What is shaft flex in golf shafts?
Shaft flex is the degree to which the shaft will bend or flex during the swing. A more flexible shaft bends easily during the swing and has the potential to produce a longer-ranged shot. Although, choosing the most flexible one will not improve your accuracy as it tends to twist more.
What are stiff shafts in golf?
X-stiff – This is the range where most high-level players fall. If you’re swinging the driver above 105 mph, it might be time to get some X stiff shafts in your set. Stiff – This range is still considered fast, but you most likely won’t be out on Tour anytime soon.

If you are not certain or in between flexes, it is better to select a softer flex than a stiffer one. In addition, if you slice, a softer flex may help to correct the problem. The flex in a golf shaft affects the distance, accuracy and trajectory of your golf shot.

What is stiff shaft?
Stiff Shaft. The stiff shaft is quite popular and should be chosen by those who consistently drive the ball 250 or more yards off the tee. This shaft generally appropriate for mid-low handicaps, but be sure to have your clubhead speed measured before choosing between a stiff and regular flex.
How does flex affect golf?

Women generally have the lowest club speed of all golfers and should select a ladies flex. This is the softest of all the flex ratings. If you consistently hit the ball less than 200 yards off the tee , this is an appropriate flex. Women who hit further may want to consider either senior or regular flex clubs.
What happens if your golf shaft is too stiff?
It is important to note that if you select a shaft that is too stiff, you will lose loft and control on your shots.
How many flex ratings are there for golf clubs?
There are five flex ratings for golf clubs--extra stiff (X), stiff (S), regular (R), senior (A) and ladies (L). Generally, the faster your club speed, the stiffer the shaft, but use care when selecting a flex. If you are not certain or in between flexes, it is better to select a softer flex than a stiffer one.
How to determine golf shaft flex?
Start by using a launch monitor to analyze your golf swing speed. If your swing ranges between 85 mph and 95 mph then you should start with a regular flex. If your swing speed is faster than 95 mph, then you should try a stiff shaft.
What shafts do golfers use?
For most golfers, a graphite shaft works great. Most iron sets are made with graphite shafts as well so you get that material type by default usually unless you specifically seek out steel shafted irons. With steel shafts, you may find that golf shots are easier to control.
What is the best shaft for golf?
Steel – A steel golf shaft is usually stronger and more durable (less likely to snap) than a graphite shaft. It’s also less expensive and sometimes stainless steel is used in the creation of the steel shaft. There is also two variations, stepped steel and rifle steel.
Why does my golf shaft have a slice?
When the golf shaft is too stiff, it doesn’t unload properly at impact. This can lead to the face staying open and result in a slice golf shot. Beware, a slice isn’t always an indication the shaft is too stiff so if you already have a slice, it could be caused by another fault in your golf swing.
Why do golf clubs have shafts?
During the golf swing the shaft causes deflection (bend) that causes the clubhead to be in a forward and toe downward position relative to the grip of the club.

What to know about golf shafts?
In today’s guide we will review everything you need to know about golf shafts. Picking out the proper golf shaft is very important as it will impact several components of your golf swing. For example, picking the wrong golf shaft flex can cause you to hook or slice the golf ball. It also can hinder the total distance the ball flies by having too much spin or too low of launch. But don’t worry, at the end of reading today’s guide you’ll be much more educated on the buying process and how to pick out the right golf shaft. Lets Get Started!
What is shaft in golf?
But shafts are an element part of your game. The golf shaft connects you with the club head and transfers massive amounts of energy. This energy in combination with the properties of your equipment causes several movements of the club head in different directions during the course of the swing.
What is 1/4 of the vibration period of a golf club?
Physics tells us that 1/4 of the vibration period of a club is the time it will take for the club head to return to the square position. Working with a club-fitter who can measure the dynamics of your swing (how and when you release and how fast you swing), can help determine what this time period exactly is, and thus what would be ...
Why is flex misleading?
Flex can be somewhat misleading however because the actual measurement of the stiffness of a shaft is in the frequency. The frequency of a shaft is the number of cycles per minute a shaft will oscillate when one end is fixed (clamped) and the other end is pulled down with a weight attached to it. Ideally a flex (such as Stiff, Regular, ...
What happens during the downswing of a golf club?
But what really matters in the end is the golf club frequency as a whole. At the start of the downswing, you are accelerating the club to gain speed. During this period, the shaft will bend, causing the club head to lag behind your hands and body.
How to know if your club head is square?
You can check to make sure your club head is square if you were to draw a line between you feet and the plane of the face of the club is perpendicular with the line at impact. If the face were open or closed, then your swing will likely result in a sideways trajectory. When your club frequency (as a whole, not just your shaft) ...
What are the ratings for shaft flex?
There are five generally used ratings for shaft flex: Extra Stiff, Stiff, Regular, Senior and Ladies, usually denoted by the letters X, S, R, A and L ("A" is used for Senior because this flex was originally called "amateur").

Why is softer flex better for macho men?
Choosing a softer flex often has the effect of forcing macho men to slow down their swings. And slowing down the swing often makes those macho men into better golfers. And the fact is, the harm in hitting a shaft that is too flexible is much less than the harm in hitting a shaft that is too stiff.
What shaft do you need for a jerky swing?

Is there a standard way to measure flex?
Given that there’s not a standard way of measuring flex, you can correctly assume that there is no standard for labeling flex either. What one manufacturer calls “stiff” might be “regular” to another. This is why they universally emphasize the importance of fitting.

While they didn’t agree on much, every shaft manufacturer that we spoke to said that flex is only one part of the equation . MRC noted that torque values will vary widely from model to model, and that has a big impact on performance.
How to choose shaft flex?
These are just general guidelines, however; the best way to choose shaft flex is to go through a club fitting. Not every golfer can (or is willing) to do that, though.
Why do golf shafts bend?
Shaft makers vary the amount of stiffness because golfers have different types of swings—different swing speeds, different tempos—and different amounts of stiffness in a shaft better match up to those different swings.
What happens if you mismatch your golf shaft?
If your swing is mismatched to your golf shaft flex—if you are using an X flex shaft, for example, when you should be using an R flex shaft—you will have a harder time squaring the clubface at impact. The way your shots are flying can clue you into the possibility you might be using the wrong flex.
When were steel shafts invented?
Alas, no. Golf industry veteran Tom Wishon, of Tom Wishon Golf Technologies, explains: "Shortly after steel shafts were introduced in the 1920s, steel shaft makers discovered they could change the diameter and wall thickness of the tubes to create shafts with different amounts of stiffness to better match to the different swing speeds ...
What does it mean when a golfer's swing is slower?
The slower a golfer's swing, generally speaking, the more flex he or she requires in the shafts that are in their golf clubs. And the faster the swing, the more stiffness. Tempo also matters: A jerkier swing requires more stiffness, a smoother swing less stiffness, generally speaking.
