You'd kind of have to go Sram Red mechanical, Zipp tubulars, and you'd probably be down in the 14.5 lb range. But tubulars are a pain in the ass and Di2 is so much better than Sram Red it's worth it (I ride both Di2 and Red on two different bicycles).
I never said it would be cheap. You may not like it, but buying light wheels is pretty easy. So is swapping the stem, bars, and saddle. Point is, the frame is very good for the price.
I know to take the manufacturer's weights with a grain of salt, but the complete bike is listed at 15.86 lbs. The stock wheels are 1770 grams, so there is a lot of weight to shed there. If you want to get super crazy you can shed over 650 grams (1.4lbs) with wheels alone. Getting down to 1300 is somewhat reasonable, and that's 1 pound right there.
Can't find the weights on the bars, stem, and saddle with a quick and dirty search, but I'm willing to bet there is an easy savings of 75-100 grams on the saddle alone.
It would be a lot easier with Red, but Red isn't necessary.
