list.
Skip it if:
- You’re buying it for a guaranteed 10 or 20 more yards.
- You want the feel of a heavy steel shaft, just in graphite.
- You’re picking a flex off a label or a swing speed chart without hitting it.
Frequently Asked Questions
Are Aerotech SteelFiber i95 shafts any good?
Yes, when the weight and flex fit you. The i95 gives you a 95 gram graphite shaft with a steel fiber outer layer and low torque, so it’s built to feel stable and smooth. What it won’t do is promise you more distance or better accuracy. That depends on how you swing it in your own head.
Do SteelFiber shafts play stiff?
You can’t tell from the label. The torque is low, 2.0 degrees in the Stiff, which helps the shaft feel firm and stable. But how stiff it plays for you depends on your swing, the head, the length and the build. If you’re coming down from heavy steel, hit the exact flex before you buy a set.
What’s the difference between the SteelFiber i95 and i110?
The i110 is the heavier shaft, by 15 grams. Some golfers get a tighter dispersion with the heavier i110, and some golfers make better contact with the lighter i95. Neither one is better for everybody. Hit both in the same head and pick the one where you strike it best.
Is the SteelFiber i95 a good shaft for seniors?
It can be, but age isn’t what decides it. The i95 helps golfers who do better with a lighter shaft or who want less sting in their hands. Plenty of seniors fit that. Plenty don’t. Pick it because your contact and comfort get better, not because of a birthday.
What swing speed is the SteelFiber i95 for?
True Temper doesn’t publish a swing speed range for it, and swing speed alone isn’t enough to pick a shaft anyway. Launch, spin, where you hit it on the face, your tempo and your build all matter. The 95 gram weight makes it a good candidate if you’re coming down from heavier steel.
Final Thoughts: Aerotech SteelFiber i95 Shaft Review
Here’s where I land. If your steel irons feel heavy and you want something lighter without going flimsy, the i95 is one of the first shafts I’d try, and at $60 a shaft it won’t wreck the budget for a full set. Just make sure the listing says .355 taper CW. But if you’re shopping for distance, or you love the weight of heavy steel, keep your money and stay where you are.
