Bing! This is a light bike and rode well in short loop in the parking lot. It may be a keeper.

1985 Centurion Elite RS
The first letter of the serial appears to be a N (or is that a W). Several photos from different angles to get the light in there. I included the one that looks most like a N.
N5M5555 or W5M5555

Shimano Crank date code 1985 May
Biopace rings
Shimano 600 derailleurs
Shimano 600 aero pedals (horrid pedals. Grease has them nearly seized up.). does any one use toe clips anymore?
Suzue hubs
Araya 700c rims
Suede saddle.

Needs a full overhaul, tires, cables, pads, etc.

I noticed they put a black waterbottle cage on the black downtube and a silver cage on the silver seat tube. Cute.
