I just want to echo the calls on here for Speedplay frogs. There is no spring in the system, you simply move your heel over a little bit to get out, and lift up your foot, and your'e out. I'm not sure how many degrees you have to move your heels, but I can tell you that they are the easiest pedal in the world to get out of. I dont' even think about getting out of them, I just put my foot down, they are that easy. Oh, and I should add that I worked at a bike shop for 5 years and recommended these to everyone who couldn't get used to spd's, and no one ever returned them. You can find them used on Ebay pretty regularly. Good luck!
