Is this a tell all about all the products including wax for lubing your chain and related moving parts like your rear derailleur? No, it is most definitely not.
I did go and actually lube my bike chain (no idea if the following picture was before or after the chain being lubed)
The important part about oiling your chain is immediately testing it by setting out on the longest ride you feel comfortable with. I took my bike across I90 and over to Grand Central Bakery on Eastlake and then back.
What a gorgeous day!
