This, German language, Dahon catalogue is for model year 2014.
I think it is the last catalogue that featured all three of the second generation Dahon Neos models that were manufactured by SunRace (Dahon Neos 7 (RDN71), Dahon Neos 8 (RDN80), Dahon Neos 9 (RDN90?)). 2014 seems to be the last model year that Dahon remained commited to its signature derailleur design.
As usual with Dahon catalogues, there are plenty of odd inconsistencies between the images and the listed specifications. It's surprising how many companies run by scientist/engineers have a weird lack of attention to detail in their customer communications.
