Just curious as to what the reasons are you ride fixed. I see a fair amount around here in Madison, WI.
I am one of those old-school "roadies" and I have one exclusively for winter training, and nasty weather commuting, geared 44x17. In WI, winters are nasty, slushy, and salty, and destroy a more complex machine in short order. 2000+ winter miles cost only 2 chains, a chain ring, and 1 severely chewed DA cog.
What makes you ride one of these archaic machines? I hope not everyone is as strictly utilitarian as I am.... I am sure this is not the case.
