Here's my information:

1. It's a 12 speed, Shimano components, shifters on the stem for the handlebars
2. The frame says: Tange 900 CR-MO Double Butted Tubes
3. The fork says: Mangaloy 2001 Manganese Alloy Tubing Tange
4. The frame also says "Made In Japan."
5. The serial number on the frame is: KS544851

It's kind of a blue-ish color. Any ideas what year or model??
