Love the bikes on your site, and used many of them for inspiration when building up my daily commuter. It is a custom build by Tati Cycles (www.taticycles.com). I ride it all year here in Chicago. The pictures are of the 3 main configurations I use throughout the year.

Configuration 1 is front and back racks, wood fenders, and Rivendell Jack Browns. This is how the bike was originally conceived for its main commuter duties.

Configuration 2 is for cross races. I take off the fenders and racks, and replace the Jack Browns with Schwalbe CX Pros.

Configuration 3 is for commuting during cross season. Right after the race the racks go back on.
