The 2011 Shaft Fitting Addendum is Now Available

If you are looking to advance your knowledge on the ever-confusing world of shafts, take this opportunity to download the 2011 Shaft Fitting Addendum.  This is a companion piece to one of the best books written about shafts called the Modern Guide to Shaft Fitting. And the best part is both of these books are available for free.


For 19 consecutive years, the annual Shaft Fitting Addendum has been the number one resource available for clubmakers and ordinary golfers to find invaluable information on golf shafts. This is just another example of how Hireko is helping out clubmakers, club fitters and fellow golfers alike by providing you with such indispensable information so you can make more well-informed choices when it comes to purchasing new equipment.

What Type of Information Will You Find?

For those that are not already familiar with the Shaft Fitting Addendum, the first thing you will find out is not all R-flex shafts are created equal – that is in terms of flex, torque, bend point, etc. as every manufacturer are their own standard.  In reality, there are no industry standards for shafts and the reason why this book serves as a valuable guide.  I have spent the last 22 years conducting all the 50,000+ measurements on over 3000 shafts that are listed in this text; all of which have been tested using testing methods and equipment.  What this ensures is consistency in testing and reliable results.

There are 19 published specifications listed for each shaft that include:

Flex, Uncut Shaft Weight, Tip Diameter, Butt Diameter, Uncut Shaft Balance Point, Cut Shaft Balance Point, Completed Club Balance Point, Total Assembled Club Weight, Head Weight, Grip Weight, Cut Shaft Weight, Completed Club Frequency, Butt Deflection, Tip Deflection, T/B Ratio, Cut Shaft Torque, Raw Shaft Torque, Club Length (and wood bore type) and DSFI (Dynamic Shaft Fitting Index) Rating

To give you a peek of what information is available, look at the chart below. You can compare shafts from the same or even different manufacturers that are of approximately the same overall stiffness and weight.  In this case the Aldila Serrano, Fujikura Fit-On E250, Grafalloy ProLaunch Blue 55, ProLaunch Platinum with Axis Technology, New Image Red Image Graphite and our own True Ace Death Stick are all mid-50g shafts of similar frequencies and stiffness index.  But find out what the differences are.

How Do I Use the Information?

While offering all of this data is great, being able to take this information, understand what all the numbers represent and then be able apply it into your everyday fitting is another.  This is why we established the Dynamic Shaft Fitting Index (or DSFI for short).  The DSFI takes the Completed Club Frequency, Butt Deflection, Tip Deflection, Cut Shaft Torque and Club Length and puts it into a complex algorithm to put a number on stiffness.  No longer do you need to rely solely on the generic flex designations by the manufacturers.

In Chapter 5, the addendum explains why you may want to select the Aldila Serrano over the Grafalloy ProLaunch Platinum or visa versa. You can also relate Dynamic Shaft Fitting Index to the clubhead speed or the golfer’s driver or 5-iron and be able to make appropriate shaft selections. However, swing speed is only a starting point – certain golfers will use different flexes based on their tempo and length of their swing rather just swing speed.  The 2011 Shaft Fitting Addendum can help you understand these issues.

The 190 page Shaft Fitting Addendum is broken down into 5 chapters, but you don’t have to download everything.  The first shaft provides the legends of what each of the specifications are and we would encourage you to read that carefully.  Chapters 2 and 5 are the nuts and bolts of the 2011 Shaft Fitting Addendum with Chapter 2 showing the data and Chapter 5 providing the how to use the information with the master charts in order of stiffness.

In addition, club fitters or even ordinary golfers can look for suitable replacement shafts that may not exist anymore by looking through the archived shafts (Chapters 3 and 4). These are all the shafts tested that are no longer available but contain information on shafts you may have hit in the past. Matching shafts of similar cut weight, frequency, cut torque and tip and butt deflections will help you find that one shaft you owned previously that they liked so dearly.

Again, if you are an interested at all in shafts or shaft fitting, then this single source of information is indispensable to satisfy the knowledge you might have.

How Do You Spell Relief? Meet the Power Play Adrenaline Uni-Rail Sole

Just arrived and now in stock are two new models in the Power Play Adrenaline line to add instant relief to a golf bag near you. How you ask? Both the Power Play Adrenaline fairway woods and hybrids have a distinctive Uni-Rail sole to plow through any lie and not get hung up.

The Uni-Rail or V-shaped sole works this way. First it minimized contact with the turf or grass which in turn increases the efficiency upon contact providing greater distance, directional control and feel.

