All the literature I've seen lists two colors; orange and yellow. And, two sizes: 21" and 23". However, I've seen one World Voyageur in blue. I've wanted one of these since I discovered them, but had no reason to believe I ever would because I ride 63cm frames.
Well, two states away and 10 hours in a car and I have one. Have you ever seen a 25" World Voyageur? Just how rare is this bike?
Pics? I'll post some tomorrow morning. It goes without saying, but I'm pretty excited about my new bike.
Edit: The catalog page below does indeed list "opaque blue".
