Another problem with such guides is that they may have good instructions regarding "how to do something" but most aren't much on telling you "what to do". You can pull your hair out struggling with a rear derailleur adjustment but, if the problem is a bent derailleur hanger, they don't tell you that.
The problems mentioned above are solved with Barnett's Manual. I can personally attest to the excellence of this manual. I've owned a few others, including some that have been mentioned here and, IMO, Barnett's is head and shoulders above the rest. From the website:
"Barnett's Manual DX is simply the most comprehensive resource ever published for bicycle mechanics. Digital publication enables us to publish new editions that correspond to every new equipment model year, whereas the discontinued print version could only be updated about once every three to four years."
With unlimited downloads for life!
