Basic Maintenance Tutorials
Are there DVDs or other media formats, that visually show you how to do basic maintenance? Instructions sink in better when shown how step by step, and it would help to have a reference for basic wheel maintenance, chain & cable maintenance, and stuff like that. More in the line of preventive maintenance.
Do any visual tutorials come to mind? If not, is there a next-best-thing in the form of a publication with photos of how to do preventive maintenance?
