looks like an interesting concept. i don't see why it wouldn't work.

that said, i haven't had any problems with my dual sided entry speedplays.

Well, the main selling point seems to be ease of entry, however, it seems like the rider will be fishing around a lot trying to align the channel in the cleat with the pedal. It's pretty easy to do this when you are holding the shoe in your hand and can see the pedal, but not so much with the shoe on your foot and can't see the pedal. Getting into SPD pedals is very easy, you just stomp down in the general vicinity on the pedal and that's all it takes.

I use downhill pedals on my steamroller. I could use clips and straps on 1 side because they only have 1 engaging point then the other side is a platform. Even with only 1 contact point to clip in it's super easy to flip the pedal and clip in within seconds. These pedals don't really appeal to me even though they are kinda cool.

yeah, i wonder how easy it is to find that groove.

Back in the 1970s before Look introduced their version of clipless pedals, Cinelli first introduced a version that was named the M71. It had a similar system, where the rider had to align grooves in the cleat with channels in the pedal. I used them only for track racing, because they were very difficult to get into, but they were very secure because you had to reach down and push in on a button on the side of the pedal to release, so there was no possibility of accidental unclipping.

I am not sure that would be a big problem with this design. I think a lot would depend on the shoe having tread to help guide you in. Also with having tread, it might be a little more walkable for when you are off the bike. It is an interesting concept, I would like to see them in action.

I can see it as a great mountain biking pedal (that's how he was talking about) if you can engage quick and easily, but I don't see it as an improvement for the road.

If you can't get in/out of SPD pedals, you probably shouldn't be riding clipless.
