I've finally been working to get this apart. I had to move both home and office the past months so didn't have time. I'm a bit stuck on getting the stem out on this bike I've got the bolt loose at top of stem - I'm assuming this is a type with an expanding wedge. I've given the stem and the bolt a tap or two with a rubber mallet. Still won't come loose. Since this is an old bike maybe I'm not doing things right. Any ideas? Also, the headset - does it appear that it takes a special wrench? Should I post this somewhere else on the forum?
