Very nice input guys! I'm hoping to source as much as I can. Brompton parts are what I wuld like to mostly achieve, but I know there's a big majority of Dahon riders out there. That's why I chose those 2 brands.

I'm working on the Sram A2 hub. I called the headquarters in Chicago and they didn't even have 28h on their list. So, I must be a German/European special hub. Found a few, but for a hefty shipping fee.
