Whether you ride on smooth pavement, gravel tracks, or singletrack trails, at some point you will definitely get a flat tire. That means you need to prepare yourself.

 

For tools, you should always carry a set of tire levers, a correctly sized spare tube, and some kind of inflation device, be it a pump or CO2 cartridge. You may also want to get a patch kit or tire plug, which can certainly come in handy if you run out of tubes.
