..i guess the numbers are not about the picture. It would appear very different in 37-451. But i would love to know how the owner managed to prepare the fork steerer tube to work with that short-clamping handlebar stem. I did that before, so i know about but i'm very curious how others did.
..sorry for OT

I put a Sram Dual Drive on my Airnimal Joey. That is a three speed internally geared hub that has a standard 8 or 9 speed cassette freehub. Sram took that hub out of production a number of years ago, but it is my understanding that Sturmey Archer makes one like it.
The reason that I mention this is that in high gear on the three speed hub it is in an overdrive mode. You could use a standard 8 or 9 speed cassette with a small sprocket of 11 teeth and get gearing higher than you would with a 10T sprocket on a standard hub.
But since I am ignorant of the Sturmey Archer, others would have to elaborate on that. Not sure what hub spacing you would need, the Sram that I have fits in 135mm dropouts. And this would also be an issue for your budget.
If you are racing with roadies, there is some extra drag in the hub, but I can't feel it. For recreational riding, I think that such a hub is great.

It is my understanding from other posters on a different forum that the Sturmey Archer dual drive hub, although sold as 135mm wide has several locking bolts, one of which can be removed for use in a 130mm wide dropout without any issues.

I prioritize climbing so top end gear-inches in the 80s is perfectly fine for my terrain and riding style. Ergo, 50t is as big as I would need and install on a 406er. I once had a folder with 120-odd gear inches at the top. That was a total waste so I went to 1x and a more limited gearing range.
I'm into climbing as well and I live in amongst some high mountain ranges. Right now my Swift is set up with 406 wheels and 56_11-42 gearing. Personally I think that maybe the 11-42 cassette is a bit more than I actually need - I did all the same mountain roads with 56_11-36 last year and it was a little lighter. That said I do like having a big ring in front. These days it's easy to get a very good spread of high to low gears on the cassette, so no need to keep it small up front for the mountain imo.

Touring is not about speed, but rather endurance and proper pacing. It's more about spinning and cadence than mashing and speed. Cross a country loaded up spanning weeks and we can talk.

I've been in the area where you are, the Granada, Ronda & Alpujarra environs. I know it's quite mountainous with the highest peak in Spain. One day I hope to base myself in Ronda and cycle each day.

I actually toured with a 11-36t cogset in South Korea, and that was fine (ironically member 2_i questioned the use of only 11-36t). But for other places, volcanic places, I'd definitely need more than that.
