Weighing around 3 pounds for the set, these graphite shafts offer a balance between lightweight performance and stability, helping reduce arm fatigue compared to heavier steel options. Aerotech’s SteelFiber line is known for combining graphite's smooth feel with steel-like consistency, often delivering a mid to low kick point that supports a more penetrating ball flight.

The shafts fit standard iron lengths (.355 tip size) and come in a 7-shaft set covering 4 through pitching wedge, making them compatible with most iron sets. Customer feedback is positive, with a 4.6-star rating, suggesting users appreciate their performance and feel. The relatively high price might make it harder for beginners to understand if these are perfect for their game.

These shafts represent a strong option for players wanting to upgrade from steel to graphite without losing too much control, but beginners or players who prefer very flexible shafts might want to explore other choices.

The AeroTech SteelFiber i80cw graphite iron shafts are a solid choice for golfers who want a combination of lightweight feel and steady control. These shafts have a Regular flex, which suits players with moderate swing speeds who need a balance between flexibility and stability. Weighing around 85 grams, they are lighter than typical steel shafts, helping reduce arm fatigue and improve swing speed, which can benefit mid to high-handicap players. The graphite material also helps absorb vibrations for added comfort during impact.

The SteelFiber series is known for blending steel-like control with graphite’s lighter weight, making these shafts feel responsive without being too whippy. The .355 taper tip means they fit most standard iron heads, and the length is designed for typical iron setups from 4-iron to pitching wedge. The standard synthetic rubber grips are comfortable but not specialized, so players who prefer custom grips might want to upgrade.

These shafts may not offer enough stiffness for very fast swingers or low-handicap players who favor more feedback and control. The AeroTech SteelFiber i80cw shafts are ideal for those seeking regular flex graphite shafts that deliver a smooth feel and easier swing speed, especially for mid-level golfers looking to reduce fatigue without losing too much control.
