I am getting a Dahon Cadenza. I have no idea how the forks work. But I am under the impression that the stock rigid fork won't fit a 2.3" wide tire. Any idea how to find a fork that will fit it? How does sizing work? Generally are forks one size -for the area that connects to the bike of course? I plan on putting in some Schwalbe Big Apple Tires, 26x2.35". I am not sure if the back can handle a 26x2.35", but if it is the same frame as the Dahon Jack, it should handle a 26x2.0" no problem.
