I bought a Centurion bike from a friend last fall, and have recently been trying to figure out its history.
I read Ashley Wright's article (posted on sheldonbrown.com) about Centurion:
Ashley says the company stopped making the Centurion mark in 1990. I'm guessing that my frame is one of the last that was made, since it has a more modern seatstay setup (see pics at link below), and vertical dropouts.
I have posted detail pics at:
Does anyone have more info/ideas on this frame? Thanks!
