Yes, Tange Champion #2 is a very nice tubeset, generally used on very nice bikes, at least the ones that had a full Champion #2 tubeset and not a mix. And during roughly the first half of the '80's, when touring bikes were at the height of their popularity and the bike companies were clamoring for a share of the touring market, top-line, no-compromise touring bikes often came with high end tubing. I've got an '83 Centurion Pro Tour that's got Tange Champion #2 (including the fork), Trek had their infamous model 720 with Reynolds 531, and the list goes on and on. What's funny is that Tange Champion #1 and Champion #2 (Champion #1 was an ever so slightly lighter tubeset than Champion #2) had recommended maximum rider weight limits, they were race oriented. Being a slightly lighter tubeset, the Tange Champion #1 had a lower max. rider weight limit than Tange Champion #2. Tange Prestige was lighter still (150 lb. max. recommended rider weight limit). BUT, they were making bikes intended for fully loaded touring with Tange Champion #2! It's hard to figure that one, but apparently there was enough confidence in the tubing to do such a thing, and as it turns out, the Centurion Pro Tour, for example, has earned an excellent reputation as a utilitarian bike over the years. I like to call the early to mid '80's "The Golden Age of the Touring Bike"-

FWIW, here's an '84 Centurion Pro Tour with Tange Champion #2 from a catalog page on Sheldon's site: http://sheldonbrown.com/centurion198...0pro-tour.html
