Took my seat bag off so I could clamp the seatpost in my repair stand and thought "damn, what can I do without to make the seat bag lighter?" I could not think of anything, even tho some I've never had to use--ex.- chain breaker. I know many of us may not even carry tools on shorter rides. But on rides where we feel the need to have tools with us, are there tools you carry that you never use, but don't feel you want to do without?
