Thought this was a neat atricle about tracking Hipsters and "fixies" across the country and some other interesting city cycling Comparisons. I am pretty sure the "Chico" on the charts are supposed to be Chicago, Just a guess.
I think Chico means Chico, California and we aren't actually looked at. There is no way that San Fran with all those hills has more fixed gear riders than our lovlely flat city.
