I like 50-24-34.
I prefer 50-34 in flats and on hills. I use an 11-25 cassette. I am comfortable with my cadence at 95-100
I have three bikes with cables, one bike with electric shifting. All I can say is that I spend much less time putting the battery on charge every month or two than I spend replacing cables every six months or so.
Been riding compact(50/34) for about 5 years now and LOVE it. It's the perfect mix of gearing. That said, I'm getting another set of rings for a sub-compact(52/36) which will be better for the terrain I'm in now.
I run an 11-28 cassette...I love the setup.

Drew...I feel ya on the triple bro. I owned a Campy triple a few years back and loved it. Tight spacing...lived on the middle ring mostly and rode it like a 52/42 but when I needed the short gear inches, they were there. I believe this explains the love hate relationship with a compact and why it took so long for compacts to eclipse triple cranks in sales....in spite of reduced complexity aka 2 versus 3 chain rings and weight reduction...gear spacing just isn't as friendly with a compact.
So what will I do moving forward? Based upon all the great input from this thread and the relatively foul taste of riding my unmodified 50/34 Campy compact before I changed the inner ring to 38t...I will change the cassette instead. In fact, this seems to follow the trend that Sram and Shimano and now Campy is following suit with...spawned I believe from the mtb crowd which are also evolving to 2 versus 3 chainring cranks. The trend is toward bigger cassettes. In context of Campy which has offered a 13-29 10s cassette for years, that will be my next cassette I will move to without changing the 50/38 because I don't want to give up the nice tight front spacing if I don't have to. Doing some quick math, a 38t front ring with 29 tooth rear cog is the equivalent of a 32-33t front ring with 25t biggest cog in back. This will do for my riding with modest hill grades even after my legs are toasted. As to all the guys here that can't live with 50-13 for descending, I'm with you Drew....I can too and you rode one in the Rockies for a decade. Without racing and need for powering down the hills since I don't like to descend too fast anyway for safely, a 50-13 at high cadence will be fine. Further, a bigger lower cog keeps a 13-29 cassette more tightly spaced which is reported to work fine with short cage Campy rear derailleur even with wide spacing of full 50/34 compact. It will work even better with 50/38 because chain length difference won't be as extreme small-small to big-big. Campy also now sells 12-30 I believe in response to Sram and Shimano offerings, but have to believe a medium cage derailleur would be required to handle the chain length difference of a 12-30 between gearing extremes.
Thanks again everybody.

Never snapped a cable, but I carry one each with me. With electronic shifting, there is no way I know of to to carry spare unicorn horn powder
The love for 52/36 is interesting; my goal for next year is to get my FTP from 251 -> 265 so my small ring can jump to 38t, which would mean I can move up to a 130bcd and 52/38. I wouldn't want a 16t jump again.
Good thread. I'm impressed that no love has been shown for cross gearing. One of my favorites bikes has a 48-38 with a 12-27 on the rear. I like that you can spin on both the 48 or 38 and the 38 running on a 27 gives you a very good low gear. I used this combo a lot in a really hilly area.
I have a 50-34 crank sitting in a box that I plan on using fora new build. I'll give it a try but I suspect I'll swap out the inner for a 38 before too long. I don't live somewhere too hilly now so I know the drop down to 34 will drive me crazy sooner or later,
There is some love for 46/36 in here somewhere, but damned if I'm going to go through the whole thing looking for it.
Drew brings up something I've considered for my 9 speeds - the 14-23 cassette with a triple. It makes the 30t more relevant up front, but takes out the benefit of the 52t on descents.
The answer at which I always arrive is to HTFU.
Or, as I put it here, charge the Di2 battery when you charge your Garmin.
The 34 is kinda questionable, I only use it when the hill is super steep or its a sustained climb. I basically use the bottom 3-4 gears(28,25,23, 21) in the 34 and it works out just fine. In 34-28 @ 50rpm its like 4mph, so if you're going slower than that, yeah gearing wont help you much, you're just standing on the pedals mashing anyways.
I like the 28 for rides when I don't want to hammer on a climb, the 34-28 gives me that option, I can casually coast up the hills.
I got 52/36 rings coming in this week, and I'll probably install them in a week or so. I'll let you guys know how it goes. I played around with the online calc and it isn't MUCH different. I personally don't care about going downhill faster, but i'd like to have a little more top end for crits.
