Some years ago, I bought an inexpensive pair of RITCHEY MTB pedals. I learned to ride clipless pedals with those, but I noticed that I was always fiddling with the adjustment. I found this quite annoying.

Next I bought a pair of Crank Bros. Quattro pedals. They billed these as their true road pedal with the EggBeater core, but a larger platform than the Candys. I REALLY liked those! No adjustment to mess with. Consistent clip in and out and little or no centering on the float. I probably would still be riding them, but I lost interest when Crank Bros. discontinued them.

That led me to what I've been using for the past several years: BeBop Pedals. They function as road and MTB pedals. I use them for my road bike with a pair of Pearl Izumi MTB shoes. They have no adjustments and a smooth, low force clip in. There is no centering on the float and like the Crank Bros. pedals, you can unclip in either direction. That's important to me as I can only unclip with an inward rotation. The pedals and cleats are very open, so any debris falls out or gets pushed out. They come in carbon steel, stainless steel and titanium varieties. I use the stainless ones and they are rebuildable.
