Initially, I was going to say, "That's bike racing!" But from what I see on that clip, it looks like you weren't taking the same line as everyone else. You said you were matching the line of the black and white guy (on your right). With the turn coming up, you should have shot past him so that you have a better line in the turn. Once your hips are past his handlebars, you can move over on him while still giving him enough room to get through the turn safely. I mean, don't chop him into the curb. (Though I know a lot of guys who would do that.)
I'm watching
#901 aim for the
apex. That's a predictable move on his part.
I'm also watching your line in relationship to the seam in the pavement. You can see that you're allowing too much room for the b&w guy.
It looks like you were too generous.
What am I not seeing on the video?
