I follow a few communities which have a lot of fixie and single-speed riders. Most of the riding discussed is commuting around the city, and often, riders will show off their new bikes, upgraded hardware, or will post photos of parts needing maintenance, seeking repair advice.
I've noticed that many of the bikes are in fact track bikes, based on the track fork-ends where one would normally find dropouts.
Does using a track frame for day-to-day city commuting have any drawbacks, either for the rider, or for the frame itself?
