Anyone able to offer me some information on this bike? From what I understand, it's early 90s ('94?) and was only built for one year. I had help from a friend in Belgium who shipped it to me here in the US. Interestingly, it has the shaped tubing that the Colnago Masters were known for, but the (damaged) tubing sticker appears to be Tange! I'd never heard of a Tange Colnago... any information/catalog scans?
