Point being, It can be done for way less than $1600.
Yes, you are correct and I should have been clearer that my $1600 quote was the whole system - shifters, both derailers, crank, b-bracket, cassette, chain, brakes, charger, junctions and cables and a WiFi unit. Texas Cyclesport (USA obviously) was the cheapest I found for the basic 8050 upgrade - shifters, derailers, junctions and cables, charger and WiFi and ran slightly over $1000. Interestingly enough, the 6870 basic upgrades I’ve seen are only about $100 cheaper.
