My current folder is an R20 (Made in New Zealand). It's my first folder and I love it the way you do a first love.
Now I'm in the market for a new folder, one that folds as compactly as possible and can accompany me on my plane trips.
From my research, it looks like the Brompton takes the prize for the most compact fold. But I've also read the Brompton is fitted with "non-standard' parts. So I'm curious which of the parts on a Brompton are non-standard? For instance, is the 16" tire/wheel is of a strange size that can't be found easily?
