Headtube or headset sticking ?

Ack !, I should add I've tightened the bolt that goes into the star nut so
much the seal on the headset is bent out of shape. Headset still moves under
stress.

If you've tightened it that much, you may well have damaged the bearings
and / or the cups. If this is the case, it could well account for
movement.

The steerer has about 1-2 mm clearance at the top and the top cap isn't
rubbing on it as far as I can tell.

The stem should sit proud from the steerer tube, not the other way round:

All in all, it sounds like a bit of a mess. Might be time to take it to
the LBS.

It's time for the LBS mechanic to take a look that's for sure.

Thanks for the help Bomba.

Keep on rollin' !

It's the top part of the aheadset that's slipping, the cup that attaches
to
the headtube. It's moving about 1/2 a mm or so. Can that be tightened if
the
headtube is still square ?

The headset is all one unit. You tighten the whole thing rather than just
the top or bottom sections. There should be no back and forth movement in
the headset at all, and should be easy to tighten.

Thankfully it's not an integrated headset. I'd be royally ****ed off if it
was !

You probably need a new headset, a stock headset only lasts me about 6
months, get a new one in the $30-$50 range and it will last a lot
longer. If it's only of those garbage integrated headsets well you
might be screwed.

I've now learnt how to pull apart a threadless headset, and I've sorted out
the problem. It turned out that the bearing cup had been packed full of mud
etc and a little rust. There was bugger all else the headset could do under
pressure, but stick.

Now that it's all greased up and cleaned there's no stickiness.

Should have learnt how to do it 2 years ago when I originally got stuck.

Oh well.
