I have a geared bike for distance, recreation, and fitness riding, and a fixed gear bike for riding to work. Tune-ups are expensive for us common folk. Yeah yeah I can tune it myself, but I can't dial it in like a shop can. Fixed gears take less maintenance, and thus are better for short distance rides around town. Now, why do people ride long distance on fixed gears? I dunno, to be badass? So you can worry less about parts failing? Maybe people enjoy the challenge of getting from point A to point B by the power of their own legs without the assistance of derailleurs. What's wrong with personal preference?
Someone EDUCATE me on why RASPBERRY jelly is better than GRAPE. When I'm with my friends at a group PB&J and someone brings RASPBERRY everyone makes a big stink about it, I'm like so what?
