I've done a couple of searches and found conflicting answers about the effectiveness of expander nuts in an aluminum steerer tube.

However, my situation is a bit different since I already have both a star nut and expander nut available to me.

My Cane Creek Forty headset came with a traditional star nut and my Forte carbon fork (with aluminum steerer) came with an expander nut.

I'd rather use the expander nut since it would save me the 10 or so dollars it costs for a star nut setter, but I'm afraid that I may run into issues if it doesn't work.

Basically, what I'm asking is, is there any harm in me trying the expander nut first? Can it be easily removed and replaced with the star nut?

Thanks!
