Been riding the **** out of my bike now that I finally got the frame back from the powder-coaters, it's been lovely weather. Pictures to come soon! 24 miles a day, 12 each way for the last week, it's been a while since I've gotten that much riding in, loving every second of it


But...

The lockring and cup have been coming loose on my headset about every ten miles or so. I don't mind reaching down and tightening it for a temporary fix, but it's not ideal. If memory serves me, I think this started happening after a couple of my friends came back to my house after a ride and said "so we've determined that your bike is not possible to bunnyhop with." They are good friends, so I didn't think too much of it, but needless to say they won't be riding my bike without supervision anymore.

Anyway... I was hoping for some advice as to a fix for this problem. I was contemplating some "Locktite" on the threads of the cup, to see if that would help - as I have adjusted it the correct way numerous times now.
Second solution would to be to purchase a new headset, which I also would mind, as my birfday is on the 8th and I should be getting bicycle giftcards

The only other thing I could possibly (but grit my teeth doing) imagine is that the punishment the neck of the bike received during this fiasco led to a bent frame. In which case...



Help? Advice? Ideas?
Thanks!

Is this a threaded headset ? Are you talking about the locknut and top adjustable threaded cup ? Are you sure the locknut is not bottoming on the threaded steerer ? More details and photos might help diagnose the problem.

My vote is for improper adjustment. Make sure the locknut is tightened against the upper cup. This means you need 2 wrenches on it, not one. See Park Tool's how-to.
