hmm,
I've never quite understood the Centurion love, hardly classic, or vintage.
To me, Centurion is just another of a long line of marketing companies. They did not make a single bike, but they did a nice job of choosing others to build bikes from them. The 1970s and 1980s was full of such brands: Centurion, Univega, Nishiki, Lotus, etc. I have had nice bikes from all of them, currently have a Centurion, Lotus, and Univega in the "collection". Oh yeah, and my favorite Schwinns were all made by Panasonic.
I really like the 1970s Centurions.
Robbie, that eighth version is a true classic...
