Surly Steamroller

Another simple solution from Surly. The road bike with only one gear can also be driven rigidly, meaning without freewheeling. Single speed, as the Yanks say, can be taken literally. Single speed means in this case not only a gear but also a speed. You have to think carefully about the choice of gear ratio; otherwise, you're either not fast enough or you'll kick yourself to death. Your ticket to a fascinatingly simple world.
