I just recently got my first bike, and now I want to put together an emergency kit before I go on any long rides. What do you guys generally carry with you? I obviously want to carry as little as possible, but I also want to be prepared. Here's what I've come up with so far:

pump (strapped to downtube)
multi tool (possibly this + additional tire levers)
2 spare tubes
patch kit
(cell phone, ID, etc.)
in this (small?) saddle bag

What am I missing, or where could I do better?
