While the SteelFiber technology was originally designed for iron shafts, Aerotech incorporated the design into a line of highly successful wood shafts as well. The SteelFiber wood shafts are available in three weights: 65, 75 and 85 gram. SteelFiber wood shafts are limited to 65 grams and up due to the full layer of steel on the shafts surface. Therefore, this technology is a perfect fit for fairway woods or by players who can benefit from a moderate weighted driver shaft. If a player is looking for all the control of a steel shaft in their driver and fairway woods but wants to benefit from the lighter weights and vibration dampening properties of graphite then the SteelFiber wood shaft is the right choice.
