- One or two spare tubes.
- Set of plastic tire levers, (I've never needed to use more than one).
- Mini-pump to get tire filled enough to ride to next gas station with an air pump.
- Schrader/Presta adapter, (for when I get to that gas station).
- Pack of Park self-adhesive patches.
- Pack of Park tire boots.
So far, I've never needed to use the last two items.
I don't normally carry a spare tire except on century rides, but after recently encountering
a guy on the road who was mounting his spare, I'm thinking it might be a good idea.
