Shimano PD-EH500 Single-Sided SPD Flat Pedals

What do you call this? A "double-sided" pedal? A "single-sided" pedal? It's both. It has an SPD cleat on one side, and a platform on the other. Don't want to be clipped-in the whole time? No problem. Flip it over and used it with regular shoes. Also comes with removable studs so it can be used casually, or use it as an aggressive trail pedal. Very versatile. Flats or clipped-in. It's your choice.
