Aerotech Steelfiber i110 Review – Specs, Flex, Weight


In this review, we cover Steelfiber i110 graphite iron shafts from Aerotech.

Let’s learn more about these shafts that have quickly become quite popular with golfers around the globe.

Aerotech Steelfiber i110 Overview

A critical component in improving your game is choosing the correct shaft, but what does Aerotech’s SteelFibre i110, constructed from both steel and graphite fibres, offer?

Well, to provide a quick overview of these shafts, while they are similar to steel shafts in terms of the ball flight they provide, their overall feel is smooth and consistent, much like if you were playing with a full graphite shaft.

Interestingly, in terms of construction, the core of the shaft is wrapped with 59 miles of steel fibre!

Why Is Aerotech’s Steelfiber i110 So Popular?


Perhaps the main reason why these shafts have become so popular is due to their steel and graphite fibre construction.

Here, you get the best of both worlds. For example, the graphic fibres provide vibration dampening and give the club a lightweight, easy-to-swing feel, while the steel in the shaft brings overall consistency and, most notably, stability.

They also promote a far more consistent swing, thanks to the stepless design of the shaft, which means it has a consistent diameter, making clubs with the shafts more accurate.

How Does Aerotech Steelfiber i110 Perform?


The main aim behind these clubs is to help golfers achieve a swing that’s consistent, time and time again.

Thanks to the construction, while out on the course, we immediately noticed that clubs with the Aerotech Steelfiber i110 shafts felt extremely smooth to use.

Any vibrations were noticeably lower too, and shot accuracy improved significantly for mid-to-high handicappers.

That’s not to say that these shafts are only for casual golfers; even the scratch golfers in the test group loved the way that they felt.

Another noticeable feature is that despite their use of graphite, they still provide the same control and ball flight characteristics as steel iron shafts.

Steelfiber Shaft Specs

  • Tip: .370″
  • Weight: 110g
  • Length: 41″

What Flexes Are Available? What Swing Speeds Do They Suit?

Two flex options are available: X-flex and Y-flex.

As far as swing speeds go, thanks to the available flex options, there’s no swing speed that these shafts are particularly suited for.

That being said, the X-flex is best for swing speeds between 93-107 mph, and the Y-flex for anything above that.

Further customization is possible for each individual to get the weight and feel they prefer, as the shaft can be trimmed where necessary.

Without a doubt, to get the most out of using these shafts, golfers should be prepared to have their swing thoroughly tested and then have shafts properly fitted to match that.

Things that should be checked include swing speed and tempo as well as ball flight characteristics.

From the collected data, shaft fitting experts can work out the perfect shaft weight, flex, as well as the overall length thereof, which can significantly improve your game.

What Weights Are Available? 

The standard weight available for the Steelfiber i110 is 110g, but as mentioned above, through professional shaft fitting and based on your swing speed, tempo, and ball flight characteristics, shaft weights can be adjusted.

Why Is It So Good?

There are several reasons why golfers love Steelfiber i110 shafts.

To start, it’s because they play much the same way as heavier steel shafts when it comes to the flight of your ball.

They are also incredibly accurate, leading to more consistency in your swing, and what’s not to love about the vibration dampening offered by the graphite fibres that form part of the shaft’s construction?

On the whole, you’ll be hitting the ball just as far as you do with heavier steel shafts, with a tight dispersion too.

Aerotech Steelfiber i110 First Impressions


Many of the golfers we gave the Steelfiber i110s to try out fell in love with the shafts pretty quickly.

On the whole, once they’ve been custom-fitted, they are pretty easy to get used to.

There’s a cautionary note here, however.

If you are a regular user of steel shafts, should you make the change to i110s, always keep them within 20g for the best possible chance of making the most of their performance upgrade.

In other words, if you used anything heavier than a 130g steel shaft, you might not like them as much.

That said, in terms of first impressions, I loved these immediately.

I mean, who doesn’t want the accuracy that a steel shaft provides with the extra advantages that a graphite shaft brings to the party?

It’s no wonder so many Tour pros are turning to these Steelfiber shafts for their clubs.

It’s interesting to note, however,  that when using these shafts, you do lose a bit of spin.

Key Features & Performance

Perhaps the biggest feature of these shafts is their construction.

We’ve already sung the praises of what the combination of graphite fibres and steel brings to the party, but there’s also the stepless design as well.

Once you’ve set the shafts up correctly, you’ll notice that they have excellent mid-high launch characteristics, but as we’ve already mentioned, don’t expect anything more than mid-spin.

Performance out on the course is marked by consistent distance control, something that can really help you improve your game and add more consistency to your shotmaking.

Aerotech Steelfiber i110 Irons Review

There’s no doubt that these shafts will improve your iron game, mainly because they will make you far more consistent.

Again, however, they won’t add as much spin control as you might have with other shafts.

These shafts will benefit your shorter game close to the green as well, again thanks to their consistency in shotmaking when it comes to distance control.

Yes, they will provide spin control too, but again, there are other shafts that can help more in that regard.

It’s just a case of getting used to how they perform, but most golfers will adapt quickly.
