Hello...this is my first post! I'm just getting into cycling, and am looking for my first road bike. There seems to be a pretty good deal on a Peugeot Monaco (I believe Canadian made/ProCycle) in my area, but I can't figure out the date of manufacture. The serial number is Y711 24906. I curious as to the date, because I'm looking for a bike to train on for next year's Eroica, and the bike has to be pre-1987. Any thoughts (she's white with blue gold and red decals)? Is this a less-than-ideal first bike to train with/rely on? Thanks--love the information and enthusiasm here!
