That stuff will let me fix nearly any flat, regardless of how tight a tire might be on a wheel, and will get a broken chain going again. I also have light medical stuff (bandages, and healing cream) and my daughter's inhaler when we go together. I may also add a brake and shift cable to the bag and a small pair of needle nose pliers with snippers. This stuff weighs hardly anything, and I'm already carrying the trunk bag anyway. And then my phone and wallet and keys go into the trunk also.

I don't carry this stuff as much for me, but to be able to help others while out riding.
