Crankwork ?Premium Clipless Pedal to Platform Adapters ?for Bike Bicyle

The idea of this item is very clever but in practice it isn't that simple. The curved nature of spd-sl cleats is incompatible with this flat pedal making the installation process painful also the weight of the clip on pedal makes the default position of the spd-sl upside down making these very hard to ride with in towns and cities where you stop often. I found myself pedaling on the underside of the Shimano pedal after a few miles because they are so hard to turn over on the move.Good idea, bad execution.
