Ok, if you want something with a platform this is not it. However, if you can put your feet on the pedals properly they are the way to go. This is the flagship for Shimano's pedals. Check out the DX or M545 - they are running this same retention system. It's adjustable, zero maintenance, chromo axle, easy to clean if you have to and easy to install and remove with all the clearance. All these great things will come at a price, though! You have to get the proper cleatseparately. This pedal comes with a #51 single release cleat from Shimano and to really enjoy this pedal for what it is, you need to spend an additional $17-$23 for the multi-release Shimano cleat.
Now you have light, amazing retention and a release that can be tuned by the rider. I think the DX does come from Shimano with the #56 cleat and is why it gets the rave reviews. This is the DX naked of its resin cage. Don't be shy on these. For under $30 I have paid more and gotten less before. Get them now if you're in the market and don't forget to get the right cleat. #56 multi release. It is not included unfortunately.
Every review board on the web rates this pedal as the ONE. If you need the platform go DX - same pedal with resin cage. Don't go with alloy cage - they rattle!
