How is golf shaft stiffness measured?

Like Stuart sais, "flex" (flex letters), cant be used since thats not what those letters is for, they are only a address in that shaft models weight class, noting else, so butt CPM or FCM is way better, but we ONLY get a starting point for testing.

What is a cpm?
cpm (cycles per minute) is one way to measure the stiffness of a shaft. 10 cpm equals one full flex, let's say from s to x. With 280 cpm (depending on shaft length and swingweight) your driver seems to be extra (X, probably more) stiff. Going to 275 would make it half a flex softer.
How much bore-thru for titleist drivers?
Correct. Titleist drivers have a bore-thru of about 3.5". (TM blind bore's are only 1.5" to 1.75 inches!!!) 3.5 inches is so much it not only changes the flex drastically, it also changes the characteristics of a shaft. Fuji for instance has a 3 inch long protective sleeve build into the tipps of all their shafts. This alone gives you an idea how much the Titleist bore-thru can change a shaft. (and the reason why Fuji built that Titleist Speeder shaft.) Because of this most Pro's (Titleist does it too) turn it into a blind bore, by leaving a false tipp (cut-off tipp from an old shaft) at the bottom of the bore-thru. Makes it so much easier to keep the flex under control.
Category 1: 210 to 250 CPM
This category ranges from extremely light and soft 45g shafts to common 65g shafts. The club head speed should be below 105mph. However, it is impossible to make a general statement because every driver swing is very individual and it also plays a big role how a player "loads" and "releases" a shaft. Therefore, this value is only a rough guideline.
Category 2: 250CPM and up
In this category you are (usually) with roughly about 105mph clubhead speed. And up to about 120mph you have a relatively wide choice of shafts in the 60 to 75g range.