Just ask yourself how many times you hit off of a perfectly flat lie? That’s what I thought, not as often as you like. While modern fairway woods and hybrids have rounded soles to help provide some relief the is still a limit where you can’t help but to hit off of the heel or toe on the sole and cause the head to turn and you ball to fly somewhere other than where you aimed. With the Uni-Rail sole, there is enough relief to acclimate to a 15 degrees elevation change such as the ball severally above or below your feet and still make solid contact.

Peace out to bad lies forever and see first hand how the Power Play Adrenaline’s Uni-Rail sole can improve your game.

Easy on the Pressure with Today’s Lightweight Shafts

The next time you go to secure a club in your vise, you should probably take heed to some advice – ease up on the pressure!  Unless you have been living under a rock for the past few years, shafts in general are becoming increasingly lighter and lighter in hopes that you (or your customers) will swing the club faster and get more distance.  This holds true not only with graphite or composite shaft, but steel shafts too.

To avoid a costly mistake, take a peek at the shaft or the club before you begin to work on it.  For example, if you see a big sticker on the butt end of the shaft that says “CAUTION: Please read before installing”, well that may give you first clue.

However a lot of the clubs you will be working on may be to simply re-grip or perform some other type of repair or to obtain a measurement on.  Take a second and examine the shaft.  Often times the name or writing on the silkscreen will help indicate the approximate weight of the shaft.  For instance a 55 in the name may be short for 55g.  Another example might be 43R, where the 43 most likely refers to the weight and R for the flex.

I say costly because it is important to realize neither shaft manufacturers nor the component suppliers are going to replace shafts that broke due to excessive clamping pressure.  In order to achieve these super lightweight shaft weights (below 60g in graphite and 90g in steel), the shafts are constructed with extremely thin walls especially in the butt half. However, they are designed to withstand the load or force over the full length of the shaft as it would be swung.  Durability testing is an important part of the development process as shaft manufacturers will error on the side of safety.

But there are many things that clubmakers or repair specialist may do to a club that can cause a shaft to crack or break.  Number one is clamping the shaft in their vise too tightly creating a longitudinal crack along the length of the shaft.  What you want to do if the shaft is very light, gradually build up the clamping pressure so the shaft is “snug” and will not move but not so tight that damage will be done.

Other activities that can render an expensive shaft useless in a hurry is placing one of these ultra lightweight shafts on a deflection board where all the load or force is concentrated on a single point or area rather than it’s full length.  This would also apply to clubmakers determining “spines” or conducting some sort of shaft orientation in whatever devise they have.

While lighter and lighter shafts will continue to be a trend, it will be the responsibility of the clubmaker or club repair specialist to take the extra care and avoid telling their customer that the $400 driver they just bought or $200 shaft they had retrofitted was destroyed trying to put on a grip.  Your reputation can quickly be tarnished and your wallet garnished in what an ounce of prevention could have taken care of.

Acer XF Irons Listed In Golf Digest “New Looks” Article!

The 2011 Acer XF Standard Irons were listed in the April, 2011 issue of Golf Digest’s article “Does Offset Make The Ball Go Higher or Lower”. The article states “It depends on the swing type…for golfers with more sweeping swings who cast the club offset plays a signficant role in bowing the shaft tip forward and adding loft right before impact…There’s no doubt in my mind that offset enhances forgiveness.”

The “New Looks” article then lists the Acer XF Irons as clubs that exemplify how a deep offset club offers unparalleled forgiveness. “The extra offset helps players square the face at impact and the topline is beveled to appear thinner. Less offset is available in the XF Pro Model. The standard has 6.8mm of offset,” states the Golf Digest article.

What Is a Ribbed Golf Grip?

In today’s market, golfers have a plethora of grips to choose from. They are offered in a multitude of materials, textures, firmness, styles and color combinations not to mention sizes so it is understandably that golfers can easily be confused by their subtle differences or by the terminology. One such term that I have been asked about recently is concerning ribbed grips. Not familiar with that term? Then you might be new to golf.

Why Ribbed?

Most golfers are only intimate with the outside of a grip as that is the only contact they have on a golf club. For those that re-grip their clubs or for others, or for someone that picks up a grip for the first time notices that it has a large opening at the mouth (bottom portion) and is hollow to allow it to slide over the butt end of the shaft. If you hold the grip up to your eye and pointed toward a light, one can see the inner portion of the grip. In the vast majority of the grips offered today the inner portion will be perfectly smooth.

The inner core of a grip can be designed with an internal feature than when placed onto the golf shaft will produce a pronounced raised rib in order to change the feel of the grip. This rib can aid in hand positioning. The term “reminder rib” is also used to describe a ribbed grip as it can help “remind” the golfer the proper position. This is permissible in the Rules of Golf for any non-putter grip. The raised rib must be straight, run along the full length of the grip and must not exceed a certain dimensional tolerance. If by chance you look inside the grip and see what looks like a flat side extending the length of the grip, it will be apparent that you have a ribbed grip.

