The frameset-versus-complete question has a spreadsheet answer, and it starts with an uncomfortable fact: a factory complete is priced like a group buy, and your parts drawer is not.
When the complete wins
Starting from zero, the complete bike wins by 15–25% — the factory pays wholesale for the groupset and so do you, indirectly. If the spec sheet already matches how you ride, take the discount and go train.
When the frameset wins
You already own a groupset you like, or you're specific about contact points and wheels. A frameset build reuses the expensive parts and spends where your body notices — and unlike the complete, nothing lands in the sell-off pile.
The hidden column
Add build labor and small parts to the frameset column honestly: headset spacers, rotors, cables, bar tape — the drawer is never as full as remembered. If the totals land within 10%, choose the build; bikes you specified get ridden more. The same platform, three ways to buy it: the T1600 Ultra Frameset, the T1600 Ultra · Ultegra Di2, and the T1600 Ultra · Dura-Ace Di2.
