Bike Identification Thread

[luckyboy]

Hey, this can be a general thread for year/model identification for parts and full bikes etc..

To start off with, I've found some early carbon Colnago bike. Am I right in thinking it's a Carbitubo? Doesn't say Carbitubo on it though, and there is no evidence of a double downtube. Maybe an early version?
It does look Ariostea-esque, and they rode Colnago when Riis was there.

Hard to tell from the few photos. If the main frame is carbon then it is an early C-40 with a steel fork. If steel it is a Master. Definitely NOT a bitubo as you speculate it would have dual down tubes
