Oakleaf,

Thanks a lot for your response. I've been searching online for a good picture of my bike and don't see it. when I bought the bike they told me it was a comfort road bike, I think it might have a set up like the cypress giant bike. I wonder if that's the way the bike came or if that was an option...anyway, I can adjust the handlebars/stem so I can sit up fairly straight on this bike if I want to.

I'm sure it's threaded. But when I loosened the top bolt nothing would move. I tried loosening the lock nut but that didn't work either. But maybe it's stuck..
