It's bad enough the nonsense (in my personal opinion) Speedplay puts out about weight, contact area, etc. Sure, most companies overhype/mislead/lie with their marketing, but I find this offensive:
"Is the weight of a pedal system important?"
"Yes. All pedal system weight, like wheel weight, is rotating weight. It is twice as important to reduce the weight of rotating parts on a bicycle than it is to reduce the weight of non-rotating parts. An old bicycle saying says it all: "A pound off the wheels is worth two off the frame." The same can be said about pedals."
I get really irritated when companies treat us like children (much the way the current Bush administration does, but that's a whole other thread). I'm done venting, now.
Caveat: I understand that some people have Speedplay's and love them. I used to have a pair, but have switched to Ultegra's. I really liked the feel of the Speedplay's and I wish I could ride them -- they just didn't work out for me.
