Just to confuse you even more, Speedplay has come out with a new pedal and cleat that swivels less or can be fixed in place. I suppose it is for those riders that don't like the swivel with the regular road versions. I personally think the swivel makes me a smoother pedaler and it took me a ride or two to get in sync. I'v had them for 5 years and love them. Doubt if I'll ever go back to anything else.
