As well as the Potenza group being MUCH cheaper than the Record group, it is much more reliable aluminum construction and is the only Campy group available with a triple and/or a rear derailleur capable of accepting a 32 tooth cassette.

While Shimano has engineering professionalism, Campy is artistic to a fault. Yesterday I used my Colnago which has Di2 and it started skipping gears. Now this might have been because I have a 10 speed crank but I doubt that. I realigned the rear derailleur after I got home and it appears to work fine though I will have to take it for a hard ride to tell. Also - When I installed the Di2 I ran the wire from the opening on the left side of the top tube, over and down the downtube as the diagrams for Di2 suggested. I believe that the better choice would have been to run it back to the seat tube and down to the derailleur splitter.

Now we do not know for certain but it appears that the 2021 Di2 is going to be wireless since they are losing a great deal of business to SRAM since it is so much simpler to install.

Potenza is discontinued; use current Centaur[1]
There are no triples.
All the Campagnolo road series have a 32t low gear option.

For some clever Italian engineering, how about a sprocket
stiffener on the low gear which obviates a chain between low
gear and spokes?

Some of us have waited for that all our lives.

[1] same except the new CEN crank is slightly heavier.

Well I see that the 2021 Record 12 speed manual groups now support 11-34 cassettes, but the 2020 rear derailleur I had would not. I was under the impression that the only arm length of a Record was short and medium and both would drag against anything larger than a 29 tooth cassette sprocket. My friend who was going to buy a Record group for his New custom Tommassini bought a Potenza group instead because he could not get a sufficient gear ratio for him and his wife to climb those terrible hills around Phoenix. (I can't climb very fast anymore but riding with that group made me feel like I was 21 on the rare climbs of more than 3%.)
