A lot of people - including the FredCast guy - like to think that Fred means somebody who likes the latest techie bike stuff... GPS, Di2, powertaps, etc.
But Fred simply means a dork or a geek on a bike... doesn't matter how much of that stuff you have or don't have but it does sort of imply that you act as though you're a better or more serious rider than you really are.
So to not be a Fred - don't act like one, don't look like one, and it doesn't much matter what you ride (within reason).
