I like to use my bike for transportation, to and from work and visiting local stores. The biggest downside is when I want to make one or more stops in the trip. I live in a neighborhood with a lot of bums and they will steal anything they see and think they can sell that isn't secured, including bike accessories. This means I can't simply have a tool pouch and pump that I ignore until I have to make a roadside repair. They have to be removed and taken with me at every store I might visit. Until now.
I bought a Post Pump for the pump issue and the patch kit is in the seat post tube.
This left the allen wrenches and screwdriver. I was carrying a multi-tool in my pocket but wasn't satisfied with that and was trying to think of a way to stash it somewhere on the bike, to no avail. Until I saw the Kickstarter for Fix It Sticks. I now have everything I might need for a roadside emergency stashed, except for the crescent wrench.
Things you'll need.
A paper clip.
Some strong string.
Some thin padding.
