Welcome to variety when it comes to this pedal. One side is a typical caged platform pedal, the terms so rarely used, most probably don't understand what it means. The other side is an SPD pedal while the flipped side looks like a pedal that wants to downhill. It allows the rider to be of two minds. One is the round the corner spin to run errands, the other is the ten mile ride to work. This way, you can ride in your sneakers for the short stuff and get out the MTB for the longer rides.
Single-entry SPD design with chromoly spindle provides plenty of strength and stiffness. The aluminum pedal body gives strength and sealed bearings that will roll smooth with low maintenance. The difference with these pedals and the A-520 is the single sided clip in. The advantage of having this is that you can run to the store, grab drinks with friends or stroll around the neighborhood with sandals! How awesome is that?
