OOPS.......just realised there is a specific section for fixies. Mods feel free to move or eliminate this. Serious question. Feel free to answer whether you or for or against but I am really interested in knowing WHY. The only one I ever tried was 50 years ago.........that one didn't allow you to stop pedalling (until bike had stopped of course). Not sure how I got off it still alive I just don't understand the concept i.e. why not have a choice of gears and be able to free wheel when you want to?
