next gen proto frame built up

Got the frame built up and the whole bike tips the scales at 20.5lb/9.3kg!!!!!

Spec-
Severed alliance frame
Severed alliance fork
Severed alliance stem
Severed alliance cranks
Gusset open bars
FSA impact headset
Alienation Mr hand grips
Alienation post
DK pivitol seat
Alienation runaway rims
Oddy vanos hubs 12t rear
Federal 28t chain ring
Yaban Chain
KHE mac park tyres
Oddy pc pedals

Now the hubs are fairly hefty with steel bolts and there is no ti or anything on the bike, so if i change to 25/9 and used some lighter hubs i reckon i could get it under 20lb/9kg no problem.
