just regreased the bearings in my headset but I've got a small spacer leftover and I can't figure out where it goes. No, I didn't pay attention when I took the thing apart a few months ago!!! the spacer doesn't seem to fit anywhere, it's too tight to fit under the locknut. The headset seems to be working on, no play, and moves freely. Is it a big deal if I leave the spacer off?
