Check My Shaft
Know your flex, swing speed, and shaft specs before you spend money on the wrong equipment. TrackMan-powered shaft diagnostics at Swing Shack and Stick.
Why Most Golfers Buy the Wrong Shaft
// DIAGNOSTIC RESULT: WRONG SHAFT
More than 50% of golfers who come in for a fitting are still playing the wrong flex — despite having bought new clubs in the last few years. They bought based on swing speed estimates, store recommendations, or brand marketing — not actual data. The result: reduced distance, wider dispersion, and a shaft that fights their natural release instead of matching it. (Source: MyGolfSpy Equipment Labs, 2023)
What a Shaft Fitting Actually Measures
Most shaft buying is guesswork. Here's what the actual measurement process looks like — and why it matters.
We use TrackMan to measure your transition timing, release angle, and actual shaft loading pattern. This tells us not just your swing speed — but how that speed interacts with different shaft stiffness profiles. The result is a specific flex, weight, and torque recommendation based on your biomechanics, not a sales rep's intuition.

Core Diagnostics
Shaft Flex
The most misunderstood variable in golf equipment. Flex isn't just about swing speed — it's about when you release the club relative to impact. Same speed, different release = different optimal flex. We measure your transition to determine the exact flex for your release pattern.
Test Your Flex →Swing Speed
Clubhead speed determines which shaft weight and flex you can efficiently handle. We measure your speed across the full bag — driver through iron — because your iron speeds and driver speeds often differ more than you think.
Measure Your Speed →Shaft Weight
Lighter isn't automatically better. We test across a 40g weight range to find where your strike quality and consistency are optimized. The right weight is where your TrackMan numbers improve, not where the club feels lightest.
Weight vs Performance →Shaft Materials
Graphite vs steel has a real performance implication — but not the one most marketing suggests. We explain what material actually changes for your game, and which situation calls for which.
Graphite vs Steel →"I was playing stiff flex because I thought I hit it hard. TrackMan showed my transition timing was late enough that I needed regular flex — and I'd been leaving 11 yards on the table because of it."
