Welcome to another edition of the Fully Equipped Mailbag, sponsored by Cleveland/Srixon Golf, an interactive GOLF.com series in which we field your hard-hitting gear questions.
I’ve played golf for 25 years and have whittled my handicap down to single digits. But even after all this time, I still have no idea how a composite shaft works and can’t make sense of the marketing. Is it me, or is it a normal thing to not understand it all? – Mike P., California
Perfectly normal, Mike.
Shaft science is arguably the most complex aspect of golf equipment technology. Shafts are often referred to as the “engine” of a golf club, and there is a lot happening in the shaft from the moment you start swinging until you make contact with the ball.
At first glance, some things appear straightforward. For example, the weight of a shaft seems like a simple concept – lighter shafts are typically easier to swing faster. However, did you know that a lighter shaft can make your clubhead feel heavier and increase swing weight? Additionally, adding weight to the grip end of the shaft can make a club feel lighter as you swing it and reduce its swingweight. Crazy, we know.

Flex is another aspect of shafts that can be confusing for golfers. It was previously assumed that the faster you swung the club, the stiffer the shaft should be. That’s still partly true, but what really matters is how you load the shaft during the onset of your downswing leading up to impact with the ball. For example, golfers with fast overall swing speeds may have slower transitions from the backswing to the downswing, so they may not always want a stiffer shaft. On the other hand, golfers with average swing speeds at impact may have quick or jerky transitions, thus requiring a stiffer shaft for better results.
Where a shaft flexes is also critical. A shaft can have a kick point in different places, such as high kick points that limit spin and produce lower ball flights, low kick points for higher launches with added spin, or sometimes a midpoint kick for a mid-launch/mid-spin launch.
Shaft technology becomes even more complicated when you factor in how a shaft twists as you swing. Low-torque shafts resist twisting more, helping faster swingers hit straighter shots with more control. They also have a firmer, more rigid feel. Conversely, higher torque shafts benefit slower swings by making it easier to square the face at impact and feel softer and smoother. They can sometimes help slower swingers gain a few extra yards, too.
