My carbon Athena groupset is 4.79lb vs. 105 5800 at 5.5 (-322g)
My Argent wheelset is 1372g vs. 1746g (-374g)
My FSA SLK carbon post is 222g vs. 246g (-24g)
My Pro One 23c tires are 235g ea., plus 20oz sealant ea, so call it 500g vs. 557g (-57g)
My 3T Ergonova Pro 44cm bars are 272gm vs. 299g (-27g)
My SMP Dynamic is 265g vs. 249g (+16g)
My pedals Mavic SL Ti 226g vs 249g (-23g)

I also have 78gm worth of Lizardskins DSP 3.2 tape on there and a light KMC X11 SL chain at something less than 243gm (since I took out a few links). I've weighed the stock 100mm stem (with Ti bolts) at 115gm.

Now, I've never weighed my frameset, but looking at those numbers, mine should be in the area of 811g lighter, or 1.78lbs (if they're the same 54 ST size frame).

I suppose it could be that mine is MY'12, but we don't have any reason to think the frame is different in any way other than paint scheme, so either INPD's frame is smaller, or one of our scales are off (though I used published weights for everything except the total bike weight and stem). Bicycle Times mag weighed a MY'12 in the 54 ST size with Ultegra 6700 (5.15lbs, and lighter than 105 5800) at 20.05lbs, which lines up much better with my bike weight given the lighter components.
