I'm new to foldies and just received a Downtube Mini. I ordered the 2009. I expected the stem to fold between the halves of the bike. Instead it folds to the outside, so the handlebars kind of stick out when folded. I'd appreciate it if anyone else has a 2009 and can shed some light on this. How can I tell whether I got the 2009 or the older version by mistake?
