Headset bearings.

I'd ceretainly be striping it and cleaning it - when you get the thing to pieces then you can judge if it needs new bearings and what kind they are. If it is notchy then that's not right and it needs attending to or it will wear the bearing seats

I think I could feel one set a bit sticky, so just replaced both, so thanks for the tip. I'm now a bit concerned when I stuck it back together, there seems to be quite a gap in the top bearing. Everything is tight, although not torqued, and there's no movement. Is this something to be concerned about?

Check that you have fitted an identical size bearing and that everyhting is in the right order

The guy in LBS put my bearings on a micrometer so I'm fairly certain that they are the same size, 42 mm I think he said. Not much to check on the right order but I'll have another look tomorrow. Cheers.

42mm is way out 4.2 maybe

I'm guessing he means the diameter of the race or caged set of balls not individual ones.

Sorry to be so vague, but that's exactly what I meant. Complete sealed unit.
