My Father always told me, "Keep a complete set of tools in the trunk of you car. If you break down, even if you don't know how to fix what's broken, someone who stops may know how. Without tools you're both screwed". Thanks to the old man, that advice has saved me a few times. I've taken his same advice and try to accomplish the same with my bikes.

Space is always a problem. I like the Swiss Army knife approach, getting the most tools per square inch is always the solution for me.

Pit Posse has a compact, slick and inexpensive multi-tool selling for only $14.95.

They have a metric and SAE models of the same. The sockets sit loose in the handle and can be swapped out for your own sockets for sizes you know you will need.
