We've been using it for about a week now. They seem to be quite profitable. All of these shows come with pre-drilled holes on the bottom for you to attach your custom spikes. I also bought a set of "Look Delta" cleats (that's what Peloton uses) with 9 floats (don't know what that means) but they cost under fifteen bucks and were on Amazon too. All that remains is to screw the mandrel with the tool provided.
