My bf put a pair of Speedplay Zero's on my bike and I have had the most difficult time clipping in. He thinks that I may not weigh enough to properly clip in to use them. I have the screws on the cleats as loose as they can be. I can cllp in if I push down, jump on the pedal, and shift all my weight onto one leg--and only if my bf holds my handlebars to steady me. I have been using SPD's and was hoping to switch to these rad new Speedplays

Has anyone else had problems with using Speedplay Zero's?
