Dahon Neos 2.0

Dahon Neos 2 derailleur main image

Dahon salespeople like to claim that the Dahon Neos 2.0 is a ground-breaking step up from the genuinely revolutionary (in its time) Dahon Neos. I haven’t been over it with a micrometer, but it seems to me that the differences are small - you get an Allen key cable clamp bolt, a nicer adjustable cable outer stop, a slightly redesigned top knuckle and a gratuitous black piece that makes the visible parallelogram plate look prettier (or black).

Dahon do now claim that the Neos 2.0 can handle a 32 tooth cog, and that it is 8 speed compatible - so maybe they have tweaked the dimensions - or maybe not.
