What does CPM mean in golf shafts?
Cycles Per Minute
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).
How many CPMs are there between each flex?
Regular flex shafts, denoted R, measure approximately 240 CPM.
Is a 6.0 shaft Stiff?
Have you ever wondered what the number designation on your Project X shaft means? You know, the 5.0, 6.0, 6.5 and so on printed on the shaft. These numbers correspond with flexes from “regular” to “extra stiff plus”.
What does a 5.0 shaft flex mean?
Regular – 5.0. Regular Plus – 5.5. Stiff – 6.0. Extra Stiff – 6.5. Extra Stiff Plus – 7.0.
How is shaft stiffness measured?
Today, frequency analyzers are commonly used as another way to define the stiffness of a club by clamping the butt end and plucking the head to put it into motion. The frequency analyzer measures these movements and calculates how many cycles per minute (cpm) the shaft would oscillate over the sensor.
What shaft flex does Tiger Woods use?
Q: Does Tiger Woods use Regular or Stiff Shafts? Tiger Woods consistently hits distances of more than 305 yards. In most cases, he uses a regular shaft for his driver. Now, this does not mean that you switch to regular shafts because Tiger Woods is doing so.
How do I know what flex golf shaft I need?
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 happens if a shaft is too stiff?
Two Main Effects of a Too-Stiff Golf Shaft Stiff shafts tend to impact distance, resulting in shorter distance. A shaft that is too stiff will absorb the force of the swing, which affects the timing of the transference of energy from the club to the ball at impact. The ball tends to fly lower, which impacts distance.
What is a good swing speed for a 7 iron?
An average golfer will swing a seven iron about 75 mph. This number can change based on the weight of the club and if it is steel or graphite. The faster you swing a seven iron, the further it will go. If you can swing at about 85 mph, you will see distances closer to 165 yards.
What happens if golf shaft is too stiff?
A shaft that is too stiff will absorb the force of the swing, which affects the timing of the transference of energy from the club to the ball at impact. The ball tends to fly lower, which impacts distance. If a player has a faster swing speed, they can actually benefit from a golf shaft that is a bit stiffer.
What kind of shaft should I use for my driver?
When it comes to picking a graphite shaft for your driver or fairway woods, the number of choices that are available can be overwhelming, especially as golf companies continue to offer more and more in the way of custom options.
What to expect if you choose the wrong Golf driver shaft?
This chart is designed to give you a basic guideline for most golf driver shafts. What can you expect if you choose the wrong golf shaft flex for your unique golf swing? 1. Too stiff – You are playing a golf driver shaft flex that is too stiff. What can you expect? Your trajectory will be low and to the right with a loss in distance potential. 2.
What are the numbers on a golf shaft?
Brunswick shaft company patented a numbering system 4.0, 4.5, 5.0, 5.5, etc. The golfer was and still is confused about these numbers. The club making community made their own attempt at creating a standard. To date, the only standard is confusion.
How is the stiffness of a golf shaft measured?
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.
