Why 50-34 sucks for commuting

Not sure why I have never cared or noticed much about gearings. 10000s of commuting miles in the last few years on multiple bikes and could not tell you what any of the gearings are other than a double or triple crank mated to 5,6,7 speed freewheels. Need to climb? Downshift, need to pick up the pace, upshift. Only real thing I aim for is keep chainline as straight as possible

On my mountain bike, I converted it to a double by removing the big ring. The shifting improved dramatically and 42x11 is too tall a gear for rough trail riding (at least at the non-pro level).

I think such an absolute statement (as in this posting title) is not very helpful.
Not all commutes are created equal. Distance, weather and terrain are important characteristics of any commute, and these characteristics vary widely.
I commute on a 50-34 and I think it is just fine.

I think it just depends on terrain like hub spinner said. I have always had a mountain bike triple so the bike i have now, 50 34t compact is a first. It took me a while to get used to the jump between 34 and 50, it certainly is large. But i studied the gear ratios (stock cassette is a 12-30, but I'd prefer something like 12-27 or 28) and i shift small ring, and gears 30-15 then I have met a gear that my 50 ring matches. So i upshift to the 50 and down shift back a few gears and I am right at a similar gear ratio and moving up the 50.
I think it goes without saying that my 2x10 obviously doesn't cover the gaps like a 3x10 or 3x11 would, but the 2x10 is sufficient for my needs. The biggest concern I have is trying to avoid adverse chain angles. I am contemplating switching down to a 44 or 46 large ring but I just love getting in my powerful gears going down hill.

I don't know if you guys realized this, but it is possible to turn the pedals at different cadences.

Depends on many factors, as others have pointed out. It also depends on wheelsize. Most all of you have a 26" and larger wheel tunnel vision. 50/36T on a 20" (451) wheel is just dandy.

110/74 five arm cranks have been around a long time and I bet they'll still be around a long time, even while the fads of each year come and go

It's approximately true!

You're both lost. I'm comparing the gear spread with a 1X vs a 2X. The 1X requires a higher high and lower low to match the range of a 2X. Therefore, the gaps between gears are larger. Common sense.
No, he's right. These are MTB parts and the shift ratios on MTB's have always been about +-15%. With an 8-speed triple you get two more top ratios with the outer ring, and 3 more bottom ratios with the inner ring. With the 1x system you get the same middle ring ratios you always did, get the 3 granny gears via more cogs on the rear instead of the inner front, and lose the top two. Here's 11x11-40 with a 32 ring, compared to the 8x3 system that came with my Hardrock. The bolded sections are identical, the bottom is similar though not the same.
I don't actually shift it this way, I use the outer ring for the upper three or four and the inner ring for the lower four or five, because the chain rubs. But the ratios would come out similar enough because the cassette ratio spacing is pretty even.

A couple of annoying oddities about 50/34...
...the 34 is simply too small of a ring to do any spinning for any period of time on flats/slight descents.
...the 50 ring is surprisingly noisy. It doesn't make a huge racket, but it's noticeably noisier than the 34. I wouldn't mind if I were in the 50 only occasionally, such as for long descents, but there aren't any long descents where I ride.
50/34 is just wrong.
I can't believe 50/34 has been standard for as long as it has. I say either go with 10 or 11 speed 50/39/30 to get smaller jumps between rings and to get a wide gear range, or go with a 1X 12 speed or better yet, 13 speed. I would find a 40 or 42 paired with a 10 - 40 or 42 might be nice.

If change is necessary the new reality probably won't totally suck if we lose the 11 cog and a few thousand pages could easily be written about it like, just last month I spun out doing 32.1 mph spinning a 50x11 at 90 RPM... what am I 'gonna do now, drop down to 29.4 MPH with my puny 12t cog? Increase my cadence to 100? Oh wait... if I increase my cadence to 99 I can still do 30 mph in 13t so, never mind.

...doable: a 1x12 with the biggest available 38t chainring up front is 100.5 gear inches in the 10t cog and 30 mph if you can muster up 101 RPMs (I think could possibly do that with 145 mm cranks).

10-50 cassette? Sheesh, the thing must be half the size of the wheel. It is like its own dork disk.

If you have an aero rim you can't shift into the spokes
