Cannondale serial numbers- older bike
 

I'm a newbie to road bikes and recently was given an old Cannondale road bike with the serial numbers 65409890003 stampted on the bottom of the rear stay. At the end of the stay is stamped NG and the letters PS are circled. The decals only say Cannondale Handmade in America. The bike is brushed aluminum and unpainted. Someone mentioned it may be a triathlon bike. Can anyone tell the model or size of this bike or anything about before I start putting money and effort into it...

Thank you...Imalpo

Thanks, that would at least define the size and year. If anyones knows how to find the model, that would be great...Thanks

So, lesseee. I'm drunk so this will be surprising if I get it right.

6=126mm rear dropout spacing
54=54cm frame (not sure which tube it is. I'm prety sure it's the seat tube.)
0989=built Sept. '89
0003=third bike made that month.
Is there a way to find out the model from that?

Look here is the 89' catalog (pdf file) find your bike in it.

So that looks to me like it's their Criterium model! It doesn't say any of the bikes come in brushed aluminum, but I've seen colors that weren't listed in their catalogues, so I don't know if that means anything. It could have been refinished.

It's obviously a piece of crap. Here, let me take it off your hands.
