Yeah 7.9 complete as seen there, without the wheels its 5.2kg, so with some Campag Zonda's it will go down to 7.4kg, a carbon sram red chainset would take it to about 7.1kg. But just gonna upgrade wheels for now so £1100 for 7.4.

So what I bought:

Frame - ebay
Brakes - new
Front derailleur - in the spares box (needed a new bolt)
Rear derailleur - in the spares box (overhauled with new jcokey wheels and some lube and good cleaning)
Chainset - new
BB - new
pedals - from other bike
seatpost - new
seat - new
stem - new
handlebars - new
tape - new
cables - new
tyres - from old bike
wheels - lendser until I buy new uns

I've got the same frame, different setup - dura ace 7800 with a random ultegra rear deraillieur: that cost my £899 second hand. Then bought RS80s, some second hand carbon bars and seat post. THink I must have spent about £1400 on it, all in. It's about 7-7.5kg in a size L.
Can't speak for the OP's bike, but mine rides nice. Feels stiff in the corners and descents, climbs really well. A bit of flex but nothing too awful... think some of that flex might actually be in the wheels.
Wish the frame was prettier though. The logos and chunky seat stays annoy me.

yeah, but the bar tape, cables, cassette, chain and GPS mount easily offset a front derailleur.

I presume the 7.9kg is the actual weight complete as photographed, not the sum of the listed component weights?

Are all the components from bike shops/specialist online, or is some of the cost down to ebay specials, or bits lying round your shed? i.e. could someone else replicate this build for that price? Ignoring things like carbon paste and anti-seize.

All in all though , a nice build. How does it ride?

Nice work! And you've fitted two front derailleurs too - even more impressive 3
