Derailerless drivetrains

New article, derailerless drivetrainswhite_hub250: How to choose frame and rear hub for a happy combination on a bicycle without derailers: a fixed gear, singlespeed, internal-gear hub, coaster brake bicycle — and how to adjust the chain tension. This article compiles information from the articles on fixed-gear and singlespeed bicycles. but adds to it and puts it in one place. Most issues with all derailerless drivetrains are the same, but there are important differences to note, there is new equipment to cover, and there are additional techniques to describe.
