I built up a single-speed/fixed gear Centurion last year and find it a lot of fun (and plenty of exercise) to ride. I generally use toe clips, in this case on Shimano 105 pedals, but my son, who also rides a fixed gear bike, says I'll have more control with clipless pedals. In particular, he showed me how to lift the back wheel while stopped and pull on the pedals to reposition the pedals for starting off. My question is this: Without starting a religious war, what pedals do the fixie folks prefer. As an aside, for me the most important factor is how quickly I can release my feet from the pedals. Thanks in advance.
