Yes, I've read those complaints, too, about the pedal 'flipping over' to the flat side when you're riding clipless & vice versa when you're riding in normal shoes & using the flat side. My experience is that no matter which side I want to be using, the pedal rotates naturally one way or the other when my foot is off/out of it. So, I guess the complaints are justified that others have posted...

Certainly with toeclips, the clipside rotates down due to weight. Some may find this too inconvenient, I suppose. My SPD/flat pedals don't do it quite as much. But even with the toeclips, it just takes a quick little nudge with my shoe(s) to get seated into them again. I guess I haven't used the clipless enough because getting clipped into them is a pain in b*tt. Once I'm in, it's dreamy but getting there is always a worry nudge. Never had that with toeclips...

Either way, the d*mn pedals rotate.

Perhaps the double-sided clipless pedals rotate just as much but since either side works with the shoes, folks don't have a complaint...?

Whatever, the pedal 'flip' doesn't really bother me since I'm not making many racing starts from stoplights...
