http://vimeo.com/24951572 Filmed a guy going down, trying to figure out what happened. I didn't see his brakes flash, or hear the bike rev up. His tires were fairly new (about 500 miles) and definitely warmed up. 20 mph corner, he was doing about 20-25. I had slowed to about 30 not to ass pack him and still was gaining on him. Besides the obvious that he was crossed-up and on the double, what does it look like happened?
