Hireko has added yet another shaft series to our extensive line up for your repair and retrofitting needs. This shaft comes from Apollo called the Constant Weight Steel or CWS for short. Unlike most shafts we stock, these shafts are not designed to fit any of Hireko irons or wedges because they are taper tipped. These are designed exclusively to retrofit existing pro-line irons and wedges requiring a 0.355” taper tip shaft.
Who is the CWS shafts for?
The Apollo CWS are primarily designed for the more advanced player who desires more of a flatter or tour type trajectory. The firm tip section or high bend point is typically favored by better players who tend to hold their release until later in the swing. This enhances distance control and a tighter shot pattern, in particular the scoring clubs where it is needed most. Lastly, the CWS series places an emphasis on shaft consistency as they are manufactured to exacting weights and balance point positions to ensure consistent flex matching throughout the set.
What is Constant Weight?
There are three ways that shafts can be produced. One of which is Constant Weight. This a shafting concept in which all of the shafts in a given set of irons will weigh the same regardless of their length.
This does not occur with unitized, parallel tip shafts or even certain taper tip shafts that start out as a master shaft, tip trimmed to increase the stiffness and then swaged to form the tapered tip section. As more material is tip trimmed, the shaft becomes progressively lighter and lighter the shorter the shaft. This is described as a Descending Weight shaft. For the record, Ascending Weight is the complete opposite (becoming heavier the shorter the shaft in the set is) and appears in only a few shafts ever marketed.
Take a look at the chart for a second, this will show the differences in raw and cut weights when you compare a constant weight set with a descending weight set. By the time you get to the scoring clubs, you are looking at a 10g difference.
What are the benefits of constant weight designs?
Think about this for a second. If the a shaft’s weight is greater with the exact same step pattern and length then this means there is an increase in wall thicknesses. Because of this, there are several byproducts such as an increase in the overall weight of the club, steeper frequency slope, stiffer tip section and lower torque. This is especially true the shorter the shaft becomes as the weight discrepancy increases. This is why touring professional prefer the constant weight version of a shaft pattern more so than the descending mass model when available simply because of the greater control they get.
Here is the DSFI data that we produce for our annual Shaft Fitting Addendum so you can compare them to other shafts we have tested.
With taper tip shafts, there is no tip trimming required. However, this requires the clubmaker to purchase or stock a specific raw length for each head. Here are those recommended raw lengths:
The Apollo CWS is the most economical standard weight, high bend point taper tip shaft on the market. This not only gives clubmakers another option for retrofitting full sets or iron or wedges, but also for repairs. If you or your customer is looking for a lower trajectory taper tip shaft with tight tolerances, then the Apollo Constant Weight Steel will make an excellent choice.
