Shelley created this as a little take home instruction guide for her bike repair workshop at the Portland Zine Symposium.
It goes over the basics of fixing a flat tire, working with wheels, the parts of a bike, bearings, doing a tune-up, tools, and dealing with bike shops as a woman but most of all what shines through is Shelley's character and personality in the way that she describes things and her utter passion for cycling.
This is a thin zine, only 32 pages, but it's packed with great info.
