While learning about cycling, I researched as many articles as I could find online. Whenever I found agreement or consensus I considered that good advice and I eliminated outlier viewpoints.
The three how-to-cycle articles posted here all agree in principle and, to a great part, in the details. The three articles are by Olympia, OldFishLady and imntbatman. Nobody reading these should be confused; in fact the reader should be further enlightened and educated in cycling lore.
Bahamut's illustrated guide teaches the fundamentals of the the nitrogen cycle that the other three articles show how to do. It is an important, in fact indispensable addition to the 'how-to' guides.
