I was riding home tonight on my recently converted Raleigh. I took a fairly sharp left turn when my pedal got caught on the ground and sent me flying and tumbling. I normally ride a Langster with 170 cranks but clipless. Should I change out the cranks or pedals on my Grand Prix or just learn not to be an idiot? It all happened really fast. Before I even realized what happened, about five people were encircling me. I was waiting for one to poke me with a stick. Luckily my backpack took the brunt of the fall. So any advice?
