Not being a Kantian, I'm not sure if this list requires some sort of deontological adherence. After all, rule #90 violates our beloved SIG Capt'n George Arcarola's explicit RideSmart wisdom:

"Rule #90// Never Get Out of the Big Ring

If it gets steeper, just push harder on the pedals."

Derailleur is pronounced de-ray-yoor. Derailer is spelled derailer (G-d bless you and keep you, Sheldon Brown).

The rap is great, 

"The cog is the sign, the bike is the tool, Eddy is prophet, Obey The RULES !!"

The text to rule 40 is simply wrong:

"Tires are to be mounted with the label centered directly over the valve stem. Pro mechanics do it because it makes it easier to find the valve."

Ummm...no. If you can't find the valve easily, see your eye doctor. Mechanics position the label so that when you find the hole in the tube, you can find the corresponding place on the tire, and remove what caused the puncture. For this reason really astute mechanics will also mark the right side of the valve stem.
