Take a pencil and cut it in half, then wrap duct tape around it till it suits your future needs and place it in the little side compartment in your saddlebag. I use duct tape in conjunction with left over Tuffy liners from whatever bike I had used it for; by patching blown out sidewalls on tires (a generous size). Save my butt and some friends of mine a few time. Always squeeze the contact cement tube from the bottom up to take out any air bubbles after patching tubes; on the road or at home (this ensure you that the next time you have to use it; it won't be dried up). Always carry three tire irons with you when a new tire is being used.
