I wrote on these pages about purchasing the new Wahoo Speedplay pedal when I was putting my revised commuting bike together. Now I've had 10 months on them I thought I'd reflect on how they were going.
Where the Zero and other Speedplay pedals of old required regular lubrication of the spring for movement within the cleat and for the spring against the pedal, the new Speedplay suggests you may wish to lubricate (with a dry lube) but it isn't required. I ran them dry. Because the top of the pedal is now encircled in a steel ring, there has been zero wear to date. I think the old cleat was a soft plastic and the spring would eat into it if it was run totally dry. The new cleat is steel so there can be no wear - steel on steel is already pretty low friction. And the movement is rotation through a small number of degrees.
So that's a big improvement in my book.
I installed a new set of cleats on my newest shoes. They clip in just the same. They clip out about the same (I haven't done back-to-back testing to compare). Riding feel is identical. The new cleats work perfectly fine with new and old pedals alike, just as the old cleats work fine with both pedals too.
In February my right pedal developed a little bit of side-to-side play in the bearings. Unlike old Zero pedals, the new ones are not user serviceable, nor user lubricated. So there is nothing to come loose or adjust. This was a problem. Pushys to their credit replaced them promptly.
It turns out there is a laser-etched serial number on each pedal. It is SO tiny I had to photograph it in good light and zoom in on the photo to read the digits. I provided a video showing the play in the bad pedal and the serial number and they sent me a whole new set of pedals. I hope if anything goes awry with these that it is the left pedal this time so I can mate the old left with the new right and continue with a fully working pair.
I don't know if this is anomalous, or if they are fragile. Wahoo was supposed to increase the bearing size for durability, so I hope it is the former.
I would have to go back to an old pair if I couldn't continue using the new Wahoo variant. None of the other pedal options work for me. I have tried the Time, the Look and the Shimano and not only do I dislike the plastic cleat (but could live with that) but they generally sit way too far forward on the shoe for me. Wahoo no longer sells the plate, but I have 3 sets of the old Speedplay rearward cleat adaptors. They allow around 15mm more rearward placement (and 8mm more forward placement) of a Speedplay cleat on a 3-bolt shoe. I push the cleat back around 10mm further than the Northwave shoes permit on their own. (I could go custom shoes with custom hole placement for any pedal system but I would dislike going down that road.)
 
Check back in another year to see if my trial with the Wahoo pedals continues to be OK.
