Here are a few pictures of my KHS Aero Track, my favorite of three fixies. The front wheel is a 650, the back wheel is a 700 campy aero rim laced to a Maillard track hub...my first attempt at wheel building, and it was a lot easier than I thought. I got some pointers from Keith at Cavern Cycles in Toronto, where I picked up the frame and most components, including that sexy fork. So light and agile it makes me ride like a cocky jackass...this bike is trouble.
