Apparently, the Dahon Speed TT has ben replaced by the
Vector X27H.
Thanks much for the feedback about Brommie vs. Dahon/Tern.
I don't use a folder to commute but rather for touring + train trips (and possibly plane trips, but I haven't tried yet), so folding isn't a big issue since Dahon/Tern fold small enough to fit.
For that purpose, I'd rather get a folder with 20" wheels and more standard parts, so it'll probably be a Dahon/Tern (or maybe an OriBikes, although they're hard to get in Europe.) Since I'll be upgrading from a Birdy World Speed and its 56T chainring + 8 speeds, I'm looking for something with more gears (2x10 sounds good) that I can ride for about 100km per day without hurting too much, all road.
Those look good:
Thank you.
