There are definitely expenses associated with cylcing. But good quality cycling stuff is cool so it's fun to buy. The way I look at it is if I did not bike for transportation, I would incur the cycling expenses anyway since I bike for recreation as well. This way I can put to use the stuff I buy for fun. In the meantime I save all the money I would spend if I spent my life behind the wheel of a car stuck in traffic in some god awful stretch on eight lane hell.
