After my first ride on my new bike I noticed a wobble in the headset/stem area. It is a Colnago threadless headset with a Colnago ITM stem and 2 spacers between the stem and the headset onto a Flash fork. The stem does not fit flush onto the headset and the "sleeve" inside the stem bracket that slides onto the fork tube actually is shaped with an angle on it. Now I have this wobble and nothing fits perfectly flush! The LBS tried to adjust this problem but after really cranking the center bolt tight, then the steering was too tight. So I tried to loosen it off so that the steering isn't so stiff and now the wobble is back. I am really miffed and I feel I am becoming a pain to the shop. But I don't think the entire steering mechanism should wobble??? Sorry for the long post but any advice or opinions would be appreciated.
Joel, you had better fix this. It's potentially dangerous and can damage your headset.
First, you need a better shop, one that knows how to do basic service.
Better yet, learn how to do it yourself. There is good info at Sheldon Brown's website.
The center bolt adjusts the headset bearings, and the adjustment is held by tightening the stem's pinchbolts so that it cannot move on the steerer tube.
