Another photo of my new old International. I've been trying to confirm what tubing this frame was made of. The attached photo shows the frame sticker (Double butted Cro-mo) but does not name which Tange grade it was. I've heard all sorts of opinions on what KB used in 1980.

I was able to weigh the bare frame (just with the fork/headset and the right BB cup and it weighs the same as my bare Raleigh Professional (1976 531 tubing) - well as close as the bathroom scale can tell. That implies to me my international could be Tange #1 or #2 .



Like the Raleigh Pro the frame rings like a bell when you plunk it with a screwdriver blade or a wooden dowel. They sound the same (and sound great). In fact, fully assembled, this International weigh the same as my aluminum/carbon 2000 Cannondale R600. SWEET.

Does anyone (T-Mar??) actually know what tubing was used on the USA International for 1980? Thanks.
