If the bike is for cycle camping I’d be very reluctant to go 1x.
I’d favour 3x mtb gearing, or at least 2x with something like 44/30 x 11/36.

1x on my touring bike over my dead body. I’m not going to explain or reason, it’s just stupid. I run 3 x 10 105 at the moment on the road tourer and 3 x 10 XT on the MTB. 2x might work but that would be the limit and would be a deference of function against modernity and market availability.
1 x 11 SRAM on my 29er was inferior to either 2x or 3x for my riding (natural trails and mountain routes in the Highlands, with tarmac sections)

I use 22/32 at the front, 11-36 rear on 29+ wheels.
Works fine for bikepacking. I’m a spinner, as i no longer have much strength in my right leg after an accident.
9spd xt rear mech, over a 10spd cassette, pulled by bar end shifters mounted on top of the bars.
Works superbly.
I also, would be hesitant to go 1x on a bike that is ridden fully loaded.
For a trail bike, I probably would.

Tony, here’s a review of Sram Eagle but with a bikepacking slant – http://www.bikepacking.com/gear/sram-eagle-review/http://www.bikepacking.com/gear/sram-eagle-review/ the arguments for and against shouldn’t be too dissimilar for touring.

However, much as I’m a 1x fan, I don’t think I’d go 1x for a touring bike – on the road and especially on a loaded bike you want a good set of close ratios across a wide range. The 1×12 Eagle systems give you the range but not the close ratios.

Where as I’m exactly the looopposite of swanny.

I want the right gear. I don’t want to be constantly switching between a gear that’s too high and one that’s too low.

I run deore touring triple 26/36/48 and 11/32 out back . Lots of over lap but equally lots of choice to find the right gear for that bugger of a. Headwind/hill/sore knee you have been battling with for the last 8hours. -and plenty top end to sprint to the next village before the shop shuts.

But then that depends what touring is to you. 4 panniers and crossing the Rockies is a bit different from an over night up the road 20 miles.

I went 2×10 Deore 28/38 & 11-36 SLX cassette, went for XT hubs, BB and chain. Chain line is better for the gears I use most, I gained two lower gears over the triple I took off, and lost 1 higher gear I rarely used and won’t miss.
