I'm kinda wondering what this particular bike looks like after about eight years since the OP. Whoever used to ride it must have had a long torso with that big long stem on that thing. And, Tange Prestige is a Unicorn brand type of tubing. (I've never actually seen one myself). In fine condition, the bare frame is probably worth about $300. (Complete bike well over $600). This bike represents a big turning point in steel bike history. It's when the Japanese finally conquered the industry and took control of the international bike market. (Bye bye Italy . England . France . USA. ). That's it. That's all. Done deal. Be good. Have fun.
