What shaft flex do I need?
Tell us your driver swing speed, or how far you hit it, and your tempo. We read your flex off the same speed bands our fitting uses.

- Your tempoand how it nudges the band
- The whole tablethe five speed bands, yours marked
Free. No account. No model writes the answer: it is the fitting’s own flex table.
How flex is chosen
One flex table, used everywhere on the site.
Flex is how much a shaft bends under load. Swing speed is the main guide to it, so our fitting sorts every golfer into one of five speed bands and offers the shafts that come in a flex in that band. Tempo then moves you one band stiffer or softer inside the options a shaft has.
The letters are L (ladies), A (senior), R (regular), S (stiff) and X (extra stiff). Brands label their own flexes differently (R2, SR, TX and so on), so our fitting maps each shaft’s labels onto this scale and checks the options that shaft really offers. A full fitting also picks shaft weight and kick point, which this page does not.
What flex should I use for my swing speed?
Shaft makers and fitters group swing speeds into bands, and each band points to one or two flexes. Our fitting uses five bands, shown in the table above, and they overlap on purpose: a golfer near the edge of a band suits either of its two flexes. Use the band as a starting point, then check it with a launch monitor, because a shaft's feel and your strike matter too.
Does tempo change my flex?
A little. In our fitting, an aggressive tempo moves you one band stiffer and a smooth tempo one band softer. A moderate tempo stays in the band for your speed. At the ends of the scale the band cannot move any further.
Is iron shaft flex the same as driver flex?
The bands are the same. Our fitting reads iron shaft flex off your driver swing speed, using the same table, so the answer here applies to irons as well. Treat it as a guide, and have a fitter confirm it with your irons in hand.
