My first time on SPD pedals. Well, second if you count the day before where I practiced on this fancy clipless technology. Only fell one time. And it was this car for a girls that caused it. Not that they cut me off: I was approaching a stop light and they yelled "hey, biker guy!" It through me off my game, and I forgot I was locked into the pedals as I came to a complete stop...and fell sideways on my ass onto the curb. The girls were not impressed. I just lay there and pretended I was dead.
