hey, certainly an interesting experience. Thanks for responding.
Does make me think just how neat the bicycle is as an invention-that allows us to move around rather efficiently, and can work with simple, robust systems.
Your setup and being a traveller for so long is not my thing, but it is yours, and you seem to know how to make a bike work for you and have a well working setup. I too have always been very aware of chain line and how keeping a chain running in line helps a lot, and I put on a fraction of the kms that you do.
safe riding on your journey
