Loose Threaded Headset(4 posts)

I have a '00 GT ZR 4.0 with an aluminum fork and threaded headset that keeps coming loose. I've taken it to my LBS to have it adjusted 3x in the last two months and it's loose again today. I ride a fair amount (~100 mi/wk) on average roads.

Is this normal? Would an upgrade to a carbon fork and threadless headset help the situation?

Thanks for the advice.

Why does it come loose?Kerry

Is it possible your head tube is not square? Are the threads partially stripped on the existing head set or steerer tube (is it an Al steerer tube as well as Al fork?)? Is your LBS maybe not all that skilled? Until you know why things are coming loose, getting a new fork seems an expensive experiment. Absent some sort of other problem, a properly adjusted and tightened HS does NOT "just come loose."
I'm with Kerry--I'll bet it's bad wrenchingcory

I've had threaded headsets for close to 30 years, and the only one that's ever come loose is one I tried to tighten with pliers because I didn't have the right wrench. If it's properly tightened (hold the lower nut and run the upper one down on it pretty hard) it should never loosen.
Grant Petersen at Rivendell says to use beeswax on the threads when you cinch it down. I do that because I have some beeswax, but even before I got it, they didn't come loose.
