Will Heat Or Cold Damage Graphite Shafts?

Many golfers store their golf clubs in the garage or carry their clubs in the trunks of their cars. Those environments can generate higher temperatures during summer, or expose clubs to very cold temperatures in the winter.

And some golfers believe - or wonder whether - such hot or cold environments can damage graphite golf shafts. Well, do they?

We posed the question to Tom Wishon, golf equipment designer and founder of Tom Wishon Golf Technology.

The Shafts Themselves are Fine in Hot or Cold Temps

So what do you say, Tom, will graphite shafts suffer damage or degradation if exposed to high or low temps?

"No," Wishon succinctly replied. "Never."

But the Bond Between Shaft and Clubhead Can Degrade in Heat

But that's just the shaft itself. Its integrity is not affected by the temperatures one's golf clubs will be exposed to if left in a car or the boot of a car, or an unheated or uncooled garage or outbuilding.

But that doesn't mean the club is guaranteed to escape unscathed.

"Excessive heat built up in the trunk of the car in areas where the temperatures get very hot can possibly affect the bond of the shaft to the clubhead," Wishon said.

The golf club head is glued onto the end of the shaft. And high heat can weaken that glue.

"Shafts are secured to clubheads with special high-strength epoxy glues," Wishon explained. "If the heat in the trunk of the car builds up day after day to a temperature approaching 200-degrees Fahrenheit, over time it is possible that the epoxy bond holding the shaft to the clubhead may start to break down and eventually cause the head to come flying off the shaft when a ball is struck."

Moral of the story: If you live in an area where summer temperatures are high, don't store your golf clubs in the trunk of your car long-term. Take them out and store them in your home, or in the garage where the temperature never approaches 200F.
