The Importance of Shaft Flex
Learn how to unleash "stored-energy flex"
By Steve Divnick
Shaft flex is much more than its specifications.
Significantly, it depends on your swing speed, how the shaft is trimmed (tip or grip-end) and on the weight of the head. For instance, a heavy head can turn a stiff flex into a regular.
Our flexes are specifically designed for our industry-low super-light heads. This allows for a lighter shaft and overall lighter club for faster club-head speed.
"Swinging fast" does not mean the club head is "moving fast". Club head speed is a matter of timing and tempo.
Some golfers with the slowest, most graceful swings are able to achieve fantastic club-head speed at contact. That is the only moment during a swing that you want speed.
Ernie Els is a perfect example. The "Big Easy" has an effortless swing. It just doesn't look like that smooth motion should be able to launch the ball over 300 yards.
But his swing unwinds smoothly until the club head is at maximum speed at the moment of impact. The key words are "unwinds smoothly."
If you can master that concept, you will add more yards to your swing than any piece of equipment can provide, including our drivers.
Think of it like snapping a towel. Your hand, arm, and most of the towel are not moving very fast at all. But because of the length and leverage, the towel unwinds faster and faster as it changes direction and the tip snaps so ferociously it makes a loud explosive POP. But it is not moving very fast until that last fraction of a second.
Try getting the towel to snap by flailing your hand away from your body and jerking it back as fast as you can. It doesn't work. The towel never has a chance to fully extend or unwind.
In fact, when you snap a towel, the more gracefully you make the transition from out-to-in, the louder and crisper the POP.
Similarly, a fast golf swing doesn't achieve much more than a fury of motion and inconsistent results.
A golf swing should unwind smoothly from the feet through the legs and hip-turn, with the arms and wrists gaining speed very gradually and smoothly until the head of the club snaps through the ball at impact. Everything up until that point should be slow and smooth.
A flexible shaft, properly swung, is like the end of that towel with a titanium tip. It will ignite the ball off the tee and cause people to exclaim, "Wow, how do you hit it so far with such a smooth swing?"
The great thing about a shaft is that it has "stored-energy flex". A towel doesn't. A shaft is a great equalizer. It allows a small player to compete with a tall player. It allows someone with a slow swing to compete with an athletic golfer.
The flex, all by itself, can accelerate the club head speed an amazing amount, IF you give it a chance. You don't want to over swing a shaft because that prevents it from snapping through the ball.
Another great example is shooting a bow and arrow. If you tried to throw an arrow with your arm, you probably couldn't throw it more than about 30 yards, if you are athletic. You just can't move your arm and wrist any faster. But when you introduce an extension of your arm, and it has stored energy in the form of flex, you can "throw" the arrow 10 times that far. TEN TIMES AS FAR!!! Yet, you are not using any more strength than you use when you try to throw it by hand.
Here's the secret: Stored-energy flex multiplies the human body's potential. But only if you let it flex and then snap through. If you use a shaft that is too stiff, or if you overswing it so it can't snap, you will NOT be able to multiply your potential nearly as much.
LET THE SHAFT DO ITS JOB. LET IT SNAP. A shaft will accelerate the head much faster than the strongest, most athletic pro on the PGA circuit.
"The shaft performs the finale in the symphony of your swing."
To slightly change the famous saying of the 26th President of the United States , Teddy Roosevelt:
"Swing softly and carry a BIG STIK!"
