The world of fixed-gear riding is a fairly simple one. With only one gear and usually with no brakes maintenance on a fixed gear bike is minimal. However, there's always the fact that you don't have brakes, and this is where the skid comes in. A simple way to make your simple bike slow down, being able to pull off a skid is one of the fixed-gear rider's most important skills. Check out pro-rider SDG Lucas as he pulls a few skids out on the street and take notes if you haven't already figured out this simple maneuver, it may just save your life one day.
