As much as I love bikes as a whole and broken into the components, I just cant get into chains.
I geek on geometry theory, frame materials and design, as well as the mechanics of components...but chains are just a total bore.
I made it only part way thru the article before I started scrolling for something interesting. I made it halfway thru this thread before scrolling for something interesting. Its a chain- clean it from time to time and replace it when its worn.
A chain is the pinky toe of the bike. Chains are boring, plain, and forgettable...but vital to proper operation of the bike.
