Some fixed gear blogs I have recently started following:
TableRockCycles: Fixed gear mountain maniacs down south somewhere. Great scenic ride shots and a good quantity of bike porn.
Fixed Gear Maniacs: The latest on the fixed gear scene in Miami, FL. Check out the post on 10 Reasons to Ride Fixed Gear.
Lastly, another blog from Maine, describes everything you might want to know about fixed gear riding. Kind of hard to read with the size of the font, the white background and the font color. Or maybe I am getting long in the tooth?
