Subcompact Doubles v Triples
So it looks like the Franken >Lake Garda tour is going to happen this summer barring any unforeseen circumstances.
I'm not inclined to take my Cross Check since it's going to require more weight than that bike can handle without becoming too flexy so I've drug out my Rock 'n Road frame. My parts bin is fairly deep so I can build how I like which leads to my question...
If you were going to build a bike to cross the Alps with say 50ish pound of gear would you build on a mountain triple 44/34/24/6 or go with a 44/28 double, if I go triple I'm going to use barcons and 11-36 10 speed if I go compact double I'll probably go 11-42 11 speed double tap. In day to day use I don't use that big of a cassette because it's not needed and has some holes in the cassette stack that make me uncomfortable, but on a ride like this I can deal I think.
I don't love barcons though I have no issue using them but If I had my druthers I choose integrated shifters, the flip side is my brake levers are long pull so I'll be able to use full length linear pulls v mini's since this bike is going to be built around 32mm tires I'm not sure that will make a difference but it exists.
When push comes to shove I'll be able to ride the route with either setup and since I own all the parts cost isn't a consideration. I'm leaning triple since i'll have a closer spaced ratio but I don't know if that's a benefit over a change of hand position to make it work.
So would you choose traditional or modernish for my ~600k est. 10 day trip?

Another idea. The brifter is optimum for the close spaced 10-speed. (I'm assuming - I haven't gone brifter yet and not more than 9 but I'm not sure I'd want to friction shift more than 9.) So put on the 2X brifters of your choice. Now, park a SunTour Command left/front shifter right behind the left brifter and run the triple off it. It's just a friction shift; nothing fancy, but it works well and is good from the levers. I ran the Mooney fort years with the Commands. Right wasmarginal when SunTour FWs got scarce. Sedis/Sachs didn't quite index properly. The front simply worked.
This would give you the triple and it's nice cassette and range, the nice brifter shifts for the rear and keep your hands where they should be (you do need to upshift to the bigger chainrings from the levers or behind, not the drops.)
If you wanted to go this route, I've got an NOS pair I believe and a well used pair that is marginal on the rear but just fine in front. (Index was never SunTour's forte but friction they did with the best.)
Edit: Germany. So that shifter would have to cross a continent and another great ocean.

My derailleur touring bikes, my rando bike, and my errand bike all have triples.
My road bike has my only double crank, I bought that as a complete bike and it came with the double.
So, my highly biased answer is ... <sound of drum roll>, ... triple.

Going through the Alps with 50 lbs of gear on a fairly heavy bike to begin with, yea, I would need a really low gear to protect my knees.
It would have to be a triple for me to get that low of a low and not have enormous gaps between gears and/or not having an adequate high end to go with it.

Lowest gearing. 50lbs I hope includes the bike weight.

I would use a mountain double instead of a compact road double. Triples are obsolete in my opinion. I run a SRAM mountain 2x11 drivetrain on my bike, bar end shifters.

I'm biased towards triples, and find the 32 or 34 mid ring and 24 or 22 small ring to be very very versatile for loaded riding, very much moreso in mountainy terrain--,of which I've done a lot of.

Lago De Gurda is just down the way from several bicycle manufacturers. Not to mention the little shops in around Verona, and of course the Campy plant in Vicenza. Why don't you just pick up a used bike over there and save yourself some money. Also if you want a set up for the mountains consider the experts in the shops around Bassano Del Grappa.

whichever setup gives you the most usable gears, especially at the low end, is the way to go. for me that means a triple for more variety.
nothing obsolete about triples. they remain useful, particularly with loaded touring. it's decidedly frustrating to be unable to find the right gear.

Being a 34t and 24t in your case make these two chainrings even a bit more versatile, as the speed range vs my 32 and 22 is even a bit higher--and possibly even higher with 700 wheels. I have an old 700 wheeled bike with a cheap crankset of 42/34/24 and the 34 ring and bigger wheels (so higher gearing) allows me to go that bit faster in the mid ring than on my 26in touring bike with the 44/32/22
the only downside to a mtb triple is if lightly loaded, you sometimes have to shift more between big ring and middle ring, its never really been a problem with my touring, but when touring much lighter than usual, I have at times wished for a bigger mid ring---which you do have and may have taller wheels also, so higher gearing overall.
my touring bike has a 9 spd 11-34, but my wifes bike has 10 spd 48/36/26 and 11-36 (same you are thinking of using) and the jumps between her 11-36 and slightly closer than my 9 spd 11-34, so this is a really good touring cassette.
you'll have to look at a gearing chart for the 11 spd setup to see how they compare---this is the most important thing to do, see the actual black and white numbers , both the actual gear inches of the gears, but also the percentage in steps between each shift---maybe the 11 spd setup is almost exactly the same, but perhaps not the same low--important perhaps to you if you really are carrying 50 pounds of gear (and not 50 lbs of bike AND gear)
do the gearing charts and show them here bitte.

chris, heck I just looked at the gearing charts for both, and while there are different cassettes with diff cogs depending on the company, it would appear that it is likely the 10 spd 11-36 and the 11 speed 11-42 will have the same cogs except for the added 42 on the 11 speed----so in other words, the same jumps
so I take back what I said, and if you can get the brifters to work properly with what parts you own, heck why not go with the brifters--they certainly are super nice to ride with.
I couldnt help myself and did screenshots of the two setups, which btw I see the frame is 700 wheeled, so others can see the range and easily the percentage jumps between the shifts

do 11 speed drivetrains wear out a lot faster with more cross-chaining than 10 or 9 speed with less cross-chaining?
is this a problem or not a big deal?
is 11 spd + more susceptible to chain breaks? or not really a big deal unless you are a bull in a chinashop with how you shift?

