Making the change to graphite iron shafts can be difficult for many golfers. Senior players that are used to playing steel shafted irons and wedges can be discouraged by having to completely change the feel of their entire bag. Aerotech has solved this issue with the introduction of the SteelFiber shaft. These shafts are designed with an ultra-strength steel outer layer and a lightweight graphite core.

The result is a golf shaft that feels similar to steel and gives players the playing advantages of high modulus graphite. The SteelFiber golf shaft is the ideal choice for players transitioning out of steel iron and wedge shafts into lighter, easier-to-swing options. Players that struggle with arm or wrist injuries can also benefit from the vibration dampening effect of these steel-graphite hybrid shafts.

Key Features

The Steel Fiber Surface Layer and Graphite Inner Core combine to produce a better feeling, higher performing iron and wedge shaft .

The multi-layer construction delivers more performance, more forgiveness, and more consistency.

The constant weight design ensures that players get a full iron and wedge set that is more balanced.

Design and Technology

Aerotech set out to design a golf shaft that allows golfers of any age and swing ability to play a premium, high-performance golf shaft. By combining steel and graphite into a multi-layer design, Aerotech is able to give players the familiar feel of steel shafts with more accurate and optimized weight and performance characteristics in their SteelFiber model. 

The constant weight feature is unique to this design as the graphite component allows engineers to build each shaft to the exact weight of each player preference. The Aerotech SteelFiber delivers golfers the best of both worlds in feel and ball flight performance with their multi-material hybrid configuration.

I play a graphite shaft in my driving iron so I assumed the SteelFiber shaft would resemble that in feel. I was surprised however at how much the SteelFiber reminded me of traditional steel shafts. Aerotech does an amazing job at delivering a shaft that is lightweight yet incredibly stable. The SteelFiber shaft was easy to launch, incredibly consistent, and I noticed a dramatic reduction in vibration at and after impact with the golf ball.

Aerotech packs the maximum amount of technology into the SteelFiber shaft. The result is a shaft that is more stable and more forgiving. The SteelFiber uses a blend of materials to meticulously control weight and thickness. I would not hesitate to recommend the SteelFiber shaft to players of any ability and swing type as they look for better feel and reduced impact stress. Players will likely be able to play more golf longer by switching into the SteelFiber from Aerotech.


  • High performance graphite with the familiar feel of steel make SteelFiber a great all-around shaft.
  • The multi-layer construction delivers more performance, more forgiveness, and more consistency.
  • The constant weight design ensures that players get a full iron and wedge set that is more balanced.


  • Players cannot choice different flexes within the weight categories of the SteelFiber shaft offerings.
  • Players seeking a more rigid feeling shaft will likely need to stick to all-steel constructions in their set.
  • Aerotech SteelFiber shafts carry an additional upcharge and can make expensive iron sets more costly.

Our Experience

The Aerotech Steelfiber i95 is a high-performing graphite iron shaft that offers a smooth and responsive feel. It features a graphite core wrapped in 59 miles of ultra-thin steel fibers, providing the benefits of both graphite and steel.

Our testing found the Steelfiber i95 to have a very smooth transition and load/release feel, even on mishits. The shaft provides good feedback without harsh vibrations. It's well-suited for players with moderate swing speeds, offering distance gains in the long and mid irons while maintaining accuracy and spin control. 

The lightweight 95-gram design makes the Steelfiber i95 easy to swing, helping generate more clubhead speed for some players. However, we did notice slightly increased dispersion in the short irons compared to heavier steel shafts. 

Overall, the Aerotech Steelfiber i95 is a tour-proven graphite shaft that provides an excellent blend of feel, performance, and forgiveness. It's a great option for players looking to transition to a lighter-weight shaft without sacrificing control.
