Hi! I wrote the post. I had a friend talk to me about tubeless before I went, and I'm happy I didn't do it. The sealant would need to be replenished. And the first real gash would mean going back to a tube. I was super happy with the Tannus liners (13mm of protection) despite adding some weight and rigidity (the bike was already a tank).

Considering this, a tubeless sealant top-up at each of these visits would have been no extra chore. Just sayin' :)

Gotcha! It was impressive how fancy gear mountain biking is popular in all the big cities along the Andes. They "road bike" on MTBs a lot. In Colombia they are nuts for cycling and have some seriously pricey rides. Definitely the sealant is in all the big cities. Some of my tune-ups were in small towns.
