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.
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.
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 is the most common shaft material used in golf clubs?
Graphite Shafts. Graphite – this type of shaft is usually lighter weight compared to a steel shaft but it’s less durable and more expensive to make. Graphite is one of the most common shaft types used in golf clubs and can arguably be considered the main shaft material used, beating out steel.
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, ...
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 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.

As said. There are no industry standards. Over the years there have been attempts but generally the marketing types step in and stop the engineering types from doing so. Marketing types want flashy slogans, etc., not apples to apples comparisions.

Miyazaki IS standardizing shaft flex. Would it be more accurate if they used a 0-100 scale instead of a 0-9 scale? Yes. Would it be more accurate if they measured 100 points along the shaft instead of 4 points? Yes. With that being said, I think the flex code ratings are very useful to get general playing characteristics of shafts.

I should also mention there are separate codes for bending profile and torsional profile. So....good old flex category and torque figure it is then.
Super Tuna
What also gets missed in that report is they tell us part of how they tested each shaft to get the numbers. They are generate after having it installed on a TL310 head at 45 and 1/8th of an inch for a finished length then measure the 4 points and classify the general launch angle.

Right now it's the best universal system out. The shaft PDF on Cleveland's site uses the IFC on a number of shafts. Sure we don't know how they perform the testing, but it gives us a realitive basis to compare shafts.
