yea it happens to the best... and the worst of us. I was riding home from a party one night, really drunk, after mashing face with some girl I did not know. So I thought I was really cool. And I thought my converse all stars would stick to my spd's just fine. NOPE hit a pothole and put my foot through my front wheel. Rolf Vector Pros look cool but there is far too much space between the spokes. I fell straight on my head. No helmet of course and now I have a nice big scar on my temple.
