I'm sorry but I just don't get it. The continuing mystery and angst that seems to surround clipless pedals is baffling to me.
I've been riding clipless on all my bikes for 10 years, Commuter/Road/MTB. I set the tension properly, I maintain them, and I've never had a fall due to not being able to unclip. They are far easier to get out of than toe clips or powergrips, and I just can't imagine my riding experience without the benefit of being clipped in.
Am I missing something?
