Duh.

It's pretty amazing how well a lot of the 1980s (or a lot earlier)
stuff still works if it's maintained reasnonably well rather than
abused. I have a bicycle with the old Shimano 600 EX stuff on it
including the scallop headset and I never have problems with it.


And if that choice words deleted scalloped headset shakes loose all
the time there is a solution which works to this day on my road bike:

I have NEVER needed to resort to the use of a hoseclamp on any headset on any of my bicycles.


You probably only ride on fairly smooth asphalt. I have a share of dirt
and other rough turf during most of my rides. The countering action of
the top nut just ain't sufficient for that no matter how hard it is torqued.

A small drop of LocTite will solve that and it won't cut your finger
like a hoser clamp.


At some point in time either you or a shop did something that knackered your top nut on your 600EX headset.


I am not the only one who has that problem. Except the others eventually
didn't have the bikes anymore, which "fixed" it for them. I keep
technical things for a long time.

Anyhow, the hose clamp fixes it for me. When I get around to it I'll put
in a new non-600 headset.


I wonder if someone over tightened Joerg's 600EX headset top nut and stripped it? Or if he has the right top nut on it? ANyhow, lots of them were sold and lots of them were used without Joerg's problem showing up. Joerg seems to think that he's the ONLY ONE who rides a road bike on trails.

Actually I have had the same problem that Joerg has. Adjust and
tighten the steering bearings and in a few days the bearings would be
loose.

A little investigation showed that the top nut instead of bottoming
out on the upper bearing race and locking it, it was bottoming out on
a very slightly too long steerer tube. I added a washer, perhaps 3/32"
thick so the top nut actually tightened against the bearing race and
have had no more problems in the last couple of years :-)

Which confirms my statement that the headset locknut was not installed correctly.
