- Wet lube + rag / cloth Lube--yes. rag--no, you can use paper towels or napkins you get along the way
- 1x spare inner tube Yes, definitely. I'd take two.
- Multi-tool Yes, as long as it is bicycle specific and is has only what you need (i.e., is one of the smaller ones)
- 1x spare brake pads Yes, maybe even two sets
- Hand pump Yes. I prefer one with a built-in gauge like the Topeak Road Morph
- puncture repair kit Yes, definitely
- Spoke tool Yes, although the multi-tool usually has one
- Chain tool Yes, although the multi-tool usually has one
Other things:
- Something to fix a broken spoke. The minimalist approach, which is sufficient for most problems, is a FiberFix or two. Get a real spoke at the next bike shop you come to, and put the FiberFix back in your kit for later reuse.
- Tire?? Probably not needed if you start the tour with new, high-quality tires. But if you have crappy or worn tires, you probably want to take a spare.
- Tire lever(s) to remove tire when you fix a flat. The multitool may have one or more.
- Spare bolts for your rack
- Spare cables, one of each brake and derailleur
- Something to serve as a tire boot, like a 3" piece of an old tire with the bead cut off, or maybe just a piece of Tyvek
- Spare master link or two (in case your chain breaks or gets mangled)
