This is a tidily produced document depicting an alarmingly chaotic product range. I have owned a Dahon bike (a Tournado) for many years, but I have always struggled to properly understand the complete Dahon offering. For 2011/2012 Dahon seemed to include a particularly large number of random bikes with no known reason for exisitng.

I'm must be missing, or misunderstanding, something somewhere.

When it comes to Dahon's own Neos derailleurs, the photos show a smattering of old-range SR SUNTOUR versions all mixed up with one of the new-range SunRace models (Dahon Neos 8 (RDN80)). It's a bit of a mess.
