Frequency matching shafts only measures the butt flex of the shaft and allows the club maker to perfectly match a set of golf clubs. It is up to the club fitter to match a shaft to the golfers swing needs. Golf shaft manufacturing processes, while having improved by leaps and bounds, are still imperfect.
What is the frequency of a golf shaft?
Frequency is defined as the shaft “flex feel” of each club to the golfer. It is determined by the flexing characteristics of the club shaft. Frequency is a proven and accepted method of club assembly.
What is a frequency matching shaft?
Frequency matching shafts only measures the butt flex of the shaft and allows the club maker to perfectly match a set of golf clubs. It is up to the club fitter to match a shaft to the golfers swing needs.
What is true frequency matching in golf clubs?
True professional clubfitters and master club builders understand the importance of “frequency matching”. To find any shaft’s true frequency, the shaft is placed in a clamp with the clubhead dry fit on the end of the shaft. Then the club maker pulls the shaft to make it oscillate.
What is the difference between flex and frequency in shafts?
It is important to realize that there is no flex standard in the golf industry. Frequency provides an absolute way to measure the stiffness of a shaft. Shafts can then be matched to a player’s swing to improve performance. Frequency offers the ability to duplicate a favorite club, a demo club or a friends’ club that the player hits well.
What does frequency golf shaft mean?
cycles per minuteMar 9, 2009. Frequency is an absolute measure of the flex of a shaft. It is defined as how many times per minute a shaft oscillates. The units of frequency measurement are known as cycles per minute, or cpm. A shaft with a higher frequency is stiffer than one with a lower frequency.

What is CPM frequency?
Shaft frequency is a precise method of measuring shaft flex. Cool Clubs determines frequency based on the length of the club and the units of frequency measurement known as Cycles Per Minute (CPM). A shaft with a higher frequency (more CPMs) is stiffer than one with a lower frequency (fewer CPMs).
What does CPM mean in golf shaft?
cycles per minuteSimply put, CPM stands for “cycles per minute,” which measures the frequency of a golf shaft. To obtain this measurement, a fitter or club builder places the grip end of a golf club into a clamp, then pulls on the tip section of the shaft and releases it to make it oscillate.
How do you determine the flex of a golf shaft?
Some General Guidelines About Shaft FlexTake a look at the distance you hit your driver. ... If you have a very smooth swing, you might benefit from a softer flex even if you swing fast. ... If your drives go left, you might benefit from a stiffer flex; if your drives go right, you might benefit from a softer flex.
What does frequency matched mean?
Frequency matching is a sampling design used in case–control studies to assure that cases and controls have the same distributions over strata defined by matching factors.
How many CPMs are there between each flex?
CPM (Cycle Per Minute) Tolerance: Others, like MATRIX, are very specific about CPMs and assign a range of 4 CPMs to each flex, i.e. Regular flex, 6M3 is 241-245.
What does FCM mean in golf?
The FCM system or Frequency Coefficient Measurement (system), is a Brunswick / Royal Precision invention by Braley (designer of RIFLE FCM) and Kim Braley (designer of Project X -now KBS shafts).
What is CPM vibration?
CYCLES PER MINUTE (CPM): In vibration analysis, cycles per minute refers to the number of vibratory cycles that occur in one minute of time. Cycles per minute is a quantity of frequency.
What is a good CPM?
On average, a good CPM is $1.39, $1.38, $1.00, $1.75, and $0.78 for the telecommunications, general retail, health and beauty, publishing, and entertainment industries, respectively.
What does it mean if CPM is high?
A high CPM score typically tells you that you're running a weak campaign and there's room for improvement to boost your ad views. If you've been keeping an eye on your CPM and are wondering why your Facebook ads have such a high CPM, there are some contributing factors at play, too.
What causes high CPM Facebook?
It's basic supply and demand—the more narrow and in-demand an audience, the higher the CPM.”
What is CPM in FB ads?
CPM (cost per 1,000 impressions)
How to measure shaft frequency?
To get a shaft frequency measurement, the shaft is clamped at the grip end. The other end (the clubhead end) is pulled down, then released.
What is frequency matching?
Frequency matching is a service provided by some custom clubmakers or club fitters that helps ensure the ideal gapping from club to club within a golf set in "shaft frequency measurement." We'll explain what that is below.
How important is frequency matching?
How important is frequency matching? For most golfers, not very: it trails well behind shaft weight, flex rating and bend profile in importance for all golfers. It does matter at the margins, however, and so, relatively speaking, is more important to the best golfers than it is to most golfers.
Does frequency matching help golfers?
But, Wishon said, frequency matching trails multiple other shaft factors in importance: "If the shaft weight, shaft flex and bend profile are not fit properly to the golfer, frequency matching will not help the golfer. It is far more important to properly fit the weight, flex and bend profile to the golfer than to worry about frequency matching in ...
