I've just got a couple questions about fixed gears. I've been riding road bikes for a while, but I want to add another bike to the garage. I'm looking at an 06 (i think, if not, then it's an 05), Bianchi Pista for $400. I was wondering about the flip flop hubs, can you just pop the wheel off real quick and flip the wheel around? Or do you need a couple wrenches to do so? The guy says it has a flip flop hub but needs a cog for the freewheel side. Do you think this would be a good starter bike?
