Pros: 4 sided very easy entry, simple to repair/rebuild (though I haven't had to), nothing sticks to/in them.
Cons: not an option to ride without clips, hitting anything on the trail will pop you out of the clips
Recommendation: the deal on these was too good to pass up, so despite my hesitation about these being my first clip-ins and not having any platform, I decided to go for it.
I couldn't be happier. entry is very easy. No platform hasn't really been an issue. there are times when I would like to get a crank going before i step in but it has just taken some getting used to. they don't feel any different from my friend's Candy pedals once you're clipped in, so you won't miss the platform unless you want to ride in regular shoes sometimes.
Pros: They shed mud, dirt, snow, and all kinds of muck you can throw at it easily. Mine have taken a good couple of hits and are still very solid. They release from your cleats pretty easily.
Cons: They can be a bit of a pain to get in sometimes.
Recommendation: The pedals are for the most part easy to use, easy to install, easy to come out of it when you want to, and are durable. They make riding my bike alot less of a chore when hitting the trails.
Pros: I have ridden many clipless pedals and these by far are the best. They never clog even in the mud. Easy entry by either pulling your foot back or pushing forward. Four sides make it easier to enter.
Cons: Not a large platform. If your out of the clips occationally then these aren't for you.
Recommendation: Get them if you want clog proof, bomb proof pedals. I have them two years and no problems.
