Just an FYI, I ended finding new X Series V2 cleats for $40 on 'da-Bay and Colorado Cyclist. My LBS stopped carrying Speedplay altogether. I made a similar inquiry here a few months ago; the Zero series seems to more dominant these days. I have two sets of X and Zero pedals each, but only pair of X cleats.

How about $40 including shipping (CONUS) for a new set?

Are these the model you're looking for? I could do $25 shipped