Do You Need to Worry About Frequency Matching?
The goal of frequency matching, Wishon said, is to "make the progression of grip-end stiffness from club to club more consistent from longest to shortest clubs in a golfer's bag."
What is frequency matching in golf?
It is important to realize that there is no flex standard in the golf industry. Frequency provides an absolute way to measure the stiffness of a shaft. Shafts can then be matched to a player’s swing to improve performance.
What is the measurement of the flex of a shaft?
Frequency is an absolute measure of the flex of a shaft. It is defined as how many times per minute a shaft oscillates. The units of frequency measurement are known as cycles per minute, or cpm. A shaft with a higher frequency is stiffer than one with a lower frequency.
How to find the frequency of a club shaft?
To find any shaft’s true frequency, the shaft is placed in a clamp with the clubhead dry fit on the end of the shaft. Then the club maker pulls the shaft to make it oscillate. This oscillation is measured in cycles per minute (cpm’s). The faster the shaft oscillates the stiffer the shaft is said to be.
What type of shafts do golf clubs use?
The build of your set of clubs is just as important as the fit. Just ask any Tour player. At KZG we only use parallel tipped shafts which are designed so that a club builder can perfectly match your set of golf clubs to a tolerance of +/-1cpm. By trimming a little more or less off the tip end of the shaft they can achieve the perfect flex on each golf club. Taper tipped shafts, which are used by all of the big manufacturers, are designed to be mass produced and dropped into a particular club’s head and the cut to length i.e. a 9 iron shaft for a 9 iron head. These are difficult if not impossible to match perfectly.
What is a taper tipped shaft?
Taper tipped shafts, which are used by all of the big manufacturers, are designed to be mass produced and dropped into a particular club’s head and the cut to length i .e. a 9 iron shaft for a 9 iron head. These are difficult if not impossible to match perfectly.
Is golf shaft manufacturing imperfect?
Golf shaft manufacturing processes, while having improved by leaps and bounds, are still imperfect. This means that if you go to the local golf retail store and buy a set of “off the rack” clubs and later get the shafts measured for frequency, you will find that the vast majority of those sets will not match.
Do two different types of shafts measure at the same frequency?
This, however, does not mean that two different types of shafts which measure at the same frequency will play the same. Shafts have different bend profiles – which means they are stiffer or softer in different areas of the shaft.
Do you need to contort your swing to suit your KZG golf clubs?
Each club in your bag will then “feel” and perform the same … no need to contort your swing to suit your clubs!
Why is frequency important in golf?
This allows a golfer to swing each club in their bag with the same tempo. The goal is to achieve maximum clubhead velocity at impact for ideal ball flight.
What does flex mean on golf shafts?
All shaft manufacturers design their shafts to produce certain ball flight results and to a specific “flex feel”. Typically, shaft manufacturers label their shafts’ flex designation with a letter L-A-R-S-X or a word like FIRM, SOFT of STIFF. The frequency of golf shafts is measured in Cycles Per Minute (CPM). The higher the CPM, the stiffer the shaft.
How to determine flex of golf clubs?
Understanding the true flex of clubs is made possible by measuring and comparing each shaft’s frequency in a set of clubs to the desired gradient on a chart. The gradient can vary with different shaft designs and geometry. That’s why it is important to know how the shaft’s geometry relates to a golfer’s “feel”.
How to determine club flex?
The best way to determine club flex and the frequency of a set of clubs is by using The Mitchell Golf DigiFlex 2.0 Frequency Meter. The Frequency Meter makes multiple measurements and averages these measurements over a defined period of time. This is done to calculate frequency and ensure accuracy and reliability. Our machine also uses the horizontal method of measurement rather than the vertical method used by most competitor systems. By measuring horizontally, the DigiFlex 2.0 greatly reduces the effects of mass at the end of the shaft.
What is frequency used for?
Frequency is also used to match a shaft when replacing a broken shaft. It is used to determine the flex of a golfer’s favorite club for building other clubs with similar shafts. It can also be used to measure the symmetry of a shaft.
Is there a flex standard in golf?
We’ve made this point often, but it is one that is worth repeating: There is no flex standard in the golf industry today. Frequency provides an absolute way to measure the stiffness of a shaft. Once this is determined, shafts can then be matched to a player’s swing to improve performance. And better performance always makes the game more enjoyable.
Is there a standard for shaft stiffness?
However, there is no clear standard of shaft stiffness in the industry. The typical result is that most club’s flex designations don’t play to the specs represented on the label. Frequency can be used to compare these different designations for the actual “feel” best suited for individual golfers.
What is frequency in golf?
