Frequently Asked Questions

 

Q: What SteelFiber weight is best for me? 

A:  This is the most common question customers ask when switching to Steelfiber shafts for the first time.  When selecting a shaft being mindful of weight change from your current shaft is the most crucial. The weight change in the transition is probably the most important aspect as too drastic of a reduction can result in the player having a difficult time relating to the club in motion.  Going up or down 20g in weight or less is usually a good starting point.  

Another consideration is making sure that the swing weight is as close as possible to that of your current set or what you have played in the past. If you go to a lighter shaft you will also have the swing weight lighter (lighter shaft means lighter swing weight unless compensated for in the build) the result can be a very different overall club feel/balance to better players. 

Q: Are SteelFiber shafts stiffer than normal graphite shafts?:

A:  Yes.  Generally speaking, the i95 and i110 are thought to perform firm to flex when compared to steel shafts of lighter weight (KBS Tour 90, PX 95 flighted, DG SL, Nippon 850/950). The SteelFiber does tend to perform with the characteristics associated with a firmer flex (lower spin/launch) due to the tip stiffness and overall frequency profile. For the most part low handicappers and tour players transitioning from full weight steel in the 120-130 gram range will usually stay in the same flex and those transitioning from lighter weight steel or composite will generally go one flex softer.

Q: I would like a SteelFiber in a 2 iron, is this possible?

A:  Although Aerotech does not make a dedicated 2 iron taper tip shaft in any weight, we can find you a 3 iron shaft that can work as a 2 iron. The taper tip 3 iron shaft is long enough to be played 2 inches longer than a standard length 2-iron, so length is not a concern.  We have over a hundred individual 3 irons and we can select one with a frequency on the very high end of the CPM tolerance for the 3 iron and one on the low end of the CPM tolerance for the 2 iron. This hand selection would ensure a proper stiffness progression from the 3i to the 2i.  If you would like a 2 iron shaft please purchase a 3 iron in the shaft you want.  During checkout please let us know you would like a 2 iron shaft instead of a 3 iron under the Order Instructions/Comments section.

Q: What is the difference in .370 tip and .355 tip?

A:  The SteelFiber shaft is offered in two versions for each weight. The cw (constant weight) version is designed for a taper tip (.355 diameter) hosel.  The cw taper tips sets are produced as a set and each shaft is labeled for a particular head. The raw shaft lengths range from 36.5 inches in the PW to 40 inches in the 3 iron. After installation, they are cut to length from the butt end only.  The cw version when installed is exactly that, constant weight through the set. For example, when the i95 set is butt trimmed to standard length, all of the shafts will weigh the same, approx. 90 grams. Iron heads designed for taper tip shafts lean towards the less forgiving designs and tour models. Although there are exceptions. For example, Ping and Titleist use only the .355 taper tip hosel.

 The version without the cw is designed for a parallel tip (.370 diameter) hosel. The parallel tip shafts, whether steel or our shaft, are produced at a single length. The SteelFiber is 41 inches as a raw shaft. Unlike the taper tip (with rare exceptions), the parallel tip shaft is tip trimmed to specifications (a specific amount for each iron) prior to installation and then butt trimmed to playing length. This process results in a descending weight set with the 3 iron shaft weighing the most and the pw the least. The weight progression is consistent. Companies like Taylormade and Callaway manufacture iron heads with both taper and parallel tip.

Q: Is there an advantage to one tip size over the other?

A:  From an installation standpoint, the advantage lies in having the proper tip diameter for a particular iron head. From a production standpoint, the SteelFiber in both versions have very similar flexural profiles, torque values, and frequency progression.  As for performance, there is no reason for one version to produce different results in terms of consistency, trajectory, or workability. It is a preference as much as anything detectable through performance.

Q: Do SteelFibers need to be pured/spine aligned? 

A:  Greatgolshafts.com would never discourage a player from having shafts pured/spined, at the very least it will never have a negative effect on performance and can have a positive psychological effect on some players. A majority of PGA and Champions Tour players using Aerotech SteelFiber shafts have them installed without this process. The SteelFiber is extremely uniform and consistent which is a result of the design profile achieved through filament winding (vs sheet wrapping with overlap) which is a seamless construction. Due to the perimeter weighted nature of the shaft (greater density/weight in the outer wall due to the steel fiber) the MOI has been increased to further stabilize the tip at impact.  

Q: can you explain kick points to me?

A:  When you swing your club, the shaft bends or "loads" to store power. It then straightens or "unloads" to release that power and help create clubhead speed. The flex point, also called the kick point, is the spot on the shaft where most of that bending takes place. The kick point is important because it helps determine the ball's trajectory after you hit it. Your shaft can have a high, medium or low kick point.  The higher the kick point is on the shaft, the lower the ball flight will be.  A low kick point gives you a higher ball flight and a medium kick point gives you a medium ball flight, and a high kick point will give you the lowest ball flight.
