With this post I wasn't really trying to get anyone to try Speedplays and I certainly could care less about debating them. I just thought I’d put another review out there for people doing research and make a suggestion for people with knee pain. I know there’s other pedals that have lots of float but I don’t think anyone makes a pedal like Speedplay in terms of float adjustability. My wife uses Shimano R-540 SPD-SL pedals, the most inexpensive model there is ($34 on Nashbar) and she loves them. She clips in and out easily and doesn’t have any pain issues so I told her to keep using those even though I’m enamored with my Speedplays. If you’re not entirely happy with your pedals (or any bike part for that matter) experiment and try something new. If your experiment works then great, if not then keep trying other things. But we all know if it ain’t broke don’t fix it! I however, wasn’t pleased with the fluidity of the clipping out on my Shimanos and I was having knee pain so I thought I’d try something different. As it turned out the Speedplays were better for me in both those areas as well as many other areas. Also, I may have given people an overly strong impression of how hard they are to walk in. They aren’t THAT much harder to walk in than my Shimanos and like I said, I easily and quickly snap on the $15 Kool Kovers whenever I step off the bike and it’s all good. Easy walkin, clean cleats, and easy storage of the Kool Kovers in my jersey pocket or top bar bag. My buddy uses Speedplay light actions and he doesn't even own a pair of cleat covers. He could care less about them. I've never heard him complain about walking in them, he's never slipped, and he's never had any trouble with debris clogging them up. But I'm the cautious type.
