My 1978 Raleigh Competition G.S. is 23.5 lbs (≈10.7 kg). The 2020 Tarmac Disc Comp Ultegra Di2 is 17.5 (≈7.9 kg) both with a small seat bag with tube, inflator, CO2 and some misc hex keys. No bottles. IIRC and probably weight accuracy is plus or minus ½ lb. I don't really obsess over knowing weight to the tiniest gram. It's just for rough comparison.
Will that do?
