Reading a Shaft Spec Sheet Correctly
Flex, weight, torque, and trim all shape how a shaft actually performs — and none of them tell the full story alone. Here's what the numbers mean once a shaft is on our bench.
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 during the downswing relative to your own 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 it at all.
Steel vs. Graphite vs. Multi-Material
Steel
Heavier and more consistent shaft-to-shaft, offering precise feedback and control. Still the standard choice for iron and wedge shafts among players who prioritize feel.
Graphite
Lighter weight raises swing speed for players who benefit from it, and dampens vibration for a softer feel. Standard in drivers, fairway woods, and hybrids.
Multi-Material
Blends a steel tip section with a graphite body to combine feel and consistency with reduced weight and vibration — a growing category in iron shafts.
What Happens Before a Shaft Ever Meets a Head
Every raw shaft blank is cut to a working length, then trimmed from the tip or butt end depending on the target flex and swing weight — tip trimming stiffens a shaft and lowers launch and spin, while butt trimming adjusts overall length and weight with less effect on flex feel.
Torque measures how much a shaft twists under load. Lower torque generally means a more stable feel for faster, aggressive swings, while higher torque can add feel and a softer release for smoother tempos. We check torque and trim together, since changing one shifts how the other behaves.
Find Your Shaft Match
We test flex, weight, and material combinations against your own launch monitor data, then trim and build the shaft on our bench.
