Are Your Shafts Right For You?…or How Much Do You Know About Oscillation Frequency?

  1. Shaft frequency (flex) is a number. NOT a letter.
  2. Your personal shaft profile includes flex, length, weight, and kickpoint.
  3. Unless or until you have an experienced professional perform an MRI on your whole bag, what you don’t know is a lot.

You’ve been playing with them for years and you’ve never had a reason to doubt them. You’ve always assumed that they were being true to their word. But — deep down — how well do you really know them? Can you really trust they’re what they say they are?

No, we’re not talking about the guys in your weekly foursome; we’re talking about your clubs.

One of the things that sets ClubCraft® apart from just about every clubfitter out there is the meticulous speccing process we perform on your clubs even before we start talking about new builds.

For a lot of people, this comprehensive assessment is truly a lightbulb-going-on-over-the-head moment. It might actually be the most eye-opening half-hour of your golfing life. We take every club in your bag and determine things like its actual loft, lie, length, and swing weight. Perhaps, though, the most alarming part is when we get to shaft stiffness.


We use a frequency analyzer to precisely determine how stiff your shafts are. It gives us the cycles-per-minute (cpm) that the shaft oscillates at. This number lets us see exactly where on the stiffness spectrum things really are. It’s the most reliable way to determine your shaft’s actual stiffness. Unfortunately, though, a lot of times, this number doesn’t correspond to the X, S, R, A, or L on your shaft.

With mass-produced clubs shaft stiffness can be imprecise. Mass market shafts are produced in greater volumes and this can make it more difficult to maintain strict quality control.

Shafts made in smaller batches tend to have less inconsistencies in terms of how stiff they’re supposed to be and how stiff they actually are.

Regardless of the manufacturer, all the shafts we use for builds at ClubCraft are produced in small quantities. These are of a higher quality and are a lot truer to their X, S, R, A, and L ratings.Of course, manufacturing isn’t entirely to blame. If you’re a shorter golfer or a taller golfer, that same shaft — in a shorter or longer version — isn’t going to have the same stiffness of the stock-sized shaft.


As with everything about your clubs, shafts need to be in tune with your swing and your body. If we’ve determined that the shafts you’ve been using are either too stiff or not stiff enough, it can be a real game-changer when you start swinging clubs built with shafts that are more in line with your current game. Your most common “misses” suddenly disappear. It may seem like magic, but it’s pure science.

The fact is that golfers would be far more knowledgeable about their shafts if they were rated by a numeric value instead of just a letter.

It might work for coffee and pizza, but just imagine if shoes and pants were only available in small, medium, or large. A lot of us would be walking around in some ill-fitting stuff. Unfortunately, that’s what a lot of us are doing out on the golf course — walking around with some ill-fitting clubs.

Since it’s unlikely that manufacturers will be switching to a numeric rating from a less reliable letter rating in the foreseeable future, you may not know as much about your clubs as you think you do. At ClubCraft, our detailed speccing process takes the mystery and ambiguity out of what’s currently in your bag. You’re going to play your best when your shafts and clubs are in line with your swing and your body.

Let ClubCraft help you take your game to the next level.
