I find that a little folat is introduced over time as everything wears. But new cleats and good pedals = no float.
Due to the shape of the rear engagment plate the DX's do actuall have a fair bit of float, another reason why they are on the Pace as I ride that most often.
Somerset, like 'Heartbeat' with newer cars!
