Well, I couldn't stay away from them yesterday. Went downtown, (well, a hooterville kind of downtown where I have to wave at every car or they get mad), so there are no intersection issues, and when I finally relaxed, I realized that my effort was going into making leg circles, not pushing down. A weird feeling at first, but it makes a difference. I'm thinking that these are a go... can't wait until my students see these little pedals on my bike. (I commute to school) I'm already the weird bike lady around here...
