I'm getting things for my touring toolkit. So far I have:

- spare tubes for bike and trailer
- Road Morph pump
- zip ties (the universal bike fixit)
- tire levers
- multitool
- Clif bar wrapper for tire boot
- small first aid kit
- spare cotter pins for trailer

I'm ordering a kevlar spoke in case I break a spoke on tour. Should I get two or more, or is that overkill? And Park makes a compact chain tool. Is that also overkill for a touring cyclist?

Anything else I should consider?
