My new used Ridley Helium

[roca rule]

I want to do put lizard skins dual white and black, but what do the weenies think? I think sub 15lbs should still be possible with force and sram force with an s900 crank. The build list includes
Sram s900
Sram force shifters
Force derailleurs
Look keo 2 max carbon
Planet x brakes
3T cockpit
Fsa rings (praxis when 52/36becomes available)
prologo choice saddle (until arione snake becomes available in white)
Lizard's skin black and white tape
1100 gram wheels from my look 595
Sub 15 sound reasonable right?
