Just acquired this awesome cheap CAAD4 Aero frame. I'm confused about the exact model and year, maybe you can help? I could've posted this on C&V, but figured it's not that old. Has anyone ridden or done any racing on these with drop bars(non TT/Tri mode)?

It has a 1" head tube(right now it's shimmed with 1 1/8 stem), from what I read online this means it might be a 2000. Some photos show bikes with similar colours but with the model name R(number) on the top tube. This has no model names whatsoever. I first thought this is a tri bike, but it does not say "Multisport" on the top tube.

If this geo chart I found is correct, then it's close to a Cervelo R5! High bottom bracket, reasonably short chainstays and wheelbase but slack front end and some trail. I want to build it with drop bars, new campy and nice wheels and ride and race the heck out of it. Stupid idea?
