As I read more about touring through Latin America, it seems that most countries have something in common. The lack of good bicycle parts that one might find throughout the US and Canada.
Anyone with touring experience through Central and South America, how did you cope with this? Do you stock up on spare parts (components, etc) and leave them back home to be sent or do you bring them with? Any tips on what will most certainly not be found?
I figure the things I will have to worry about finding are the things that fall prey to normal wear and tear, like derailleur, chain, and cassette, but tires should be easy to find.