Either set up will work, but I like the simplicity of a double. I have a 42/26 using the two inner rings of a triple and a 11x34 cassette on one bike and it works just fine and it would be easy to go to 12x36. Look at lightening the load as well as lowering gears. With a light load I used a 46x34 with a 12x36 cassette to do the Northern Tier and I'm not a particularly strong rider.

The 26 tooth chainwheel, however, doesn’t give you a very good low gear.

The 24 tooth chainwheel would give you a similar low gear to the 2x system with better shifting.

But there is no issue with going to a standard mountain bike 22 tooth inner gear. It’s not going to tax anything on the drivetrain to use that gearing. It will work with a minimum of fiddling.

Now let’s go to Crazy Town! It’s possible with a little bit of filing to get a 20 tooth inner ring to work on a 64mm BCD crank. I’ve done it with several bikes. That drops the low to almost (but not quite) stupid levels. This is gearing I currently run on my touring bike. I am using a Wolf Tooth Roadlink to increase the range of the 9 speed derailer I’m using.

If you want to follow me further down this crazy hole, I have also used a 40 tooth low gear with the 20 tooth inner on my bikepacking bike (mountain bike with 26” wheels so it’s even lower). I did that without the Roadlink and have to tell you that a 14” gear gets you nowhere fast but it does get you up a whole lot of steep things. I have a 42 tooth low gear that I haven’t tried yet because I need a Roadlink which I haven’t tried yet. A 14” gear is already kind of silly.

Go triple. I have an 8 speed 42-32-22 with an 11-34 cassette I installed on my 99 trek 520 and it’s a great set up. When the triple front crankset wears out im gonna swap in a 40-30-22 for what I speculate will be an even more useable overall range (since I very very ever rarely spin the 42-11 combo). I know with this crankset set up I have a very useable gear range on all 3 chain rings on top of great chain line as well.

When a lot of people are still recommending triples, they are not obsolete.
It is unlikely you will find anyone recommend cup and cone bottom brackets or headsets, that means that they are obsolete.

And if I'm going downhill at that kind of speed, I'm already coasting long before I get to 30 mph. That large chainring would never get used.
If one really wants to ride fast on a double, one could simply use a modern hub that allows for the use of a 10t small cog. That 11t to 10t change on the cassette is an instant 9% increase to the top speed.
I could see the argument for using a triple with a closely spaced cassette, to have less jarring ratio changes between gears. It's a more compelling argument than getting a useless ego-boosting fantasy top speed.

I'd go 42/34/24 triple. Play with that calculator cyccommute referenced. It is fun and enlightening. Slide the chainrings around to minimize duplicate gearing. As near as I can tell, people think triples are obsolete because nobody could figure out how to make them index well so they stopped offering them widely while trying to convince everyone they are obsolete. In friction mode, even without ramps and pins, a triple shifts just fine. Don't worry about matching chainrings because, as cyccommute mentioned the manufacturer pairings make little sense. Play with the calculator, choose the rings you want, put them on with an old Suntour front derailleur in friction mode and it should all be good - more range, closer steps. You're touring, double shifting to get just the right gear is no big deal once you figure out the shift patterns. The chart helps you visualize that.

But I get it that there are a lot of triple cranks out there on bikes and some people like them. It's sort of like manual transmissions on cars - yeah, you can get them but your choice is really limited, you can get it only on a very limited number of models, and it's around 2% of the market. That's kind of the situation triples are in only probably worse and way less than 1%. Is that obsolete? Maybe not but pretty close especially since there's some other technologies that fill the bill at least as well.

As I said early in the thread, triple fan here. I love the close gear spacing without having to do double shifts all the time. I like having enough overlap between middle ring choices and both big and small rings if I can do it so I can ride long, slightly varying grade stretches on one ring. And I like having a big gear if there are going to be either big time tailwinds or downhills. Losing out on an all day tailwind because I have nothing bigger than 85"? Passing up a shot at heaven on Earth? And big downhills - pedaling that big gear can do a lot to stabilize speed wobbles, including wobbles that come from the load the bike is now carrying. So that big gear might allow higher speed or just lower HR.
Big ranges plus great choices without double shifts is getting into un-ubtainium but triples allow you to get closer. Obsolete" Well, the manufacturers are doing their best to make them so. I'm hoping enough of us stay triple that enough makers see us.
