Excuse me but I am a little pissed off at Dahon at the moment. I spend a bunch of money on one of their bikes and not even one month later it's at the bike shop and I have no idea when I get it back. First bike in my life that failed me. Maybe my bike has a different mechanism because it's quite easy to see the parts in question if you fold the handlestem. If I were about to buy a Dahon I would send them an email to see if you even get a response. I have sent three and have received not one response.
