Did a bit of searching on this and no info found. Is there a converter to go from a three hole pattern to SPD? I have a pair of shoes with three holes and am considering Bebops, which need an SPD bolt pattern.

There you go, thanks. I looked on a few retailer's sites but not Excel. Turns out I ended up ordering the Keo Carbons.
