Guys, for give me for not knowing about this stuff. I tried suggested way of loosening the stem bolts and then just nipping the cap bolt, but it's still loose. I then took averything apart, being carefull to note what went where, cleaned it all off, regreased and put everything back. Just as it came off, but it's still got the play in it. It's still the old style ball bearings, if that helps.

Can anybody possibly offer me some advise please.

Add another 5mm spacer under the topcap - sounds like it's bottoming out on the steerer instead of preloading the bearing.

While I was driving home I had that same thought, do spacers all have the same internal diameter? Or is it fork dependant. The fork I have on the bike is a Suntour XCT V4, if this helps any.

I dont think the spacers ID has to necessarily fit flush with the OD of the fork steerer... but enough that the top cap has ample fitting surface to tighten onto..

28.5mm is the diameter of the steerer and I'll get a space or 2 tomorrow @ Neils Wheels in Plum. I now have another problem. The shaft going down into the steerer has a long bolt joining the 2 pieces together, cut at an angle, should this be tightened into the shaft or must it be loose? Cause when I tighten it, it just works itself loose after a while.

 

Please help, breaks my heart to see this bike standing here with problems. Kinda like the Land Rover I had, damn thing drove me :wacko:

Are you talking of this kind of stem? If so, bolt should be tight

Ah. Sounds like you've got a threaded headset - the spacers won't work on this one. You've just got to set the bearing properly. I'd suggest a visit to Epic in Plumstead, they'll sort you out.
