Cell phone, cash, credit card, ID in a baggie.

I'm currently riding some fairly deserted roads near Madrid, Spain, and I'm traveling solo. My "travel seat bag" has a whopping two tubes, 4 or 5 CO2 cartridges, boots, and a small multi-tool in addition to the stuff above.

If you look your bike and tires over before you ride, you don't have to go crazy. I keep waiting for somebody to post a picture of their BOB trailer with the spare bike on it, just in case.
