crank bros ftw, i had spds back in the day, could rip right out of em when i started hauling, especially up hills, even when i tightened them down, and then i couldn't get out of em, but that only happens when you really pull hard on the pedals... which is somthing you do on a fixie, can't pop out of egg beaters, and you have float so they are more comphy and better for ur knees, i kinda wanna put mallets on my ss so i can ride w/ reg shoes when i need to, but i already had the eggs lying around meh
