Three years 'on the road'. That means road-side repairs. I selected all the tools that I needed and got rid of the rest (you would be surprised to see how little you actually need to completely disassemble a bike). Naturally a toolset needs to be stored on (or in) the bike to be of any use, and not (as I found out in the Indian desert) in your hotel room. It can be rather frustrating to realize that your tire-pump is 20 km away when you look at a flat tire.