Prior to 15 years ago, the vast majority of grips on the market were ribbed. Many grips at that time had very intricate patterns of paint fill that needed aligned so the grip didn’t look crooked when installed. If the grip was correctly aligned, then the rib would be positioned perfectly along the backside of the club (or 6 o’clock position). This would position the raised ribs in the fingers of both hands when held with an interlocking or overlapping grip.

Change of Buying Habits

In 1992, Lamkin introduced the Perma Wrap and Golf Pride the Tour Wrap, which looked liked simulated versions of leather wrapped grips. These grips where plain black and did not possess the intricate paint fill of so many of the grips at the time. For someone haphazardly installing the grips onto the shaft, this would lead to the rib being positioned anywhere but the traditional 6 o’clock position on the club. As these grips became overwhelmingly popular, soon the trend was for manufacturers and clubmakers alike to use the round or non-ribbed version of those grips to reduce the possibility of incorrect installation.

As time passed, people have become accustomed to requesting round grips, to the point where many golfers relatively new to the game may never have felt what a ribbed grip was on a golf club. Grip manufacturers have produced most of their popular models in both round and ribbed versions, even though many component supplies may choose to stock one or the other, rather than both. Often times in the catalog literature the component manufacturer will list whether or not the grip is round or ribbed.

What “Ribbed” Models does Hireko Offer?

Looking for a ribbed grip? Then Hireko has the largest selection to choose from in the entire industry in men’s and women’s (undersized) sizes plus corded models.

Meet the New Acer XF Driver Series – The Industry’s Most Comprehensive Line (Part 2 of 2)

In Part I we thoroughly discussed the Acer XF and XF Draw drivers, their benefits and who they are for.  In Part II, I want to go over the third version of the series – Acer XF Leggera.  Oh, by the way, Leggera means light in Italian and is a full 10 grams lighter than the standard version. Plus it is pronounced with a “je”, like “Lejjera” rather than with a “ge” as it looks.

Now there is one other feature that distinguishes it from the other versions and the reason why so many people gravity toward this particular model and that is the cosmetics. This version has a pearlized white painted crown which gives it a nice contrast and striking appearance.

Here is the kicker you just can’t magically take 10g from the head without any consequences.  If it were that easy, we would have done it a long time ago. That is why we incorporated a new proprietary thin crown technology. This special construction technique allowed us to remove weight from the only logical place that would not adversely affect the driver.  If you make the walls any thinner in the face and the driver becomes non-conforming.  Remove weight elsewhere and the center of gravity start to rise and diminish how high and far you can hit the ball.  Instead of robbing Peter to pay Paul, we ended up producing a highly playable ultra-light driver head at an affordable cost.

Now we got that out of the way, let’s get started to explain why you may want a lighter head.

It’s Black or White and No Grey Area

The decision to go to the Leggera over the standard version should be goal-driven.  For instance, did you pass the Meat Loaf test?  Remember, that is where you can hit 2 out of 3 fairways off the tee on average.  In that case, you have plenty of accuracy that you may be able to give up some in order obtain more distance.  Maybe you will gain back lost yardage that Mother Nature has taken from you with age.

Another reason golfers decide to purchase a new Driver is to get bragging rights and pound the ball further than they ever have before.  But how do you increase your distance without going to the gym and working out?  Here is the secret. The luxury that creating a driver 10g lighter gives is the opportunity to make the club an additional 1” longer and not feel too head heavy.  Therefore with the Acer XF Leggera we would encourage you to play this a minimum of 46” long.  The longer length provides additional leverage off of the tee.

Jaw Dropping Distance

The longer length coupled with the overall lighter head is the key to those jaw dropping distances that will make you the talk of your foursome.  The Leggera will be available in 3 right-handed lofts and 1 in LH, but right now only the RH 10.5º is available.  With the components available in our catalog and website, you could conceivable make a driver that weighs a mere 260g, which is a lot lighter than those nationally know brands touting their lightweight drivers.

Let’s look at the different scenarios at your disposal using the Leggera version.

Don’t get me wrong, the Leggera version is not for everyone.  For example if you slice the ball, like I said in Part I you would be far better off with the Draw version.  But remember, the Acer XF line has three distinct versions for each of the most common challenges that golfers face today. Now the challenge for you is to be honest with yourself and pick the right one for your game.  Regardless, you will have an eye-catching driver that will make you play your best golf.
