On my tube, I have a pump.
On my helmet, I have an LED (for nighttime repairs/back up lighting).
Handlebars have an HID light.
Now, I have a 1 LED back up headlight on the handlebars as a back up.
As soon as Nashbar delivers it, I will replace the LED with a 10w halogen.
In my seat bag, I have:
10 mm ratchet
tiny 10 mm wrench (for breaks)
8 mm ratchet
Health Insurance Info
Folding allen wrenches
Electrical tape (wrapped around one of the ratchets)
3 AAA Batteries in case one of my back up LED's fails.
