I went clipless in January of this year, and most the time I thought I liked them. But I had a total of 4 falls. 2 the first day trying to stop (newbie falls), 1 on an 18% grade I could not sustain, and was going too slow to be able to get out of the pedals, and simply fell in slow motion trying to unclip. First 3 falls I had only bruising. Mother's Day, however, in a downpour, in a gentle turn my tires slipped abruptly, I heard a "pop, pop" before I even hit the ground, and I tore my ACL and MCL, entirely due to the clips not unclipping. I have switched out my shoes and pedals, had to wait 6 weeks to get back on my bike, tho I did use my trainer, and now, I even have a faster average than I did before my injury, which seems unreal. I thought I had read everything related to cycling, but I have since found out that women tear their ACL 10 x as often as men. I think they are dangerous. Everyone has their own comfort level, skills, etc, but no more clips for me ever!
