As a kid, you're bike seemed to be one way to measure how cool you were, and back then a set of plastic pedals screamed junk. If you didn't roll up with a big set of nasty beartraps covered in teeth you might as well not have anything at all, fast forward 15 years and all of a sudden plastic has been made a comeback! I was hesitant at first, mostly concerned with the obvious, are theses things really going to give me any grip? Are they going to hold up?  Well actually I have been more than happy with them so far. There are quite a few advantages really, they're light, they're cheap, and the provide plenty of grip without attacking my shins like a cheese grater, I can't count the number of times I've slipped a pedal and thanked myself for having these. There are a couple disadvantages, one, don't ride them with wet shoes because then they fell like someone covered you feet in grease, and two, the bearings aren't sealed so they don't last forever, but they do seem to hold up just as long as the unsealed aluminum versions. I picked up a pair from Eastern, but Odyssey has been making them for years, and Primo along with most other major parts manufacturers have all released a version, even some with removable teeth. These would also be great for non-BMX bikes as well, it would be a good addition to any commuter or cruiser where you just want to hop on and ride. While not for the ripper who wants his feet totally superglued to his bike and dosen't care what happens to his shins should they happen to come unstuck, I'm not that tough and dig my plastics.
