The more you ride a bicycle the more likely it is to get a flat tire. It is a good idea to carry the tools needed to fix a flat tire (tire levers, spare tube, multi-tool, etc). I do not carry a pump, instead carry a small CO2 nozzle and two CO2 cartridges in a seat bag. I carry two cartridges because of the situation where one was not enough and it took a long time for help to arrive.