Frequency is defined as the shaft “flex feel” of each club to the golfer. It is determined by the flexing characteristics of the club shaft. Frequency is a proven and accepted method of club assembly. Which can provide golfers with a set of irons or woods that will best control trajectories. The “frequency” of an assembled club is measured in CPM (Cycles Per Minute) on a special machine called a “frequency analyzer”.
What is a club frequency analyzer?
A club frequency analyzer measures the stiffness of shafts through what is called “shaft frequency measurement”. This pertains specifically to club oscillation. The stiffer the shaft – the faster the rate of oscillation. The more flexible the shaft – the slower the rate of oscillation. The frequency analyzer is designed to count the oscillation rate in the form of “cycles per minute” (a numerical value of CPM’s). CPM’s provide a concrete data comparison between different shafts as well as industry standard benchmarks.
Why Test Frequency?
We test for frequency, because not all shafts that are marked “stiff” are really stiff. Consequently, not all shafts marked “regular” are necessarily regular. This is true for all of the “stiffness” letter markings. The inconsistency can occur with both graphite and steel shafts, however, it appears more prevalent with graphite shafts.
What is stiffness in golf?
It involves a club set made with the incremental increases in frequency from longest to shortest clubs in the set. Consequently, the “stiffness” will be precisely feel the same from club to club.
Does frequency affect shaft height?
However, due to many factors, the amount of increase from shaft to shaft is not normally in the exact same increment. Frequency does not pertain to club height. It directly applies to shaft flex and the rate of oscillation as measured in CPM’s because that is what the analyzer measures.
Does a frequency match work for a shaft?
We do offer this frequency matching service along with properly fitting shaft weight, flex, and bend profile. Our machine analyzer is a valuable tool to consistently measure shaft frequency. It works for both assembled clubs and raw shafts. Frequency Matching does differ from MOI Speedmatching and Shaft Puring. Albeit, these topics are often intertwined and misunderstood.
Why Frequency Matters
Cool Clubs measures frequency — and a host of other variables — through our industry-leading S3 Technology ( learn more about S3 here) instead of relying on the catch-all term “flex” to gather precise data that is not available anywhere else.
All Golfers Benefit
Have no fear, 15-handicapper! It’s not just average players who have this trouble. PGA TOUR professionals have issues with their golf shafts all the time.
What is L A R S X in golf shafts?
There is no industry standard as to what is L A R S X in a golf shaft. The club builder can use a frequency meter to test the oscillations of a raw shaft with a weight consistent with a driver weight or heavier iron head. This measurement is a baseline to match flexibility with a golfers swing characteristics.
Is frequency useful for shafts?
Using frequency to compare different weight and length (not to mention profile) shafts in driver s for example is pretty much useless. When it comes to building clubs, there is only one flex to consider - the one that fits the player. What that specific flex category (such as R, S, X etc) or indeed CPM that may be is irrelevant.
Is frequency a relative shaft flex?
Frequency is often confused with relative shaft flex but essentially they are two different things.
Who first discussed shaft oscillation frequency?
The concept of using shaft oscillation frequency was discussed in the 1968 book, “Search for the Perfect Swing” by Alastair Cochran and John Stobbs. “Search for the Perfect Swing” is one of the first explorations of golf technology.
Who invented the rate of oscillation of a shaft?
Dr. Joe Braly introduced club makers to using the rate of oscillation of a shaft (frequency) to understand its stiffness. In the 80’s he did research on the PGA tour. He used a frequency instrument to measure the shafts used by the tour players. From this research, he developed a formula for the stiffness of ratio of the different irons in the set. The ratio he found was 4.3 CPM (cycles per minute) per one half inch of length of club.
What is PCS in golf?
Inspired by the research done by the Braly’s, a club makers organization, the PCS, endorsed and taught frequency based club making to its many, many members. it was a time when shaft design was not as complex as it currently is and when frequency instruments were one of the few tools available to club makers for measuring shaft stiffness.
Is shaft frequency used in stiffness?
Shaft frequency is not of much use in evaluating shaft stiffness. The problem for club makers and fitters who recognized the importance of shaft profiling was that there was not an affordable EI instrument until I designed and manufactured one. They used the frequency instruments they had. As with all technologies, instruments and expertise evolves. Frequency profiling and frequency rating of shaft stiffness were an attempt by club builders to reverse engineer shaft knowledge not shared by the shaft companies. Affordable EI instruments have closed the knowledge gap between the shaft engineer and the club fitter.
Who owns Royal Precision shaft?
The Royal Precision shaft company was purchased by True Temper and with that purchase was the numeric stiffness rating patent. Here is a look at how that system is currently applied.
Do golf shaft stiffness rates work across brands?
The systems we have to rate golf shaft stiffness do not work across brands or even across models within brands. Most experienced club fitters use their experience to understand golf shaft stiffness. Many use some systematic method, most often frequency, to rate the shafts they work with.
