I just received a 2005 Downtube VIII that I bought on eBay. Anyone know where I can locate a list of Downtube retailers in my area? I think I need a little tutorial on adjustments and folding the thing up. I've never owned a bike I needed to adjust or fold and the directions aren't idiot proof. Anyone else have this problem?? Specifically, I can't get the mid bar or handlebar stem joints to fold.
