This bicycle was only imported to the US by Panasonic in the last year that they sold bicycles here. After 1989 the currency exchange rate made the bicycles uncompetitive and most bicycle manufacturing shifted to Taiwan. This aluminum frame was assembled in a manner similar to Vitus, Alan and Raleigh. Aluminum tubes the same diameter as a normal steel tube were bonded into an aluminum lug with an adhesive. There is a nice drawing on the last page of the 1989 Panasonic catalog (Google 1989 Panasonic Catalog) that shows the process. There are a few scratches on the left downtube near the Panasonic decal and a paint chip on the left side of the top tube, other than that it is a very good looking, light weight road bike. I don’t know the claimed weight but it feels very similar to a Vitus 979 and I would keep this if it was my size.
