From what I can tell, the SRM is only adding ~80 grams over the stock S-Works spider. Well worth it IMO.
Here is a good baseline I was using to predict my final build weight:

I should be a little less with the RED 22 rather than Dura-Ace. I should also be a little lighter with my wheelset.
They are claiming 13.7 pounds?!

Standard SRM adds about 100g: Compact Quarq was about 90. Standard tubes are 100g ea. Lightweight tubes (conti supersonic or latex) can get you down to 50 for 100g savings. You can lose quite a bit on a lightweight cables: iLinks or the like will save 50+ grams.
Sram red Brakes are relatively porky: eecycleworks or planet-x will save a good chunk of weight (60g per)...eecycleworks are $$$ though.
Weigh your bottle cages. You can get 18-20g carbon china clones pretty commonly from ebay. I'd wager there's the opportunity for 50g savings there. Perhaps more if your bolts aren't aluminum, but I think the s-works comes with aluminum bottle cage bolts.
So:
tubes: 100g ($25)
Brakes: 120g ($120) planet-x
Cables: 50g ($100) (could go ti cables or powercordz for more)
Cages: 50g ($40) china clones
~320g for less than $1/gram.
Could also look at the weight of your bartape - it looks thick/heavy. Chainrings might be a place too. Sram rings are heavy. Can't tell which rings you are running though.

I will never understand the sense of carbon-clinchers.
Well I do have 202 firecrest disc wheels on my Defy but I agree. Coulda built a lighter wheel for 1/3 the price.

My 58 pro disk R785/Ui2 is 1200g heavier with stock everything + quarq, praxis rings, k edge mount, Dave-o cages and speedplays. Doesnt seem so heavy now lol

Both of my '15 SW Tarmacs weigh between ~14.5-15lbs, depending on what wheels I have on at the moment. That's with everything, including head unit mount.
Both are posted in the intro forum, one with 11spd Red and one with SR EPS, both with Quarq's. So, sounds about right to me.
Have you ridden it yet? I forgot about weight all together after I rode mine. Best bikes I've ever ridden.

This is great feedback. Love these simple options to get me closer to where I want to be.
I'm on the S-Works chainrings. I'll have to look into weight on these.

Comparing apples to oranges will only result in heightening ur weightweenie grief.
Here is a good apples to apples comparison for your bike.
viewtopic.php?f=10&t=129270 ...tubulars and no powermeter make up the largest difference

the tarmac frame is NOT light.
it does well in stiffness/weight ratios because it's obscenely stiff, not obscenely light..
as above, cockpit - bar/stem/post can be lighter...
tubulars, obviously will drop you at least 200g in wheels alone
titanium spindles, skewers, etc. - but without tubulars no way you're going to touch 14lb with that.

All except the last picture with the bike on the scale showing 6.13 kg. That's the only picture without pedals and cages......so its heavier and quite comparable to the OP's build.
Huh? We are making the same point. If the bike in the website posted above was weighed complete with pedals and cages, it would weigh closer to the OP's bike ( approx 350 grams) . However the bike in website still has the weight advantage with no SRM (approx 80-90 gms) and tubular wheels/tires (approx 250-300 gms)
