my ultegra set is like 6-7 years old and have never given me a hitch of trouble, so I've never felt the need to upgrade

11-speed has plenty of gear options for me. Even with more pedestrian w/kg, i rarely need my 32t, much less a 36t. And were i really in need of one, i’d do fine with a 11-speed 11/36t cassette.

That said, I am selling a 11-speed Ultegra shifting group here (just need E-tube wires), and I will soon have a set of Dura Ace 9150 Di2 FD/RD for sale as well ($475 shipped). Reasonable offers will be considered for both.

I have no immediate plans to upgrade from 11-speed Di2. I do not like the 12 speed cassette options. I race with a 12-25 cassette. The closest 12-speed ratio cassette is 11-30. That is a big downgrade.

I'm sure I'll come off as a dinosaur but I see no upside in 12 speed groupsets, only a RIDICULOUS cost whether SRAM or Shimano. They're heavier and generally have worse gearing options without getting an aftermarket cassette or chainrings especially for tri/tt. SRAM's 10t sprocket and inefficient chain (and power meter integrated into the chainring, plus limited large chainring sizes) is a complete nonstarter on any non-gravel bike for me. Shimano's only selling point on 12 speed is fewer wires, you can get 11-30 or 11-34 in 11 speed if you want and you still need aftermarket crank/rings to run more TT/tri gearing (and to have an accurate power meter).

So what exactly is the value prob for spending thousands on a road or TT bike? Granted I'm all rim brake, so the improved disc brake calipers and design on 12 speed doesn't apply to me. But still, that's a lot of cost just to improve brake rub (and again, there's aftermarket rotors and pads which help).

I have a ton of miles on both 11 and 12 speed. 12 speed is just a click better in all ways except maybe weight :) . I run 11 speed cranks on my bikes. Is upgrading worth it? Only if budget really allows. The brakes on 12 are incredible. Other than that 11 speed certainly is fantastic.
