Philip B.wrote a review of Shimano PD-A600 Premium SPD Pedal on September 7, 2012
If you're in and out of traffic, stopping at lights and numerous four way stops, these pedals are not for you. The spd clips gravitate toward the bottom, so first you have to turn the pedal over before you can clip in. Plus, it is very awkward riding them, lacking slip resistance, until you clip in. (Perhaps this is not such a problem for experienced cyclists.) Otherwise, these pedals work very well. They are great for touring outside of city streets.
