You guys talking about "smoothing our my pedal stroke" do know there are many out there ready to debunk your theories?
I, of course, am not one of them.
I like fixed gear riding. I also have the makings for several single-speed bikes to build up when I get home. The simplicity is wonderful, and the workout is great depending on the gearing and terrain. My legs were strongest and my centuries fastest on a geared bike after an extended period of riding fixed.
