Reading a Shaft Spec Sheet Correctly
Flex, weight, torque, and material all shape how a shaft performs — and each one is really just another column that has to line up across your whole set matrix, not a number to pick in isolation.
A Relative Label, Not a Fixed Standard
Flex ratings (Ladies, Senior, Regular, Stiff, Extra Stiff) aren't standardized across manufacturers — a "Stiff" shaft from one brand can play noticeably differently from a "Stiff" shaft from another. Flex is better understood as a description of how much a shaft bends and releases relative to your swing speed and tempo.
A shaft too flexible for your swing speed can cause inconsistent face angle at impact and excess spin; too stiff, and you may lose feel and struggle to load the shaft at all.
Steel vs. Graphite vs. Multi-Material
Steel
Heavier and more consistent shaft-to-shaft, offering precise feedback and control. The standard choice for iron and wedge rows in most matrices we build.
Graphite
Lighter weight raises swing speed for players who benefit from it, and dampens vibration for more comfortable feel. Standard in drivers, fairway woods, and hybrids.
Multi-Material
Combines a steel tip section with a graphite body to blend feel and consistency with reduced weight — a growing option in iron rows for slower-swing-speed players.
The Numbers Behind the Flex Label
Torque measures how much a shaft twists under load — lower torque generally means a more stable feel for faster, more aggressive swings, while higher torque can add feel and a softer release for smoother tempos.
Shaft weight interacts with flex more than most golfers realize, and it's one of the columns we check for consistency across every row of your matrix: a lighter shaft in the same flex rating will generally play softer, while a heavier shaft in the same flex plays firmer.
| Shaft | Weight | Torque |
|---|---|---|
| Driver | 55g | 3.8° |
| 3-Wood | 62g | 3.4° |
| Irons | 105g | 2.1° |
| Wedges | 120g | 1.8° |
