This is my first build, so maybe this is not realistic (the weights are just circa):

Frame (incl. fork and fittings): Principia Revolution 1700 gr.
Gruppo: Dura Ace 10-spd 2200 gr.
Pedals: Look Keo 250 gr.
Handlebar: WCS 240 gr.
Stem: WCS 120 gr.
Saddleposts: Principia 200 gr.
Wheels: Dura Ace 1700 gr. (incl QR)
Tires: Continental GP4000 400 gr.
Saddle: SLR 150 gr.
Bottlecages: Don't know 60 gr.
"The rest": 500 gr.
That will be 7520 gr. for a size 61 alu frame. Is this serious or did I miss anything?

Thanks!
