If you want the fastest bike, get a fixie. If you want your bike to do anything else, get a touring/commuter rig. Road bikes are useless, they’re heavier than a fixie and have no rack or fender mounts. There’s really no practical reason for anybody besides athletes to have a road bike, since a road bike shares nearly identical costs and maintenance schedules as a more practical touring/commuting bicycle, with none of the necessities like rack/fender mounts, or kickstands, and much more aggressive and less comfortable geometry as well as stiffer materials, resulting in a bumpier ride.
Here’s the part where you might be asking, “well what about the fixed gear?” Glad you asked. That thing requires a regrease once a year if you actually care for it enough and/or don’t blow all your money on new bike parts all the time cause you keep breaking shit after launching off the nearby 4 stair.
