I'll soon start a rather long trip from Ushuaia to Alaska. As I'm from Europe (France), I don't really know what to expect about spare parts for my bike in South America.

I'll ride a Kona Rove ST, a gravel bike with 650b wheels and 47mm wide tubeless tires. The train is 1x11 SRAM. How easy do you think it will be to get new tires, gear parts, tubeless sealant and other spokes?
