Awesome! I saw that one on eBay, decided to wait and maybe go for the Alien that was up, too, then forgot about both!
I recently picked up a Nishiki Colorado. Looks very similar at first glance, BUT mine has a continuous seat tube (no lug at the TT/SS junction), and takes a 29.6 post. Has a "Made in Taiwan" sticker on it, too. I assume it's newer than yours. Cheaper 400LX Exage bits. It also alludes to Richard Cunningham design, I wonder how much input he had, or if he just one day set out a set of geometries for a size-run of bikes and they went from there.
Apologies for the blurry cell-phone pic.
legrandefromage, I recall seeing pics of yours whilst searchigna round trying to figure out how old mine is. I'm double-checking sizing, but I think a drop-bar set up is in the cards for me. Already have everything I need except the time to work on it
