Every tour I seem to bring a different set of tools. I don't have a photo, but this is what I brought on our summer trip up the Blue Ridge Parkway:

1. Fix It Sticks tool with only the bits to service our bikes
2. Fix It Sticks chain breaker (this thing is as good as a shop tool but still compact)
3. Park No. 0 spoke wrench
4. Tubeless tire plugs and insert tool (both of our bikes were set up tubeless)
5. Spare tube
6. Pump
7. Rag
8. Chain lube
9. Spare Shimano 11s quick link
10. Pedros tire lever (the best)

The only mechanical we had mid tour was a slashed sidewall, which I fixed with a dollar bill and the spare tube. The Fix It Sticks came in handy for (un)boxing the bikes. I don't think we ended up using any chain lube because both chains were new at the start of the trip.

I continue to be impressed with the Fix It Sticks tool. It works like a dedicated shop tool but is as compact as a lot of multi-tools with inferior functionality. The only downside is the potential to lose the removable bits, but with care it hasn't been a problem yet.
